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
importjava.util.*;
publicclassMain{publicstaticvoidmain(String[]args){Listlist = 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]
