Explanation
The provided Java program defines a base class Vehicle with a method called speedUp(). Two subclasses, Car and Bicycle, are created, each overriding the speedUp() method to increase the vehicle's speed by different amounts. The Car class increases the speed by 10, while the Bicycle class increases it by 3. The main class tests the functionality of the speedUp() method for both subclasses.
Step-by-step Instruction
Implement the Car subclass that extends Vehicle and overrides the speedUp() method to increase speed by 10
Implement the Bicycle subclass that extends Vehicle and overrides the speedUp() method to increase speed by 3
Define the main class with a main method to test the functionality of the Car and Bicycle classes
Time Complexity
The time complexity for the speedUp() method in both Car and Bicycle classes is O(1) because the operations inside the method execute in constant time.
Space Complexity
The space complexity for the program is O(1) as well, since the amount of memory used does not depend on the size of the input and only a fixed number of vehicle objects are created.
