Java Switch

switch picks one of many branches by value. Modern Java has an arrow form that does not need break.

ExampleJava

public class Main {
  public static void main(String[] args) {
    int day = 3;
    String name = switch (day) {
      case 1 -> "Monday";
      case 2 -> "Tuesday";
      case 3 -> "Wednesday";
      default -> "Another day";
    };
    System.out.println(name);

    // Classic form needs break
    switch (day) {
      case 3:
        System.out.println("Midweek");
        break;
      default:
        System.out.println("Other");
    }
  }
}

Output

Wednesday
Midweek

Tip: use the left and right arrow keys to move between lessons.
