Concatenate null to a string in Java

Java 8Object Oriented ProgrammingProgramming

To concatenate null to a string, use the + operator.

Let’s say the following is our string.

String str = "Demo Text";

We will now see how to effortlessly concatenate null to string.

String strNULL = str + "null";

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 strNULL = str + "null";
       System.out.println("String concatenated with NULL: "+strNULL);
    }
}

Output

String = Demo Text
String concatenated with NULL: Demo Textnull
