continue,break-优快云博客

本文通过两个示例展示了Java中break和continue关键字的用法。break用于立即退出整个循环，而continue则跳过当前迭代继续下一次循环。示例代码演示了当循环变量等于特定值时如何使用这些关键字。

The break and continue keywords are used to stop either the entire loop
(break) or just the current iteration (continue).


public class ForLoop {
	public static void main(String[] args) {
		for (int i = 0; i < 5; i++) {
			System.out.println("Inside loop, i = "+i);
			if (i == 3) {
				System.out.println("if is true: i == 3");
				continue;
				// compile error: says it's unreachable
//				System.out.println("after the continue statement");
			}
			// more loop code, that won't be reached when the above if test is true
			System.out.println("after the if statement, still inside loop");
		}
		System.out.println("out of loop");
	}
}

Output:

[b]Inside loop, i = 0
after the if statement, still inside loop
Inside loop, i = 1
after the if statement, still inside loop
Inside loop, i = 2
after the if statement, still inside loop
Inside loop, i = 3
if is true: i == 3
Inside loop, i = 4
after the if statement, still inside loop
out of loop[/b]
