Objectives:

  • How to use switch case in Java?
  • How to use switch case with string in Java?
  • How to pass string literals in switch case in Java?

 

Source Code:


public class SwitchWithStringExample

{
public static void main(String[] args)
{
String str = "two";
switch(str)
{
case "one":
System.out.println("one");
break;
case "two":
System.out.println("two");
break;
case "three":
System.out.println("three");
break;
default:
System.out.println("no match");
} // switch close
} // main close
} // class close

 

Steps to run above Java code:

Consider that we have saved code at C drive (c:\>) and the file is saved as SwitchWithStringExample.java

  1. Compilation : c:\> javac SwitchWithStringExample.java
  2. Interpretation : c:\> java SwitchWithStringExample

 

Output:

two

Objective:

  • How to use For Each in Java?
  • How to use advance for in Java?
  • How to use advance for loop in Java Programming Language?
  • Types of For loop in Java

 

Source Code:


class ForEachExample
{
public static void main(String args[])
{
//declaring an array
int a[]={1,2,3,4,5,6};

// Old way
System.out.println("Old way");
for(int i=0; i<a.length;i++)
{
System.out.println(a[i]);
}

//New way: for-each loop
System.out.println("For each");
for(int i:a)
{
System.out.println(i);
}
}
}

Objectives:

  • How to find the area of a circle in Python?
  • How to find the circumference of a circle in Python?
  • How to find the area and circumference of a circle in Python?

Python Code:


print("Enter radius of circle")
rad = input()
r=float(rad)
area = 3.14 * r * r
circumference = 2 * 3.14 * r
print(area)
print(round(circumference, 2))

Steps to Run the above code:

  • Navigate to the folder/directory where you have saved your python code or file.
  • Here I have considered that python file is saved on “c:\>” and the File name is “Circle.py
  • Just type the following command now to execute the Python program: c:\> python Circle.py

 

Download code:

  • Navigate to GitHub repository and download the code from here: Circle.py

Objective:

  • How to write Hello World in JavaScript?
  • How to write Hello World in JS?
  • How to print Hello World in JavaScript?
  • How to print Hello World in JS?

Source Code :

Here is the sample code for you:


<html>
<body>
<script language = "javascript" type = "text/javascript">

document.write("Hello World!")

</script>
</body>
</html>

Git Hub:

You can also download this code from link given here : Hello World in JS

Pattern 3 :

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1

 

Java Code for above pattern :


import java.util.Scanner;

&nbsp;

public class Pattern3

{

public static void main(String[] args)

{

Scanner sc = new Scanner(System.in);

//Taking rows value from the user

System.out.println("How many rows you want in this pattern?");

int rows = sc.nextInt();

System.out.println("Here is your pattern....!!!");

//Printing upper half of the pattern

for (int i = 1; i <= rows; i++)

{

for (int j = 1; j <= i; j++)

{

System.out.print(j+" ");

}

System.out.println();

}

//Printing lower half of the pattern

for (int i = rows-1; i >= 1; i--)

{

for (int j = 1; j <= i; j++)

{

System.out.print(j+" ");

}

System.out.println();

}

//Closing the resources

sc.close();

}

}

Output :

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2
