SWITCH STATEMENT

When executing a switch statement, the program falls through to the next case. Therefore, if you want to exit in the middle of the switch statement code block, you must insert a break statement, which causes the program to continue executing after the current code block. 

SYNTAX 

switch(expression)

{

  case value-1:

              block-1

              break;

  case value-2:

              block-2

              break;

 

  default:

             default-block

             break;

}

                 

rest-of-code;

EXAMPLE PROGRAM:




public class SwitchCaseStatementDemo {

	public static void main(String[] args)

               {
		int a = 10, b = 20, c = 30;
		int status = -1;
		if (a > b && a > c) 

                {
			status = 1;
		} 

                else if (b > c) 

                {
			status = 2;
		} 

                else 

                {
			status = 3;
		}
		switch (status) {
		case 1:
			System.out.println("a is the greatest");
			break;
		case 2:
			System.out.println("b is the greatest");
			break;
		case 3:
			System.out.println("c is the greatest");
			break;
		default:
			System.out.println("Cannot be determined");
		}
	}
}

Output

c is the greatest
