String Concatenation in Java

String Concatenation in Java

Concatenation is joining or combining two or more strings. In this java program, we are going to combine two strings to form a single one. This program will accept inputs from the user using the scanner class. It’s available in console and gui version.

Source code:

import javax.swing.*;
class ConcatStringGUI
{ 
public static void main(String[] args) {
	 
String firstname ; 
String lastname ;

firstname = JOptionPane.showInputDialog(null,"Enter your firstname:");
lastname = JOptionPane.showInputDialog(null,"Enter your lastname:");

JOptionPane.showMessageDialog(null,"Your fullname:" + firstname + lastname);

	}
}
