public class StringSwitchDemo { public static void main(String[] args) { StringSwitchDemo demo = new StringSwitchDemo(); String day = "Sunday"; switch (day) { case "Sunday": demo.doSomething(); break; case "Monday": demo.doSomethingElse(); break; case "Tuesday": case "Wednesday": demo.doSomeOtherThings(); break; default: demo.doDefault(); break; } } private void doSomething() { System.out.println("StringSwitchDemo.doSomething"); } private void doSomethingElse() { System.out.println("StringSwitchDemo.doSomethingElse"); } private void doSomeOtherThings() { System.out.println("StringSwitchDemo.doSomeOtherThings"); } private void doDefault() { System.out.println("StringSwitchDemo.doDefault"); } } |
