1.continue label

public void continueLabelTest(){
     outer:
      for(int i = 0; i < 5; i++){
          for(int j = 0; j < 6; j++){
              if(j == 4){
                  continue outer;
              }
              System.out.println(j);
          }
          System.out.println("test");
      }
      System.out.println("finish");
  }

2.break label

public void breakLabelTest() {
     outer:
     for (int i = 0; i < 5; i++) {
         for(int j = 0; j < 6; j++){
             if(j == 4){
                 break outer;
             }
             System.out.println(j);
         }
         System.out.println("test");
     }
     System.out.println("finish");
 }
