Write a Java program that would resemble a payroll system. An input window which will accept the employee number and the number of days of rendered work. A 2d-arraylist that contains the employee number and the rate per day is to be searched and used to compute for the gross salary. Gross salary is computed by multiplying the number of days of rendered work by rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and the net pay in an output window. Design your own input/output windows.
- Use c++ Q1. Create a library management system in which you have a pile of 4 books stacked over one another. Each book has a book number. Make a program in which a librarian stacks a pile of books over one another. A student wants to issue a book. The program first searches if the book is present in the stack or not. If the book hasn't been issued, the program finds out the index of the book. It also pops other books on the top of it to issue the book to the student. Display the books in the stack. (Hint: report the count of the books above the required book and use the pop() function "count" times.)You are required to implement a preprocessor in Java. Your preprocessor should be able to Identifying loops and methods on an input file, which will be a Java source file. ExampleA. Write a program that will input 10 numbers on the stack and will output how many numbers inside the stacks are positive even numbers and negative odd numbers. *Using Iostream*With Screenshot

You have a stack of "n" pancakes of varying sizes on a griddle. Your goal is to rearrange the stack in order so that the largest pancake is on the bottom and the smallest one is on top. You are only permitted to flip the top k pancakes, thereby reversing their order. Devise a recursive scheme to arrange the pancakes in the proper order that uses at most 2– 3 flips. Write a program to demonstrate how it works.
