Java While 循环

循环

循环可以在满足特定条件时重复执行代码块。

循环很方便，因为它们可以节省时间，减少错误，并使代码更具可读性。

Java While 循环

while 循环会不断循环执行代码块，直到满足特定条件为 true

语法

while (condition) {
  // code block to be executed
}

在下面的示例中，循环中的代码将一遍又一遍地运行，直到变量 (i) 小于 5

示例

int i = 0;
while (i < 5) {
  System.out.println(i);
  i++;
}

自己试试 »

注意： 不要忘记增加条件中使用的变量，否则循环将永远不会结束！
