Java 实例 - continue 关键字用法


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:

/*

 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.
