Need help with the code for it to work. This is the code I have and the prompt of the assignmentFor Checkpoint B you will extend Checkpoint A to do the following:Prompts the user for an additional parameter: the bound on the timescale n of the simulationIf a user inputs a negative timescale, the program should immediately print an error message and exit.The program will calculate ki,ui for every time i<n and output these populations at each stepIf the population grows negative, treat it as population that has become zero. 1. Prompts the user for an additional parameter: the bound on the timescale of the simulation• If a user inputs a negative timescale, the program should immediately print an error message and exit.2. The program will calculate ki, u for every time in and output these populations at each step• If the population grows negative, treat it as population that has become zero.Hint: your program will need a for-loop.

Computer Science Question
Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.
Differentiate parameters passing method i.e, by line, by reference, by parameter? with suitable examples.
Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.
