private float c;
private void method2(double y) {
c = y;
}
in another class we created an object of the first class then within in it :
tester.method2 (10.0f);
are there any errors ? how many errors if there are any and with explanation please.

- What is the difference between a method, a function, and an object?arrow_forward(Java) Question 5 Explain the answer step-by-step and include verbal explanation. Thank you! Write an interface as follows: The interface is named ServiceReminder It has one method named timeForService that has no parameters and returns a boolean variable. Now, update the below class so that is inherits from ServiceReminder Note that the next service date should be 90 days from the last service public abstract class Car { private double gasGauge; private double currMileage; private String color; private String make; private String model; private int daysLastService; public Car(String color, String make, String model, int daysLastService) { this.color = color; this.make = make; this.model = model; gasGauge = 0.0; currMileage = 0.0; this.daysLastService = daysLastService; } @Override public String toString() { return "Make: " + make + "\nModel: " + model + "\nColor: " + color…arrow_forward1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…arrow_forward
- Can we call the constructor of a class more than once for an object?arrow_forwardWhen can methods access the private instance variables?arrow_forwardAg 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…arrow_forward
- Classes and Objects) Hand-write a complete Java class that can be used to create a Car object as described below. a. A Vehicle has-a: i. Registration number ii. Owner name iii. Price iv. Year manufactured b. Add all instance variables C. The class must have getters and setters for all instance variables d. The class must have two constructors, a no-args and a constructor that receives input parameters for each instance variable.arrow_forwardPython Code: Write a class called Person with a constructor that takes two arguments, name and age and the saves these as attributes Write a method in this called print_person that prints out this information the console Confirm that you did it properly by instantiating an object called p1 and calling the method on the object. Lastly, extend the constructor by adding functionality that checks the input name only contains letters (no numbers allowed).arrow_forwardJava programarrow_forward
