Submitted by Nidhi, on April 29, 2022

Problem statement

In this program, we will check whether an object represents a primitive type or not using the isPrimitive() method.

Java program to check whether the specified Class object represents a primitive type or not

The source code to check whether the specified Class object represents a primitive type or not is given below. The given program is compiled and executed successfully.

// Java program to check the specified Class object 
// represents a primitive type

public class Main {
  public static void main(String[] args) throws ClassNotFoundException {
    Class cls1 = int.class;
    Class cls2 = Class.forName("Main");

    boolean res1 = cls1.isPrimitive();
    boolean res2 = cls2.isPrimitive();

    System.out.println("Is int a primitive type : " + res1);
    System.out.println("Is Main a primitive type : " + res2);
  }
}

Output

Is int a primitive type : true
Is Main a primitive type : false

Explanation

In the above program, we created a public class Main that contains a main() method. The main() method is the entry point for the program. Here, we checked whether an object represents a primitive type or not using the isPrimitive() method. The isPrimitive() method returns true if the specified object represents a primitive type otherwise it returns false.
