Question

PLEASE DON'T USE COMPEX TOPICS ONLY, use scanners, peramathers, methods.....but nothing too complex..This is the 4th week of my CS 1 class anyway.

HERE is the Equation without the extra stuff, it's all I have to work from ===

// Compute result and report

months = MONTHS_IN_YEAR * years;

monthlyRate = (ratePercent / 100.0) / MONTHS_IN_YEAR ;

payment = loan * monthlyRate * Math.pow(1 + monthlyRate, months) /

(Math.pow(1 + monthlyRate, months) - 1);

Write a program that computes the monthly loan payment, given the loan amount (a

double value), the interest, as a percent % (a double value), and the number of years to

repay the loan (an int value). The calculation is to be performed in a method that is

called from main(). In main(), the calling method, you are to solicit the following values:

1. Loan amount, which is used for all calculations

2. The starting number of years to repay the loan, ending number of years to repay

the loan, and the incremental years.

3. The starting interest rate, as a %, the ending interest rate, as a %, and the

incremental interest rate, as a %.

You will the use for loops to create tables of monthly payments based on the number of

years to repay the loan, the table containing interest rate and the monthly loan payment.

The outer for loop will start with the starting number of years, continuing until the ending

year is reached or exceeded, incrementing then number of years each time through the

loop by the specified number of incremental year. For each year selected, display the

number of years, then follow with a table of monthly payments using interest rates

starting at the starting interest rate, continuing until the ending interest rate is met or

exceeded, incrementing the interest rate by the specified incremental interest. The table

will thus contain two labeled columns, interest rate and monthly payment. Refer to

Textbook Example Mortgage.java for soliciting User inputs and performing the monthly

payment calculation.

Sample Run for Problem 2

Enter the loan amount: 275000

Enter the starting number of years to repay the loan: 10

Enter the ending number of years to repay the loan: 20

Enter the years increment between tables: 5

Enter the starting loan yearly interest rate, %: 6.25

Enter the ending loan yearly interest rate, %: 7.25

Enter the increment interest rate, %: 0.5

Principle: $275000.0

Years to repay: 10

Explanation / Answer

import java.util.Scanner;

class chegg

{

public static void main(String args[])

{

double loanAmount,startInterestRate,endInterestRate,incrementInterestRate;

int startyearsToPayLoan,endyearsToPayLoan,yearsBetween;

Scanner input =new Scanner(System.in);

System.out.println("Enter the loan amount:");

loanAmount=input.nextDouble();

System.out.println("Enter the starting number of years to repay the loan:");

startyearsToPayLoan=input.nextInt();

System.out.println("Enter the ending number of years to repay the loan:");

endyearsToPayLoan=input.nextInt();

System.out.println("Enter the years increment between tables:");

yearsBetween=input.nextInt();

System.out.println("Enter the starting loan yearly interest rate, %:");

startInterestRate=input.nextDouble();

System.out.println("Enter the ending loan yearly interest rate, %:");

endInterestRate=input.nextDouble();

System.out.println("Enter the increment interest rate, %:");

incrementInterestRate=input.nextDouble();

double j,monthlyPayment,monthlyRate;

j=startInterestRate;

int monthsBetween;

for(int i=startyearsToPayLoan;i<=endyearsToPayLoan;i=i+yearsBetween)

{

System.out.println();

System.out.println("Principle Amount : "+loanAmount+" $");

System.out.println("years to repay :"+i);

System.out.println("Interest Rate Monthly Payment");

j=startInterestRate;

while(j<=endInterestRate){

monthsBetween=i*12;

monthlyRate=j/(12*100);

monthlyPayment=loanAmount *monthlyRate * Math.pow(1 +(monthlyRate),monthsBetween) /(Math.pow(1 + (monthlyRate), monthsBetween) - 1);

System.out.println(j+" "+(monthlyPayment));

j=j+incrementInterestRate;

}

}

}
