Question

JAVA*****************

In this assignment you will design a program that creates a class, then extends the class using Inheritance. You may pick any base class, such as car, or television. Then you must extend the class at least once.

import java.io.PrintStream;

public class Sub_class
extends Super_class
{
int num = 10;
  
public void display()
{
System.out.println("This is the display method of subclass");
}
  
public void my_method()
{
Sub_class sub = new Sub_class();
  
sub.display();
  
super.display();
  
System.out.println("value of the variable named num in sub class:" + sub.num);
  
System.out.println("value of the variable named num in super class:" + this.num);
}
  
public static void main(String[] args)
{
Sub_class obj = new Sub_class();
obj.my_method();
}
}

Explanation / Answer

Okay, so let';s start, we need to make a super class as well and add a display method to the parent class too.

Then we can call the display method of parent class and sub class both.

So the code after correction will be: -

import java.io.PrintStream;
class Cars
{
public void display()
{
System.out.println("This is the display method of Superclass");
}
}
public class Mercedes extends Cars
{
int num = 10;

public void display()

{
System.out.println("This is the display method of Subclass");
}

public void m1()
{
Mercedes sub = new Mercedes();
sub.display();
super.display();
System.out.println("value of the variable named num in sub class:" + sub.num);
System.out.println("value of the variable named num in super class:" + this.num);
}
public static void main(String[] args)
{
Mercedes obj = new Mercedes();
obj.m1();
}
}

Save the file as Mercedes.java, and then compile the file using the command javac Mercedes,java, to execute the file use the command java Mercedes.

This is all for the question.
