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

Code for passing data between activities in Android :

ActivityOne.java


String value = "Hello!";
Intent in = new Intent(this,ActivityTwo.class);
in.putExtra("Key", value);
startActivity(in);

ActivityTwo.java


Bundle bundle = getIntent().getExtras();
String valueReceived = bundle .getString("Key");

 

Code for passing multiple data or values between activities in Android :

Method 1 : Using Intent to pass data and Bundle to extract data between activities in Android

ActivityOne.java


String value1 = "Hello!";
String value2 = "Hi!";
Intent in = new Intent(this,ActivityTwo.class); 
in.putExtra("Key1", value1); 
in.putExtra("Key2", value2); 
startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String valueReceived1 = bundle .getString("Key1");
String valueReceived2 = bundle .getString("Key2");

 

Method 2 : Using Bundle to pass and to extract data between activities in Android

ActivityOne.java


String value1 = "Hello!";
String value2 = "Hi!";
Intent in = new Intent(this,ActivityTwo.class); 
Bundle bundle = new Bundle();
bundle.putString("Key1", value1);
bundle.putString("Key2", value2);
in.putExtras(bundle); 
startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String valueReceived1 = bundle .getString("Key1");
String valueReceived2 = bundle .getString("Key2");

 

Code for passing array between activities in Android :

ActivityOne.java

String[] array = new String[]{"Item1", "Item2", "item3", "Item4", "item5"};
Intent in = new Intent(this,ActivityTwo.class); 
Bundle bundle = new Bundle();
bundle.putStringArray("MyArray", array);
in.putExtras(bundle); 
startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String arrayReceived[] = bundle.getStringArray("MyArray");

 

Code for passing ArrayList between activities in Android :

ActivityOne.java

ArrayList<String> array = new ArrayList<String>();
array.add("Hello");
array.add("Hi");
array.add("Bye");
Intent intent = new Intent(this, ActivityTwo.class);
intent.putExtra("array_list", array);
startActivity(intent);

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
ArrayList<String> array = (ArrayList<String>) bundle.getStringArrayList("array_list");

Have fun with Intent.

Objectives :

  • Write a Java program to find prime number upto N number
  • Write a Java program to print prime number upto N number
  • Write a Java program to find prime number upto N number using Command Line Arguments
  • Write a Java Program to find prime number upto N number via Command Line Arguments
  • Write a Java program to find prime number upto N number using Scanner class

 

Java Program / Code :

Method 1 : Java Program to find Prime Number upto N number using Scanner class


import java.util.Scanner;
class PrimeNumber
{
public static void main(String[] args)
{
int n,p;
Scanner s=new Scanner(System.in);
System.out.println(“Enter number : ”);
n=s.nextInt();
for(int i=2;i<n;i++)
{
p=0;
for(int j=2;j<i;j++)
{
if(i%j==0)
p=1;
}
if(p==0){
System.out.println(i);
}
}
}
}

Method 2 : Java Program to find Prime Number upto N number using Scanner class and writing function to find prime number

Method isPrime() for checking if a number is prime or not

public class PrimeNumber{
 public boolean isPrime(int num) {
 if ( num < 2 ){
 return false;
 }
 for (int i = 2; i <= Math.sqrt(num); i++) {
 if ( num % i == 0 ) {
 return false;
 }
 }
 return true;
 }
}


// Mock Test Class to test above code
import java.util.Scanner;

public class Demo
{
 public static void main(String[] args) 
 {
 Scanner scanner = new Scanner(System.in);

 System.out.println("Please enter a number: ");
 int num = scanner.nextInt();
 
 if ( num < 2 ) {
 System.out.println("\n There are no Prime Numbers available");
 System.exit(0);
 }
 System.out.println("\n Prime Numbers from 1 to "+ num);
 PrimeNumber primeNum = new PrimeNumber();

 for (int i = 3; i <= num; i++) {
 if ( primeNum.isPrime(i) ) {
 System.out.print(", " + i);
 }
 }
 } 
}

Method 3 : Java Program to find Prime Number upto N number using Command line input


class PrimeNumber
{
public static void main(String[] args)
{
int n,p;
n=Integer.parseint(args[0]);
for(int i=2;i&lt;n;i++)
{
p=0;
for(int j=2;j&lt;i;j++)
{
if(i%j==0)
p=1;
}
if(p==0){
System.out.println(i);
}
}
}
}

Steps to run above program via command line :

  1. Compilation : C:\JavaPrograms>javac PrimeNumber.java
  2. Interpretation : C:\JavaPrograms>java PrimeNumber 20

Output :
