  The requested program is given below.

  
  

  // superclass
  class Parent {
  	public void parentMethod() {
  		System.out.println("This is method of Parent class");
  	}
  }
  
  // subclass
  class Child extends Parent {
  	public void childMethod() {
  		System.out.println("This is method of Child class");
  	}
  }
  // Transaction class
  class Transaction {
  	public static void main (String[] args) {
  		// creating object of Parent
  		Parent p = new Parent();
  		// creating object of Child
  		Child c = new Child();
  		
  		// object of Parent calling method of Parent
  		p.parentMethod();
  		// object of Child calling method of Child
  		c.childMethod();
  	}
  }
  

  Output

  This is method of Parent class

  This is method of Child class

  
  

  Here, we created a class named Parent having a method named parentMethod. We also created a class named Child having a method named childMethod, which extends the Parent class.

  
  

  Inside the Transaction class, we created an object p of Parent and c of Child. Finally, the object p called the parentMethod() method of Parent and c called the childMethod() method of Child.
