Homework 2 (Loops)

1. Interests.java: Write a program that lets the user enter the loan amount and loan period in number of years and displays the monthly and total payments for each annual interest rate     starting from 5% to 8%, with an increment of 1/8. Use double values for all the amounts and percentages. Hint:

monthlyInterestRate = annualInterestRate / 1200;

monthlyPayment = loanAmount * monthlyInterestRate / (1 - (Math.pow(1 / (1 + monthlyInterestRate), numberOfYears * 12)));

totalPayment = monthlyPayment * numberOfYears * 12;

For example:

Loan amount: 10000

Number of years: 5

Interest Rate

2. Pyramid.java:  Write a nested for loop that inputs the number of lines and prints powers of 2 as a pyramid pattern shown in the following example. You may assume that the user enters any number of lines up to 13.

Enter the number of lines: 8

Output:
