Q4: Define a class named Carthat has the following specifications: Two attributes: • plateNumber. to keep car's plate number as String value. • speed to keep car's current speed as integervalue. Seven methods: • Car( String pn, int s), a constructor method used to initialize the instantiated objects. • setPlateNumber( String pn), act as a set method for the attribute plateNumber. • setSpeed( int s), act as the set method for the attribute speed. • getPlateNumber(), act as the get method for the attribute plateNumber. • getSpeed(), act as the get method for the attribute speed. • fines (), returns the amount of traffic fine (500 SR) if car's speed exceeds 120 k/h, otherwise 0. • main(.), act as the main method for the program, and it should do the following: 1. Instantiate three objects, namely car1, car2, and car3, using the populated constructor. 2. Change the speed value of the first car (car7) to 130. 3. Change the plate number of the second car (car2) to "Java123". Homework3 CS2301 - 2/I| d 4. Print the following statement, The second car has the following plate number (plate number) and its current speed is (speed) 5. Using the fines()method, print the plate number and the current speed of the cars that have a current speed >= 120.
