Different ways to concatenate Strings in Java

You can concatenate two strings in Java either by using the concat() method or by using the ‘+’ , the “concatenation” operator.

Example

public class ConncatSample {
   public static void main(String []args) {
      String s1 = "Hello";
      String s2 = "world";
      String res1 = s1.concat(s2);
      String res2 = s1+s2;
      System.out.print("Concatenation using method:: ");
      System.out.println(res1);
      System.out.print("Concatenation using operator:: ");
      System.out.println(res2);
   }
}

Output

Concatenation using method:: Helloworld
Concatenation using operator:: Helloworld
