Java 实例 - List 元素替换

以下实例演示了如何使用 Collections 类的 replaceAll() 来替换List中所有的指定元素：

/*

 Main.java

import java.util.*;
 
public class Main {
   public static void main(String[] args) {
      List list = Arrays.asList("one Two three Four five six one three Four".split(" "));
      System.out.println("List :"+list);
      Collections.replaceAll(list, "one", "hundread");
      System.out.println("replaceAll: " + list);
   }
}

以上代码运行输出结果为：

List :[one, Two, three, Four, five, six, one, three, Four]
replaceAll: [hundread, Two, three, Four, five, six, hundread, three, Four]
