I'm making a loan calculator that uses compound interest... I need the program to return the monthly payment, how much of it is principal and how much of it is interest, which depends on how many months into your loan you are... So basically all I need is the algorithm to calculate how much of your monthly payment (depending on how many months in you are) is interest and how much of it is principal.

This is for college homework. Fictional bank. I would like the year to look like Year 1, Year 2, etc.
I am trying to change this code to use only integers to calculate the compound interest.
// Compound-interest calculations with for.
public class Interest {
public static void main( String args[] ) {
double amount; // amount on deposit at end of each year
double principal = 1000.0; // initial amount before interest
double rate = 0.05; // interest rate
[Code] .....
And here is the output I get :
Why do I get the output after year 2? I assume it has something to do with the remainder.
I also have to format this output with the decimal point, etc.. which I think I will be ok with after I get through this part.
I need getting started designing and creating a program that calculates simple and compound interest. Simple interest in this case means that interest is only applied to the original amount. For instance, if a person deposits $1000 at 10% annual interest, then after one year they would have $1100 (the original $1000 plus the $100 interest) and after two years they would have $1200 (the original $1000, plus the $100 earned the first year, plus the $100 earned the second year).
With compound interest, the interest is applied to all money earned. So, starting with $1000 at 10% annual interest, after one year the user would have $1100 (the original amount plus $100 interest) and after two years the user would have $1210 (the $1100 they started with at the beginning of the year plus the $110 interest).
The requirements of this program are:
-Create a class that will hold methods to calculate the interest. Do not include the main method in this class.
-In the class that is used to calculate the interest, include a method to print to the screen, by interest period, the starting amount for the period, the interest earned for the period, and the total amount at the end of the period. Note that each period represents the time frame for how often it is updated. If annual is selected the period is every year. If it is semi-annual it is every six months. If it is quarterly it is every three months.
-Create a demo class that will use your interest calculation class. Prompt the user for the original amount, the type of interest (simple or compound), the annual interest rate, and whether it is updated annually, semi-annually, or quarterly. Use method calls to your calculate interest class to do all calculations and display the result. Loop the program until the user chooses to quit.
Sample output ($10000 initial investment, 10% simple interest, annual, for 4 years):
Period Beginning Amount Interest Earned Ending Amount
1 10000.00 1000.00 11000.00
2 11000.00 1000.00 12000.00
3 12000.00 1000.00 13000.00
4 13000.00 1000.00 14000.00

I am creating an amortization schedule calculator and I'm having a bit of trouble with adding my table to the screen after I calculate everything.

I'm currently working on a loan calculator... The only problem I'm having is occasional values that have very long decimals... How do I round the decimals?
View Replies View RelatedIn the following piece of code Iam trying to display the the loan amounts of the various loan objects located in a binary file. Iam trying to do his using getLoanAmount() in the loan class. the program is compiling but nothing is showing up on he console.
Program
import java.io.*;
public class Exercise19_06 {
public static void main(String[] args) throws ClassNotFoundException, IOException {
ObjectOutputStream output = new ObjectOutputStream(
new FileOutputStream("loan.dat"));
[code]....
I am still having trouble with printing an amortization table for my program. This is the example the professor gave us and our program has to print exactly like this:
Please enter the amount of the loan (a number less than $1,000,000.00) 1000.00
Please enter the annual interest rate (between 2.0 and 15.0 inclusive) 10
Please enter the term of the loan (a number of years between 1 and 30 inclusive) 1
Your monthly payment is 87.92
| INTEREST | PRINCIPAL
MONTH 1 : 8.33 79.58
MONTH 2 : 7.67 80.25
[code]....
So far I have it so it works up to the table. How to get it to loop so it will print each month with the principal and interest. This is the part im having trouble with:
double principal = amount;
double principalPaid;
double interest;
double totalInterest;
double balance = amount;

I just cant seem to understand the order of precedence here.
class Test{
public static void main(String[] args){
int k = 1;
k += (k = 4) * (k + 2);
System.out.println( k );
}
}
From what I have read compound operators have the lowest order of precedence... But the above piece of code makes the assignment k = 1 + (k = 4) * (k + 2) before evaluating the rest of the statement first.
It then evaluates (k = 4) and proceeds with the remained of the statement 1 + 4 * (4 + 6)....
I dont understand why the first k is assigned 1 but the remaining ks 4. Should they not all be 1 or 4 (I would have thought 4, since += has the lost order of precedence so is evaluated last)??
I keep getting an error every time saying there is no main class ...

Is there some way to create compound shapes/paths in JavaFX?
For the record I'm not implying the use of the methods intersect, subtract, or union. These produce other shapes. A compound shape/path is one that has a knockout of some sort. For instance, a circle within a circle, such as in a 2d donut shape. Alternatives do not include a circle with a thick stroke nor an overlayed circle with the background color. Specifically, JavaFX supports the FillRule, in the case of the Path object. However, there doesn't appear to be an "add" method as there was in the Area shape in Swing.
calculate how long it would take to pay off a loan of 500 pounds if there was 10% interest monthly, and 100 pounds was paid each month. This code is in a pseudocode,
set months = 1
set balance = 500
set totalpaid = 0;
while balance > 100
balance = balance - 100;
set interest = balance * 0.1
balance = balance + interest
totalpaid = totalpaid + 100
months = months + 1
endwhile
totalpaid = totalpaid+balance
display "you paid "+totalpaid
display "It took you "+months+" months"
so I had to make a program that prompts the user to enter a loan amount and the years for the loan and I have the conversions and everything my only issue is that when the chart pops up it just looks like a bunch of numbers and its missing the column headers
for example
Interest Rate Monthly Payment Total Payment
import java.util.Scanner;
public class InterestRate {
public static void main(String[] args) {
double monthlypayment = 0;
double totalpayment = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter Loan Amount");

I am trying to make a program that compares the 3 different search algorithms(sequential/binary/hashing). I have already made the sequential search algorithm, binary and hashing part of the code.My program OPENS a data file, and then OPENS a key data file. and then searches through them using both. How to go about the binary and hashing search algorithm (in the driver program).

-base program
-driver program
-data file

I have been trying to create an algorithm for the computer in my Tic-Tac-Toe game? So I searched for some good ones, and found about this confusing but effective algorithm, at least if you get it working, called Minimax. I tried implementing it into my game. Let's say it was easier said than done. Sometimes I think it's working, but sometimes it doesn't work at all. How do I get my algorithm working? What the variables BEST_SCORE_COMPUTER and BEST_SCORE_PLAYER in my code should have as starting values.
Java Code:
import java.util.Scanner;
public class TicTacToe{
private static char BOARD[] = {' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '}; // This is the main board itself.
private static int ROWS[][] = {{0, 1, 2}, {3, 4, 5}, {6, 7, 8}, {0, 3, 6}, {1, 4, 7}, {2, 5, 8}, {0, 4, 8}, {2, 4, 6}}; // These are all the rows one can win by filling.
private static int SCORE, BEST_MOVE_COMPUTER, BEST_SCORE_COMPUTER = -1, BEST_SCORE_PLAYER = 1; // These variables speak for themselves.
private static byte TURN = 1; // 1 means player's turn, and 2 means computer's turn.

I have a set of numbers within a text file.
2 6
1 4 4 1
When the program reads these numbers it will start with the first line. It reads 2, this is the number of times the program should loop through the numbers of the second line. Next it reads 6, this is the number that the sum of numbers on line 2 cannot go beyond, it must equal 6 or be less than.
Next it goes to line 2 and processes the numbers, 2 is less than 6 so it gets processed, so is 4 and when added to 2 it equals 6. This passes the rules therefore gets processed and added together and put in a variable. Once 2 and 4 has been processed it gets put at the back of the number queue, so the numbers look like 1 1 2 4.
With one loop done there is only one left, so it processes the next sum of numbers 1 1 2 as these equal 4 and pass the rule. So these get added together and and put to the back of the queue, 4 1 1 2. But all the loops are finished and the sum of the last loop is added on to the sum of the previous loop. 6 + 4 = 10.
What I need the algorithm to do is print the sum of this whole process when it reads these numbers from a file. I am able to read the numbers from a text file but not sure where to proceed from there.
Also the set of numbers vary, for example the next 2 lines of numbers could be,
10 7
3 1 1 1 4 4
