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 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]
