Concatenate String and Integers in Java

To concatenate a String and some integer values, you need to use the + operator.

Let's say the following is the string.

String str = "Demo Text";

Now, we will concatenate integer values.

String res = str + 1 + 2 + 3 + 4 + 5;

The following is the final example.

Example

Live Demo

public class Demo {
   public static void main(String[] args) {
      String str = "Demo Text";
      System.out.println("String = "+str);
      String res = str + 1 + 2 + 3 + 4 + 5;
      System.out.println(res);
   }
}

Output

String = Demo Text
