Program That Calculate Minimum Fixed Monthly Payment
Jun 11, 2014
I want to Write a program that calculates the minimum fixed monthly payment needed in order pay off a credit card balance.
the Amount is 3,500 the annual rate is 9.9%, the minimum payment is 2% a month. the fixed payment is 150.
By a fixed monthly payment, we mean a single number which does not change each month, but instead is a constant amount that will be paid each month.
The program should print out :
payment information:
new balance total .......
current payment due .......
if you make minimum payment (2%) you will pay of in .... months and you Will end up paying an estimated total of $........
if you make the fixed rate payment, you will pay of in .... months and you Will end up paying an estimated total of $........ and you will save $........

This is for a mortgage calculator and we have to use the math.pow method. I am getting results, but the results are wrong. The monthly payment is coming out to big.
Here is what it should be:
Enter loan amount: 10000
Enter rate: 4.5
Enter number years: 3
The monthly payment is: $297.47
Here is what I'm getting.
Enter loan amount: 10000
Enter rate: 4.5
Enter number years: 3
The monthly payment is: $566.06
Here is my code. I believe my issue is in the math.pow formula.
Scanner in = new Scanner(System.in); // input object
double loanAmount; //user input
double interestRate; // user input
double yearNumber; // user input
double monthlyPayment; // answer to math
double finalPayment; // output
double monthNumber; // year number converted of months
double monthlyRate; // converted intersted rate
[Code] ....
The monthly payment is: $%.2f", monthlyPayment); // Shows monthly payment

I am doing a program where i have to implement a payroll system into a company for hourly, fixed monthly and commission paid workers. I also have to put the method which i did. the problem is I cant tell if my calculation is wrong or if i am missing a codes some where. The output is not giving me the answer that I was at least expected,
Here is my method:
{
< double total_deduction;>
< total_deduction = gross_pay - deduction;>
< return total_deduction;>
}
< public static double calGrossH(double hours_worked, double pay_rate)>
[Code] .....
I have done a lot researching and have come up with some search with almost the same calculation and I have also asked employees of a company on how they calculated hourly rate, commissions rate and fixed rate for all workers and gotten the same response but for some reason the output is not what it is supposed to output. here is my output.
<
un:>
<please enter the number of employees to be processed 31>
<please enter employee id number 3669>
<please enter employee first name>
[Code] ....
I dont know if I am missing some calculation somewhere or codes been researching and bussing my brains to figure out where is the missing codes or calculation.

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"

What to do with this JAVA code?
This is the code that I need to do without using the Joptionpane:
An Internet service provider has three different subscription packages for its customers:
Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per month unlimited access is provided.
Write a program that calculates a customer's monthly bill. It should ask the user to enter the letter of the package the customer has purchased (A, B, or C) and the number of hours that were used. It should then display the total charges.
This is what I have so far : Cannot use Joptionpaneshowinputdialog
/* A demonstration of how to use Decision Structures
import java.util.Scanner;
/**
This program demonstrates a switch statement.
*/
public static void main(String[] args)
{
char packageLetter;
int hoursUsed;

I am doing a pretty basic program with a fixed origin city and five destination cities. I am having trouble with entering passenger details. This is what I tried, but then I cannot retain all passenger details to print later on in the final ticket.
System.out.println("Enter flight details of child passengers (below 12 years)");
System.out.println("Enter Name");
for(a = 1; a <= cp; ++a)
{
//cp is number of child passengers, a is loop variable
String name = br.readLine();
System.out.println("1. " + name);
}

I finished a game in Java and sent it to a friend. Launching the program in my computer worked just fine.
But he got this error : "Could not find the main classs: Main. program will exit"
My JRE version is the most updated one. His JRE was version 1.6. He updated his JRE, and the problem was solved.
This is a bit worrying for me, because as far as I know, 1.6 isn't a very old version of the JRE. It's not the most recent one, but not that old.
This is worrying because I'm planning on sending my game to a lot of friends, and trying to distribute it on the internet.
A lot of people don't have the most updated JRE. And they are mostly non-programmers, so I can't expect them to update to the newest version of Java upon downloading my game. They might not know what Java is, even though they got it on their computer, and upon receiving an error, they'll just give up on the game.
If my game wouldn't work with a significantly old JRE, that would be reasonable. It's part of the nature of working with Java. But the fact that a relatively updated JRE, 1.6, doesn't work with my game, is worrying.
*(Please note: My game isn't implementing anything "special". Swing and KeyBindings are the 'newest' additions to Java that I can think of inside my game)*.
In short, I'd like to know that my game works on most of the computers it tries to run on. Knowing that it doesn't work on a relatively new JRE, is worrying.
So I have two questions:
1. Is it normal, for a Java program, to have such "high" demands for the JRE version? Do a lot of Java games demand at least version 1.6 of the JRE? Is this common?
2. How can I find out the minimum JRE version requirement for my program? Is there a methodical way to do this, or do I just have to go through all the libraries I use in my game and figure out what's the JRE release version for each one?

I'm required to create a program that finds the minimum value in an Array of integers.
Here is my approach :
public class Person {
public static void main(String [ ] args){
int theArray[]=new int [10];
int result = 0;
for (int i:theArray){
if (i < Integer.MAX_VALUE)
[Code]...
I can't really progress from this position. I keep getting told to change the return type to int on main method, then when i do it says change it to void..

I am working on this rental program and got stuck in the last part. The program is about renting a car; after completing the rent process it displays the user who spent maximum and minimum rent. This is where I can't proceed. The program displays maximum values for both max and min. Here's the code I have written:
import java.util.Scanner; // program uses Scanner
public class CarRentalTest {
public static void main( String[] args )
{
System.out.println("Welcome to Rental Portal");
Scanner input = new Scanner( System.in ); // create Scanner to obtain input from command window
CarRental details=new CarRental();

double principal; // The value of the investment.
double rate; // The annual interest rate.
double interest; // The interest earned during the year.

My JTable has a row, row number 0, which I always want to be at the top.I tried the following two approaches, both without success:
1- Use a custom table cell renderer for the header, and create a header of two rows. the second row is my JTextField.
Problem: I cannot get the JTextField to function properly. (I've seen examples with a checkbox in the header, but that one just reacts to a click somewhere on the header, my textfield must be editable).
2- Use the first row of the table. This works quite nice. However, I must prevent row 0 to be re-ordered when sorting the table.
I was thinking to add a prefix (either something like "___" or "zzz" depending on current sorting mode), but I do not know which methods to adjust for this exaclty.
Another approach would be to have N textfields above the JTable in some layout (or two JTable's on top of each other).
However, Then I would need to react to the re-ordering and re-sizing of all columns as well, which does not seem easy to me.

I have spent the past 12 hours on it and have gotten no where. I need to create a program that will calculate different tax brackets. I have tried all combinations I can think of and can't get it to work!!! I am literally about to go insane! I need the program to calculate tax will be 1% for anything up to $50000. If the tax is over $50000, you keep that 1% of $50000 and then add the remaining. So for an income in the second range, it would be 1% of $50000, and then 2% of (income - $50000). This then continues for each range.
The problem I'm having is getting it to display the correct interest rates. I am not asking for you to write it for me. I want to learn. But at this point I have exhausted all resources available to me.
import java.util.Scanner;
public class Project3taxinfo {
public static void main(String[] args) {
final double RATE1 = 0.01; //1% tax on the first $50,000
final double RATE2 = 0.02; //2% tax on the amount over $50,000 up to $75,000
final double RATE3 = 0.03; //3% tax on the amount over $75,000 up to $100,000
final double RATE4 = 0.04; //4% tax on the amount over $100,000 up to $250,000
final double RATE5 = 0.05; //5% tax on the amount over $250,000 up to $500,000
final double RATE6 = 0.06; //6% tax on the amount over $500,000

Assume the tanker is a cylinder of length 19.35 feet and volume 1320 gallons. What is the diameter in feet of the tanker truck? To solve this problem, write a Java program to calculate the diameter. For full credit, your Java application must follow these specifications.
1. The program must interactively input the capacity of the tanker in gallons and its length in feet. This should be done in the main method of your Tester class.
2. The input data should then be used to construct a TankerTruck object. You will need to write the TankerTruck class.
3. A TankerTruck method should be used by main to calculate the resulting diameter of the truck in feet.
4. Your program should use the standard Java constant for the math constant PI.
5. The output should be displayed using fixed-point notation, rounding to one decimal place of precision

Write method distance, which calculates the distance between two points (x1, y1) and (x2, y2). All numbers and returned values should be of type double. Incorporate this method into an program that enable the user to enter the coordinates of the points, then calculate and display the distance by calling the method –distance.
I've tried numerous times to make it work and I'm on the right path, however I'm missing some things in the code to make my results look like this later on, which I've attached onto this post.

having some trouble doing this. Here are the requirements:
1)Write a program using loop and break to calculate the value of PI.
2)You can use the following equation to calculate PI. PI=4/1-4/3+4/5-4/7+4/9-4/11+4/13 etc.. The program shouldn't loop until the criteria is satisfied.
3)The criteria is the value of PI you get is very close to the “real” value (3.1415926), meaning that their difference
should be smaller than a very small numeric number, e.g., 0.0001).
4)The control structures you may need for this program are loop, if-else, and unlabeled break.
5)The output should have the format: for each iteration, it has iteration number and the corresponding value of PI until that
iteration. The last line would be the final value of PI.
Here is my code so far:
package ids;
public class IDS {
public static void main(String[] args) {
double pi = 0;
for(int i=1; i<=100000; i++){
if ((i%2)==0){
pi+=(4/(2*i-1));
