How to Replace an Element at Specified Index Vector in Java

In this example, we may see how to replace an element at specified index Vector object with set method.

Source Code

package com.beginner.examples;

import java.util.Vector;

public class ReplaceElementAtSpecifiedIndexVector {

	public static void main(String[] args) {
		
		//create Vector.
		Vector vector = new Vector();
	    
		vector.add("A");
		vector.add("B");
		vector.add("C");
		vector.add("D");
		
		System.out.println("Before element replacement ,Vector contains : ");
		for(int index=0; index < vector.size(); index++) {
			System.out.println(vector.get(index));
		}
		
		/*
		 * To replace an element at the specified index of Vector use set method.
		 */
		vector.set(2,"X");
		System.out.println("After element replacement ,Vector contains : ");
		for(int index=0; index < vector.size(); index++) {
			System.out.println(vector.get(index));
		}

	}

}

Output:

Before element replacement ,Vector contains : 
A
B
C
D
After element replacement ,Vector contains : 
A
B
X
D
