Question

I have most of the code for this assignment but need some help getting the rest. Go to bottom to see what I have. Please help me figure out the foreach loops and the put() statement.

In this assignment, you will be using a new data structure, HashMaps, to repeat Assignment 8.3.

Main Method

• (5 points) Declare and initialize an HashMap with values of type of type Employee, and keys of type integer. In a while loop, keep initializing objects of type Employee, storing them in the HashMap, and allow the user to enter ID, salary, and leaveDays of the each employee one by one and in one line. Once the user entered a -1, stop initializing new employees, and print "You entered [actual length of array] employees. Thank you!"
• (5 points) In a foreach loop, go through every Employee object in the HashMap, and calculate their monthly payments, using the calcMonthlyPayment() method.
• (10 points) In a second foreach loop, go through every Employee object in the HashMap, and call their makePayment method only if their leaveDays is NOT higher than 21.

For this question if you receive 20/30 points, you have received the full points!

Sample Run: For the below input:

1 120000 6
2 50000 25
3 140000 4
4 112000 22
5 130000 4
-1

The output will be:

You added 5 employees! Thank you!
Monthly payment for employee 1 is calculated.
Monthly payment for employee 2 is calculated.
Monthly payment for employee 3 is calculated.
Monthly payment for employee 4 is calculated.
Monthly payment for employee 5 is calculated.
A payment of 10000 was made to employee 1.
A payment of 11666 was made to employee 3.
A payment of 10833 was made to employee 5.
