labeledwhile.java

几个简单的java学习代码

public class LabeledWhile {
  public static void main(String[] args) {
    int i = 0;
    outer:
    while(true) {
      System.out.println("Outer while loop");
      while(true) {
        i++;
        System.out.println("i = " + i);
        if(i == 1) {
          System.out.println("continue");
          continue;
        }
        if(i == 3) {
          System.out.println("continue outer");
          continue outer;
        }
        if(i == 5) {
          System.out.println("break");
          break;
        }
        if(i == 7) {
          System.out.println("break outer");
          break outer;
        }
      }
    }
  }
}
