boolean broken = false; // declared outside of the loop for efficiency
for (Type type : types) {
    for (Type t : types2) {
        if (some condition) {
            broken = true;
            break;
        }
    }

    if (broken) {
        break;
    }
}

您可以使用标签：

label1: 
for (int i = 0;;) {
    for (int g = 0;;) {
      break label1;
    }
}

如果是新的实现，可以尝试将逻辑重写为If-else_If-else语句。

while(keep_going) {

    if(keep_going && condition_one_holds) {
        // Code
    }
    if(keep_going && condition_two_holds) {
        // Code
    }
    if(keep_going && condition_three_holds) {
        // Code
    }
    if(keep_going && something_goes_really_bad) {
        keep_going=false;
    }
    if(keep_going && condition_four_holds) {
        // Code
    }
    if(keep_going && condition_five_holds) {
        // Code
    }
}

否则，当发生特殊情况时，您可以尝试设置一个标志，并在每个循环条件中检查该标志。

something_bad_has_happened = false;
while(something is true && !something_bad_has_happened){
    // Code, things happen
    while(something else && !something_bad_has_happened){
        // Lots of code, things happens
        if(something happened){
            -> Then control should be returned ->
            something_bad_has_happened=true;
            continue;
        }
    }
    if(something_bad_has_happened) { // The things below will not be executed
        continue;
    }

    // Other things may happen here as well, but they will not be executed
    //  once control is returned from the inner cycle.
}

在这里！因此，虽然简单的中断不起作用，但可以使用continue继续工作。

如果您只是简单地将逻辑从一种编程语言移植到Java，并且只想让它正常工作，那么可以尝试使用标签。

在某些情况下，我们可以在这里有效地使用while循环。

Random rand = new Random();
// Just an example
for (int k = 0; k < 10; ++k) {
    int count = 0;
    while (!(rand.nextInt(200) == 100)) {
       count++;
    }

    results[k] = count;
}

可以使用临时变量：

boolean outerBreak = false;
for (Type type : types) {
   if(outerBreak) break;
    for (Type t : types2) {
         if (some condition) {
             // Do something and break...
             outerBreak = true;
             break; // Breaks out of the inner loop
         }
    }
}

根据您的功能，您也可以从内部循环退出/返回：

for (Type type : types) {
    for (Type t : types2) {
         if (some condition) {
             // Do something and break...
             return;
         }
    }
}

如果有人在寻找添加标记循环的kotlin方法

loop@ for (i in 1..100) {
    for (j in 1..100) {
        if (...) break@loop
    }
}
