Java Examples - List Element Replacement

The following example demonstrates how to use the replaceAll() method of the Collections class to replace all specified elements in a List:

Main.java File

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);
    }
}

The output of the above code is:

List :[one, Two, three, Four, five, six, one, three, Four]
replaceAll: [hundrea, Two, three, Four, five, six, hundrea, three, Four]
