Test.java

public class Test {

  public static void main(String [] args) {
    Integer age = Integer.parseInt(args[0]);
    switch(age) {
      case Integer x && x < 0:
        System.out.println("Not born yet!");
        break;
      case Integer x && x < 18:
        System.out.println("Minor!");
        break;
      default:
        System.out.println("Let's have a drink!");
        break;
    }
  }
