Java标签用法

这是在Java中使用标签的好处之一：

block:{    // some pre    if(condition) break block;    // rest of pre that won't be executed if condition is true}

嵌套循环的另一种用法：

outterLoop: for(int i = 0; i < 10; i++){    while(condition)    {        // some pre        if(someConditon) break outterLoop; // break the for-loop        if(anotherConditon) break; // break the while-loop        // another pre    }    // more pre}

要么：

outterLoop: for(int i = 0; i < 10; i++){    while(condition)    {        // some pre        if(someConditon) continue outterLoop; // go to the next iteration of the for-loop        if(anotherConditon) continue; // go to the next iteration of the while-loop        // another pre    }    // more pre}
