Submitted by Nidhi, on April 29, 2022

Problem statement

In this program, we will use the newInstance() method, which is used to create a new instance of the class represented by this Class object.

Java program to demonstrate the newInstance() method

The source code to demonstrate the newInstance() method is given below. The given program is compiled and executed successfully.

// Java program to demonstrate the newInstance() method

public class Main {
  public static void main(String[] args) throws ClassNotFoundException, IllegalAccessException, InstantiationException {
    Class cls = Class.forName("Main");
    Object ob = cls.newInstance();

    System.out.println("Class is: " + ob.getClass());
  }
}

Output

Class is: class Main

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 represented class Main using Class.forName() method. Then we used the newInstance() method to create an instance of represented class. After that, we get the class name using the getClass() method and printed the result.
