You found an exciting summer job for five weeks. It pays Php150.00 per hour. Suppose that the total tax you pay on your summer job income is 14%. After receiving your pay, you spend 10% of your net income to buy new clothes and other accessories for the next school year and 1% to buy school supplies. After buying clothes and school supplies, you use 25% of the remaining money to buy savings bonds. For each peso you spend to buy savings bonds, your parents spend Php 0.50 to buy additional savings bonds for you. Write a program that prompts the user to enter the number of hours you worked each week.

In this task, you are being asked to write a loop in Java.

Write a program that uses while loops to perform the following steps:

a) Prompt the user to input two integers: startingNum and endingNum (startingNum must be

less than endingNum).

b) Output all even numbers between startingNum and endingNum.

c) Output the sum of all even numbers between startingNum and endingNum.

d) Output the numbers and their squares between startingNum and endingNum.

e) Output the sum of the square of the odd numbers between startingNum and endingNum.

1. Create a program called WhileLoops.java. All loops will be written in this file.

2. Create appropriate variables and assign values using a Scanner object.

3. Correctly display appropriate messages.

Problem: Make a program that will accept 2 numbers and a choice of operation (1 = Display Sum, 2 = Display Difference, 3 = Display Product, 4 = Display Quotient, and 5 = Display All). if the choice input is not from 1 to 5, reaccept an input again. Display the selected option by the user.

Example input and output:

Enter number: 5

Enter number: 2

[1] Display Sum

[2] Display Difference

[3] Display Product

[4] Display Quotient

[5] Display All

Input choice: -1

[3] Display Product

[4] Display Quotient

[5] Display All

Input choice: 10

[1] Display Sum

[2] Display Difference

[3] Display Product

[4] Display Quotient

[5] Display All

Input choice: 5

Sum : 7

Difference: 3

Product: 10

Quotient: 2
