labeledfor.java

几个简单的java学习代码

public class LabeledFor {
  public static void main(String[] args) {
    int i = 0;
    outer: 
    for(; true ;) { 
      inner: 
      for(; i < 10; i++) {
        System.out.println("i = " + i);
        if(i == 2) {
          System.out.println("continue");
          continue;
        }
        if(i == 3) {
          System.out.println("break");
          i++; 
          break;
        }
        if(i == 7) {
          System.out.println("continue outer");
          i++; 
          continue outer;
        }
        if(i == 8) {
          System.out.println("break outer");
          break outer;
        }
        for(int k = 0; k < 5; k++) {
          if(k == 3) {
            System.out.println("continue inner");
            continue inner;
          }
        }
      }
    }
  }
 
}

输出结果：

i = 1
continue inner
i = 2
continue
i = 3
break
i = 4
continue inner
i = 5
continue inner
i = 6
