Java Program to Concatenate Two Strings

This is a Java Program to Perform String Concatenation.

Enter any two strings as input. We have made a function into which we pass the two given strings and this function uses concatenation operator for string concatenation and hence return the desired string back to the main function.

Here is the source code of the Java Program to Perform String Concatenation. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  1. import java.util.Scanner;
  2. public class String_Concatenate
  3. {
  4.     public static void main(String[] args) 
  5.     {
  6.         String a, b, c;
  7.         Scanner s = new Scanner(;
  8.         System.out.print("Enter first string:");
  9.         a = s.nextLine();
  10.         System.out.print("Enter second string:");
  11.         b = s.nextLine();
  12.         String_Concatenate obj = new  String_Concatenate();
  13.         c = obj.concat(a, b);
  14.         System.out.println("New String:"+c);
  15.     }
  16.     String concat(String x, String y)
  17.     {
  18.         String z;
  19.         z = x + " " + y;
  20.         return z;
  21.     }
  22. }


$ javac
$ java String_Concatenate
Enter first string:hello
Enter second string:world
New String:hello world
