Java 實例 - List 元素替換
Java 實例以下實例演示了如何使用 Collections 類的 replaceAll() 來替換List中所有的指定元素：
Main.java 檔
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);
}
}
以上代碼運行輸出結果為：
List :[one, Two, three, Four, five, six, one, three, Four] replaceAll: [hundrea, Two, three, Four, five, six, hundrea, three, Four]
