System.out.println(“This is a generic vehicle.”);

}

// Derived class (Subclass) extending Vehicle
class Car extends Vehicle {

// Override the displayInfo method from the Vehicle class
@Override
public void displayInfo() {
System.out.println(“This is a car.”);

}
// Additional method specific to Car
public void startEngine() {
System.out.println(“Car engine started.”);
}
}

// Main class to demonstrate method overriding
public class MethodOverrideBasicExample {
public static void main(String[] args) {

// Create an instance of the Car class
Car myCar = new Car();

// Call the overridden method
myCar.displayInfo(); // Outputs: This is a car.

// Call the additional method specific to Car
myCar.startEngine(); // Outputs: Car engine started.
}

}

Explanation:
1 Base Class (Vehicle):
• Contains a method named displayInfo to display generic information about the vehicle.
2 Derived Class (Car):

• Extends the Vehicle class.
• Overrides the displayInfo method to provide a specific implementation for a car.
• Adds an additional method startEngine specific to the Car class.
