Java 實(shí)例 - List 元素替換
以下實(shí)例演示了如何使用 Collections 類的 replaceAll() 來(lái)替換List中所有的指定元素:
/* author by w3cschool.cc 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); } }
以上代碼運(yùn)行輸出結(jié)果為:
List :[one, Two, three, Four, five, six, one, three, Four] replaceAll: [hundread, Two, three, Four, five, six, hundread, three, Four]
