Question

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 interest rate starting from 5% to 8%, with an increment of 1/8.

Answer 1

Answer:

Following are the code to this question:

import java.util.*;//import package

public class Main //defining a class

{

public static void main(String[] axc)//main method  

{

double Loan_Amount,years,Annual_Interest_Rate=5.0,Monthly_Interest_Rate,Total_Amount,Monthly_Payment;//defining variables

Scanner ax = new Scanner(System.in);//creating Scanner class object

System.out.print("Enter loan amount:");//print message

Loan_Amount = ax.nextDouble();//input Loan_Amount value

System.out.print("Enter number of years: ");//print message

years= ax.nextInt();//input number of years value

System.out.printf("   %-20s%-20s%-20s\n", "Interest Rate", "Monthly Payment","Total Payment");//print message

while (Annual_Interest_Rate <= 8.0) //use while loop to calculate Interest rate table

{

Monthly_Interest_Rate = Annual_Interest_Rate / 1200;//calculating the interest Rate

Monthly_Payment = Loan_Amount * Monthly_Interest_Rate/(1 - 1 / Math.pow(1 + Monthly_Interest_Rate,years * 12));//calculating monthly payment

Total_Amount = Monthly_Payment * years * 12;//calculating yearly Amount

System.out.printf("\t %-19.3f%-19.2f%-19.2f\n", Annual_Interest_Rate,Monthly_Payment,Total_Amount);//use print meethod to print table

Annual_Interest_Rate = Annual_Interest_Rate + 1.0 / 8;//use Annual_Interest_Rate to increating the yearly Rate

}

}

}

Output:

Please find the attached file.

Explanation:

In this code inside the class, several double variables are declared in which the "Loan_Amount and years" is used for input value from the user-end, and another variable is used for calculating the value.

In this code a while loop is declared that checks the "Annual_Interest_Rate" value and creates the interest rate table which is defined in the image file please find it.
