Write the output of the following Java program and explain the results. public class Test {public static void main (String args[]} int index-3; switch(index} {case 1: System.out.println(\"equal to 1\"); break; case 2: System.out.println(\"equal to 2\"); break; case 3: System.out.println(\"equal to 3\"}; case 4: System.out.println(\"equal to 4\"); default: System.out.println(\"others\");}}}

Solution

Test.java

public class Test {
    public static void main(String args[])
    {
        int index =3;
        switch(index)
        {
            case 1:System.out.println(\"equal to 1\");break;
            case 2:System.out.println(\"equal to 2\");break;
            case 3:System.out.println(\"equal to 3\");
            case 4:System.out.println(\"equal to 4\");
            default:System.out.println(\"others\");
            }
            }
            }

Output :

Explanation :

The expression used in a switch statement is index whose value is 3.

So case 3 will execute.

If a break statement is reached, the switch terminates.

Here no break appears in case 3, so the flow of control will fall through to subsequent cases until a break is reached.

There is no break statement after case 3 so switch terminates after default case.
