In this chapter you will learn:

1. How to replace value in a list

Replace value in a list

static<T> boolean replaceAll(List<T> list, T oldVal, T newVal) Replaces all occurrences of one specified value in a list with another.

import java.util.Collections;
import java.util.Vector;
//j a  v  a  2 s .com
public class Main {
  public static void main(String[] args) {
    Vector<String> v = new Vector<String>();

    v.add("A");
    v.add("B");
    v.add("A");
    v.add("C");
    v.add("D");

    System.out.println(v);
    Collections.replaceAll(v, "A", "java2s.com");
    System.out.println(v);
  }
}
