Java continue 语句语句用来结束当前循环,并进入下一次循环,即仅仅这一次循环结束了,不是所有循环结束了,后边的循环依旧进行。
以下实例使用了 continue 关键字来跳过当前循环并开始下一次循环:
/* author by itshubao.com Main.java */ public class Main { public static void main(String[] args) { StringBuffer searchstr = new StringBuffer( "hello how are you. "); int length = searchstr.length(); int count = 0; for (int i = 0; i < length; i++) { if (searchstr.charAt(i) != 'h') continue; count++; searchstr.setCharAt(i, 'h'); } System.out.println("发现 " + count + " 个 h 字符"); System.out.println(searchstr); } }
以上代码运行输出结果为:
发现 2 个 h 字符 hello how are you.
