Concatenate Integers and a String in Java

To concatenate integers with a string value, you need to use the + operator.

Let’s say the following is the string.

String str = "Demo Text";

Now, we will concatenate integer values with the above string.

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

Example

 Live Demo

public class Demo {
    public static void main(String[] args) {
       String str = "Demo Text";
       System.out.println("String = "+str);
       String res = 99 + 199 + 299 + 399 + str;
       System.out.println(res);
    }
}

Output

String = Demo Text
996Demo Text
