一、一些常用的功能Java语句1.键盘录入Scanner sc = new Scanner(System.in); System.out.println("请输入数据:");//提示 int num = sc.nextInt();//一定要定义一个变量来接受录入数据注意: 提示必须在接收变量之前且紧接声明接收变量 2.数转百分数//第一种 double num = 0.16; //如果是整数类型 ...

在forEach中,不能使用 continue 和 break ,可以使用 return 或 return false 跳出循环,效果与 for 中 continue 一样,但是该方法无法一次结束所有循环...如果直接使用 continue 或者 break 还会报错,如下所示:[1,2,3].forEach(()=>{ break;})// SyntaxError: Illegal break statement...} finally { }/...
The Java break keyword terminates the for, while, or do-while loops. It may also be used to terminate a switch statement as well.

However, when i equals 5, the break statement is executed, terminating the loop early. Example 2: Using break in a while Loop public class BreakInWhileLoop { public static void main(String[] args) { int i = 0; while (i < 10) { if (i == 5) { break; // Terminate loop when i...
