//test circle
		int j = 0;
		outer :
			for(int i = 0;i<10;i++){
				System.out.println("outer : i = " + i);
				inner :
					for(;j<10;j++){
						System.out.println("inner : j = " + j);
						if(j == 4){
							System.out.println("continue inner:");
							continue inner;
						}
						if(j == 5){
							System.out.println("break inner:");
							j ++;// have to increase
							break inner;
						}
						if(j == 6){
							System.out.println("continue outer:");
							j ++;// have to increase
							continue outer;
						}
						if(j == 7){
							System.out.println("break outer:");
							break outer;
						}
					}
			}

运行结果：

outer : i = 0
inner : j = 0
inner : j = 1
inner : j = 2
inner : j = 3
inner : j = 4
continue inner:
inner : j = 5
break inner:
outer : i = 1
inner : j = 6
continue outer:
outer : i = 2
inner : j = 7
break outer:
