Problem statement

In this program, we will create a class with a method and constructor. Then we will create an anonymous object and call the constructor and its method.

An object which has no reference variable is called an anonymous object.

Java program to call a method using the anonymous object

The source code to call a method using an anonymous object is given below. The given program is compiled and executed successfully.

// Java program to call a method using

class Sample {
  void sayHello() {
    System.out.println("Hello World");
  }

  Sample() {
    System.out.println("Constructor called");
  }

}
public class Main {
  public static void main(String[] args) {
    new Sample().sayHello();
  }
}

Output

Constructor called
Hello World

In the above program, we created two classes Sample and Main. The Sample class contains a constructor and sayHello() method.

The Main class contains a method main(). The main() method is the entry point for the program, here we created an anonymous object of the Sample class and called constructor and sayHello() method and printed messages.
