  • How should a trainer handle rude participants in a training workshop?
  • Do’s and Don’ts for Trainer

The ability to handle rude participants is critical to success as a trainer as each trainer has at one or the other time encountered rude participants. The participants who continue talking, who work on their laptops while you are training, who continuously attend calls on their mobiles, who flat out say you are wrong or you have no clue what it is to be in their shoes, participants who recline on their chairs as if they are in a lounge, who ask irrelevant questions…. the list is endless.

So, what can you do to prevent rude participants from derailing or hijacking a training workshop?

1. Do some pre-work to ensure a great learning environment: Many things impact a participant even before they meet you: how was the training need communicated to them? Do they think they NEED training? etc. Many times these are out of our control but I like to request clients to copy me on emails they send to the participants.

2. Invest some time in the beginning of the session establishing your credibility and getting them to articulate why they should invest their time learning what you are going to cover.

3. Set the training norms collaboratively upfront: your expectations from them, their expectations from you should be on the table and any misalignment needs to be handled. Here come issues like late to class, talking instead of doing assignments etc. Discuss course of action if someone oversteps the boundaries that you all have collaboratively set. Agree on how you will handle disagreements if any i.e. agree on how to disagree.

So, basically we attempt to pre-empt rudeness.

If after all of this, someone is rude, then we can take recourse to some of the following strategies:

1. Isolate what form the rudeness is taking: talking amongst themselves, asking irrelevant questions, negative body language, refusal to engage in any of the activities etc.

2. If the rude participants are in a group, split up the group by doing an activity in which you shift people around in the room. My favourite is to use numbers to divide people into groups as it ensures people who are sitting together are not in the same group.

3. Move the rude participants to the front of the room. Basically near you. Now shower them with your keen attention.

4. Redirect their attention by making them participate in the training activities. Use persuasion.

5. For one off comments, say “interesting point of view, lets discuss in the tea break”, and move on without getting affected.

6. If they are asking questions or expressing views, give the participant a patient hearing and try to see it from their perspective. Let them fully express themselves, then if the question is pertinent to the topic answer it. You can also ask for their permission to park the question and answer it later. If they feel heard they will allow that.

7. Be assertive. Tell them that while you appreciate their views, you have differing views. You could also say that since their concern is not the concern of the majority you will handle it post the session.

8. If time is not permitting then tell them you will discuss it with them in the break. Then do not forget to do so.

9. Do not let it get personal. It should not be your view vs. theirs. Ask other participants for their take on the issue / question. Then wrap up with summarizing the views.

10. Humour if used appropriately, can work wonders.

Starting a series of some Java programs as many students were asking to share the programs. Here is the first program of the series.

Objectives:

  • Write a Program that calculates and prints the simple interest using the formula : Simple Interest = PTR/100
  • How to calculate Simple Interest in Java?
  • Write a program to calculate Simple Interest in Java.
  • Write a Java program that calculates and prints the simple interest using the formula : “SimpleInterest = PTR/100” and input values P, T, R should be accepted as command line.
  • How to use Command Line Arguments in Java?
  • How to pass values from command line in Java?
  • How to take input in Java from console?

 

This particular program can be written in various ways, we will try to write the solution program in different ways here and one can try to understand the difference between them.

Method 1 :

import java.util.Scanner;

public class SimpleInterestExample {

    public static void main(String[] args) {

        int p,t,r, result;

        Scanner sc = new Scanner(System.in);

        System.out.println("Enter the Value of P : ");
        p = sc.nextInt();

        System.out.println("Enter the Value of T : ");
        t = sc.nextInt();

        System.out.println("Enter the Value of R : ");
        r = sc.nextInt();

        result = (p*t*r)/100;
        System.out.println("Interest is : " + result);
    }
}

This one is the simplest way to write the program to find simple interest in Java. Here we have simply created the object of Scanner class for taking input. Scanner class was introduced in Java 6. To use Scanner class we will have to import the class from java.util package.

Method 2:

Now we will write a Java program that calculates and prints the simple interest using the Scanner class again but with object oriented programming approach.

import java.util.Scanner;

public class SimpleInterestExample
{
		double principalAmount = 0;
        double interestRate = 0;
        double term = 0;
		double simpleInterest = 0; 

    public void calculateSimpleInterest()
	{
		Scanner input = new Scanner(System.in);

		System.out.print("Enter the Principal amount : ");
		principalAmount = input.nextDouble();

		System.out.print("Enter the Rate As a decimal : ");
		interestRate = input.nextDouble();

		System.out.print("Enter the amount of time in years : ");
		term = input.nextDouble();

		simpleInterest = (principalAmount * interestRate * term) / 100;
	}

    public void displaySimpleInterest()
	{
		System.out.println("The Simple Interest is : " + simpleInterest);
    }
}

Mock Test Program for above code so that we can test the code. keep both the classes in same package and run the Mock Test Program or MockTestProgram.java

public class MockTestProgram{

    public static void main(String[]args);
	{
		SimpleInterestExample simpleInt = new SimpleInterestExample();
		simpleInt.calculateSimpleInterest();
		simpleInt.displaySimpleInterest();
	}
}

Method 3:

Now we will write a Java program that calculates and prints the simple interest using the formula : “SimpleInterest = PTR/100” and input values P, T, R should be accepted as command line.

import java.util.Scanner;

public class SimpleInterestExample {

    public static void main(String[] args) {
		double p,t,r, result;

		p = Double.parseDouble(args[0]);
		t = Double.parseDouble(args[1]);
		r = Double.parseDouble(args[2]);

		Scanner sc = new Scanner(System.in);

		System.out.println("Enter the Value of P : ");
		p = sc.nextDouble();

		System.out.println("Enter the Value of T : ");
		t = sc.nextDouble();

		System.out.println("Enter the Value of R : ");
		r = sc.nextDouble();

		result = (p*t*r)/100;
		System.out.println("Interest is : " + result);
    }
}

 

I will be sharing more programs soon as many students were asking for programs which were carried out during Java training and were asked in assignments after Java training. By the time enjoy coding in Java and use NetBeans, it will ease your life.

Hello everyone,

Jiri Kovalsky, Manager, NetCAT has announced NetCAT 8.1 and I have already registered for the same. And looking forward to have more people from all over the world and specially India for NetCAT 8.1.

NetCAT

You just need to invest few hours per week from mid July 2015 through mid October 2015. And you have to play a little with upcoming version of NetBeans, hunt for bugs and help community to release new and stable version of NetBeans. Make many new friends here and learn a lot from them. Get a chance to work with people having extreme experience and with very high profile in IT. You will never get such a chance with any other company or technology. The main thing you can mention that you have worked with NetBeans for that particular period as a Community Contributor.

Show your love towards NetBeans and technologies that NetBeans supports and earn lots of goodies depending on points you have earned for your work after completion of the program. If you wish you can select specific tribe and you can work with tribe on specific technology.

So what are you waiting for?  Visit http://wiki.netbeans.org/NetCAT and fill registration form, and hit Subscribe button after registration or send a mail to sympa@netbeans.org with subject line as “subscribe netcat” without quotes.

Recently I had a chance to visit Hyderabad again for Java Blogger Meet organized by Oracle, India on the occasion of very auspicious as Java turns 20. First of all I would like to thanks Oracle for all expenses paid trip including flight tickets to meal and cab fare too.

There were many rumours when Oracle acquired Sun Microsystems like Oracle will not looks after Java and Java will lose its importance and all but Oracle has always tried to groom Java and Java Community. Oracle always trying and helping people to get acquainted with Java. Oracle has planned a major release for Java every 2 years that means if Java 8 was launched in the year 2014 then Java 9 will be there in market by the year 2016. Many features are added to Java till now and many will come up in future.

In the journey of 20 years Java has grown from Oak to Java 8 and still counting. Java is programming language of future but now we can say that it has grown like Oak tree and will last for minimum 200 years more. I am using Java from Java 1.4.2. As Java turns 20 we celebrated the auspicious occasion and cut the cake, which was very well designed.

Java Bloggers Meet (7)

It was a very nice event overall wherein we get a chance to meet and hear many high profile people and community members like Sanket Atal (Group Vice President, Research and Development, Oracle), Shreekanth Narayanan (Director, Development Java Platform Group, Oracle), Vandana Shenoy (Director, Corporate Communications, Oracle) and Harshad Oak is after a long time. Harshad Oak is only Java Champion in India and his last name is similar to first release of Java and the coincidence he is the first Java Champion from India. We also got a chance to meet Bot-so which is a small robot who interacts with user via social network like Twitter developed by Debraj Dutta and team from Edifixio.

Java Blogger Meet, Oracle IDC, Hyderabad

Java Blogger Meet, Oracle IDC, Hyderabad

The main thing I have understood after the meet that Oracle is committed to Java from depth of heart so as Java community and Oracle is ready to help Java community in various ways. Java will remain number 1 programming language for centuries and my great great grand children may also be working on Java 1000 for spaceships or something like that. I will be there with Java and Java Community and will help them in all possible ways specially students, freshers and professionals.

If one face any difficulty in Java from any part of the globe, please feel free to contact me and will love to help you out and if something is there which I may not be answer Java Community and Oracle is also with us to answer all your queries. So if you are looking for a secured career be a Java geek and have a great future.

Objectives:

  • What is HashMap?
  • What is HashMap in Java?
  • What is HashTable?
  • What is HashTable in Java?
  • What are the differences between HashMap and HashTable?
  • What are the differences between HashMap and HashTable in Java?

HashMap vs HashTable

1. HashMap is non-synchronized. HashTable is synchronized.

2. HashMap is not thread safe. HashTable is thread safe.

3. HashMap allows one null key and any number of null values while HashTable do not allow null keys and null values in HashTable Object.

4. HashMap object values are iterated using iterator. HashTable is only class other than Vector class which uses enumerator to iterate values of HashTable object.

5. The iterator in HashMap is fail-fast iterator while enumerator for HashTable is not.

6. HashMap is much faster and uses less memory than HashTable.

7. HashMap is subclass of AbstractMap class. HashTable is subclass of Dictionary class which is obsolete in 1.7 and not in use anymore.

 

Dear all,

I am very happy to inform you that I am selected as Member of NetBeans Dream Team. It is an honor to be a member of NetBeans Dream Team and I am thankful of NetBeans Dream Team and NetBeans Team for considering me and my efforts towards Java and NetBeans, feeling honored since there are around only 50 people selected till now from all over the world and I am the 3rd Indian to be a member of NetBeans Dream Team after Mr, Tushar Joshi (Nagpur, India) and Mr. Rajmahendra Hegde (Chennai and Hyderabad, India).

11th Feb. 2015 was a great day for me, we had festival (Birth Anniversary) of Saint Gajanan Maharaj (Shegaon, Maharashtra, India) and same day only I have received mail with subject as Invitation to join NetBeans Dream Team!. This means all my faith in our saint and dreams have come true.

I am feeling more responsible now and I understand my responsibilities and will work as per guidelines of veteran members of NetBeans Dream Team. I am already working with a new JUG near Pune (Maharashtra, India) that is JUG Nashik (Maharashtra, India)  and will be there for few days with them from 13th Feb 2015. I will be working with 3 JUGs for now that is JUG Nagpur, JUG Pune and JUG Nashik.

For this, I would love to give credit to my family and specially to my Guide cum Mentor, Mr. Tushar Joshi. They have always encouraged me a lot even when many times I could not give them enough time due to hectic schedule of training session all over India. Also I would love to say thanks to my little son for coming in our life as a good luck charm only few days back. My wife was in also worried whether I will be there or not at the time of labor but never complained and said you just do your job, I will take care of everything.
