What is default Keyword in Java

Last Updated: October 30, 2022 by Chaitanya Singh | Filed Under: java

The default keyword is used inside switch block to mark a default case.

Example of default keyword in switch block

  • Used to specify a default case, this runs when no matching case is being found.
  • It is placed in the end of the switch block and it doesn’t require break statement.
  • If there is matching case found then the default case doesn’t execute.

In the following example, we are demonstrating the use of default keyword in switch-case block.

public class JavaExample {
  public static void main(String[] args) {
    int num = 15;
    switch (num) {
      case 10:
        System.out.println("Execute this if num is 10");
        break;
      case 11:
        System.out.println("Execute this if num is 11");
        break;
      default:
        System.out.println("Execute this if num is neither 10 or 11");
    }
  }
}

Output:

Execute this if num is neither 10 or 11
