Java Practical Programs

 

1.     Write a program to check multiple conditions using if statement along with logical operators

 

2.     Write a program to check no is even or odd.

import java.util.Scanner; public class EvenOdd  {     public static void main(String[] args)      {         Scanner sc=new Scanner(System.in);         System.out.print("Enter a number = ");         int a = sc.nextInt();         if (a%2==0)          {             System.out.println("Number is Even");         }         else         {             System.out.println("Number is odd");         }     } }

3.     Write a program to check switch-case using character datatype.

import java.util.Scanner; public class SwitchCaseEx  {     public static void main(String[] args)      {         Scanner sc = new Scanner(System.in);         System.out.println("Enter one of these character (a,b,c,d) = ");         String a=sc.next();         char v= a.charAt(0);         switch (v)          {             case 'a':             System.out.println("Uppercase = A");             break;             case 'b':             System.out.println("Uppercase = B");             break;             case 'c':             System.out.println("Uppercase = C");             break;             case 'd':             System.out.println("Uppercase = D");             break;             default:             System.out.println("Invalid character");             break;         }     } }

 

4.     Write a program to display 1 to 20 numbers using for loop.

public class ForLoopEx  {     public static void main(String[] args)      {         for(int i=1;i<21;i++)         {             System.out.println(i);         }     } }

5.     Write a program to display 1 to 20 numbers using while loop

public class WhileLoopEx  {     public static void main(String[] args)      {         int i=1;         while (i<21)          {             System.out.println(i);             i++;         }     } }

 6.     Write a program to display 1 to 20 numbers using do while loop.

7. Develop a program to use logical operator in do while loop

8.     Write a program to display The Number on Button from 0 to 9.

9.     Write java program to demonstrate grid of 5*5 (Java AWT and Swing)

10.     Write a program to generate KeyEvent when a key is pressed and display “Key Pressed” message.

11. Write a Program to get Protocol , Path , Host , File , Port of the url using URL Class.
