Java 实例 _ List 元素替换

Java 实例 Java 实例

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 文件

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", "hundrea");
 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: [hundrea, Two, three, Four, five, six, hundrea, three, Four]
