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:
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] |
