Can you help me with this java code

CS1180 Lab 10 Inheritance This lab will give you an opportunity to explore the use of inheritance. This lab involves two classes, a Vehicle class which will be the base class for a GasGuzzler class. There is no I/O in either of these classes. There will also be a test class. The Vehicle class contains properties and methods that are common to all vehicles. This class contains two specific properties-speed- the rate at which the vehicle is traveling in miles/hour, and- weight-the weight of the vehicle in pounds. The Vehicle class has the following public methods: . Vehicle objects can be constructed 2 different ways: by specifying the weight and the speed, or by specifying the weight only in which case the speed defaults to 0. 2. There are accessor (getter) methods for both weight and speed. There are no setter methods. 3. The speedup method takes 1 parameter, the amount to increase speed by, and returns the new speed of the vehicle. The increase must be positive to have any affect. 4. The slowdown method takes 1 parameter, the amount to decrease the speed by, and returns the new speed of the vehicle-which can NEVER be a negative number! The decrease must be positive to have any affect. s. The brake method sets the speed to 0, and returns nothing. 6. The mom entum method returns the calculated momentum of the vehicle. The formula for calculating momentum is: weight 0.4536 *speed 0.447 7. The toString method should return a string indicating the weight of the vehicle, the current speed of the vehicle, and the momentum of the vehicle. Each piece of information should appear on a line by itself. A GasGuzzler IS A Vehicle, so the GasGuzzler class inherits from the Vehicle class
