Java 范例 - List 元素替换
使用 Collections 类的 replaceAll() 来替换 List 中所有的指定元素
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); } }
编译运行以上 Java 代码，输出结果如下
List :[one, Two, three, Four, five, six, one, three, Four] replaceAll: [hundrea, Two, three, Four, five, six, hundrea, three, Four]
