Question

while(true) {
    a=0;
    b=0;

    if(condition){
       a++;
    }else{
       b++;
    }

}

我有这段代码而且我不知道如何完成它。我希望它在a和b达到一定数量后离开循环。请帮忙。

Answer 1

a和b的声明必须在while循环之外。否则，它们将始终为0.您可以将while循环的条件更改为a < amount || b < amount，这意味着a和b尚未达到该数量。

int a = 0;
int b = 0;

while (a < amount || b < amount) {
    if (condition) {
       a++;
    } else {
       b++;
    }
}

Answer 2

使用标志布尔值而不是while（true）：

boolean flag = true;

while (flag) {
    // your loop
    if (a == the amount you want && b == the amount you want)
        flag = false;
    condition ? a++ : b++;
}

Answer 3

Assert.assertNotEquals( "", string );

Answer 4

 while (a != some_value || b != some_value2){
    a++; b++;
 }

Answer 5

while(true) {
    a=0;
    b=0;

    if(a >= your condition && b >= your condition){
       break;
    }else{
       a++;
       b++;
    }

}

Answer 6

尝试

int a = 0;
int b = 0;

while (b < amount) {
    if (a < amount) { // increment a if it is less than amount
       a++;
    } else if(b < amount) { // Now increment b, increment b if it is less than amount
       b++;
    }
}
