System.out.println("Done"); 以上示例 2 层循环,外层 label 用 outerLoop 标记,内层 label 用 innerLoop 标记,跳出时用 break 指定要跳出到的 label 层。 封装方法里 return 将部分循环代码从主业务逻辑中抽出一个方法,然后通过 return 跳出,但这个只限定于退出到最外层。 public static void loop(...) { ...
In this example, you know exactly how many times the loop body needs to be executed because the control variable count is used to count the number of iterations. 上面这个例子通过控制变量count计数来告诉我们这个循环体到底执行力多少次。 This type of loop is known as a counter-controlled loop. ...
break;// terminate loop if i is 10 System.out.println("i: "+ i); i++; } System.out.println("Loop complete."); } } 在一系列嵌套循环中使用break 语句时,它将仅仅终止最里面循环。 例如: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 // Using break with nested loops. classBreakLoop3 {...
The Java control flow constructs are identical to those in C and C++, with a few exceptions.There is nogoto, but there is a "labeled" version of break that you can use to break out of a nested loop(Java中没有goto语句,可以使用带标签的break语句来跳出嵌套的循环)(where, in C, you perh...
