0) Killing is not ideal. We use that only for VB programmers and/or puppy haters.
1) You cannot see running dll's in the task manager, they're libraries that are linked to dynamically by executables.
2) You're loading the froging thing from your main form! Keep hold of the reference then you can release it cleanly later.

This is the etiquette:
- Post question.
- Wait for answer.
Go off and do some work and maybe later:
- Post question.
- Wait for answer.

Do not flood the forum with one liners that don't actual contain anything that can be resolved.

We had made a JFrame in NetBeans with placing a JTabbedPane in it. There are six tabs with many swing components in it.
Net Beans generated the code automatically in "JFrameClass.java"
That made one class. We changed the components access specifier to public.
Now We made a new class "SetTabPane" extending "JFrameClass.java" using JTabbedPane of class JFrameClass. While running the program it gives an error "java.lang.NullPointerException" on the line accessing the object of JTabbedPane.

Can you help us ???
D'Oh! | :doh:

No code, no help.

Go help yourself. If you're using Netbeans you can run in debug and find the /bad/ code.

There have a method, this one is free. Any more you can either pay for on rentacoder like the rest of the dross, or have a go and then ask for help with code that you can't get to work. When there is not even a single snippet showing what you have tried, you deserve the pit of hell and not anything useful.

Hi am new to Java and programming in general. I have been trying to work on a project for school of which I have already posted ( a horrible version of the "program") though would just like to understand what I have done wrong. I don't like not knowing how to do stuff...

here is what I have posted :

/*
Write the program in Java (without a graphical user interface)
using a loan amount of $200,000 with an interest rate of 5.75% and
a 30 year term. Display the mortgage payment amount and then list the
loan balance and interest paid for each payment over the term of the loan.
If the list would scroll off the screen, use loops to display a partial list,
hesitate, and then display more of the list.
*/

package cr1;
import java.text.DecimalFormat;
/**
*
* @author
*/
public class CR1 {

/**
* @param args the command line arguments
*/

public static void main(String[] args) {
DecimalFormat dollarAmount = new DecimalFormat("0.00");

double loan_amount = 200000.00;
int years = 30;
// calculation number of payments
int number_of_payments = years*12;

double intrest_rate = 5.75;
double monthly_intrest_rate = intrest_rate/100/12; // calculates monthly inrest rate

// monthly payment

double monthly_payment = monthly_intrest_rate/(1 - Math.pow(1+monthly_intrest_rate,-number_of_payments)) * loan_amount;

double ipaid = monthly_payment * .0575;
int paymentnumber = 0;

int payCounter = 0;
int pCounter = 0;
double loanbalance = loan_amount - number_of_payments;

while (loanbalance > 0) //

if (payCounter == 0)

{
System.out.println("Starting loan balance: $" + dollarAmount.format(loan_amount));
System.out.println("");

payCounter += 1;
pCounter += 1;
}

else
{

System.out.println("Payment Number:" + payCounter);
System.out.println("Monthly Payment:$"+dollarAmount.format (monthly_payment));
System.out.println("Loan Balance: $" +dollarAmount.format (loanbalance));
System.out.println("Intrest Paid:$ " +dollarAmount.format (ipaid));

loanbalance = loanbalance - monthly_payment;
payCounter ++;
pCounter += 1;

}

if (pCounter ==9 )
{

try
{
Thread.sleep(200000);
pCounter = 0;
}
catch(InterruptedException CR1)
{

// message prints with Java-generated data
}
}

else
{
System.out.println("Than you for using Billy Bakers Program. Have a good DAY!!!");
System.exit(0);
}
}
}

Though I know it is not outputting the information the right way..it is supposed to have 360 payments and its not. I don't know if there is a problem with my math, loop or both. Could someone explain to me what mine eyes cant ?

Thank you very much,

Have you tried debugging it?

ps. Your not meant to put School Work on here as Chris Maunder Said at the top:
"9. If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums."

hmmm pie

That is not a big deal as I have said I have already posted and will receive a grade for the work above. I just want to understand what it is that I have done wrong. My teacher can read this forum and it will not be a bad thing. I am not asking for people to do my work, just help me understand what I am messing up on. I do not like not knowing or understanding something. I have looked in tutorials for Java, and found lots of information however, none that will help me explain my issues that I am having.

i.e. Am I using the wrong type of loop, not structuring it right or leaving something out.

However I completely understand if no one wants to look at it because its a school assignment.

Again, have you tried Debugging?

hmmm pie

Bactos9-Mar-09 11:19

9-Mar-09 11:19

Yes I have tried debugging it though at the moment it does not have any errors. The code works though I cannot produce the output that I would like.
It is producing the loan amount, the amount left on the loan and everything correct. It is having an issue with fulfilling the appropriate count for number of payments. It only goes to 172 payments instead of the 360 payments ( for the 30 year loan). I have tried using a "for" loop though all the examples I have looked at online seem straightforward however when I try it in (netbeans which is my compiler) it is giving me an error and will not let it compile.

I do :
for (int payCounter =0; payCounter => 359; payCounter++)
{
//code
}

It is telling me that a boolean is required and an int is not allowed, as well as an illegal start of expression.

As a side note I am not quite sure if it is my compiler or Java in general, can you not name a variable twice? I have tired to use say "payCounter" in the main code as well as in a statement though it will not let me compile saying it was already defined.

i.e.

main{
payCounter = 0;

//more variables

for (int payCounter =0; payCounter => 359; payCounter++)

{
//code
}

Though if I take out the veriable in the main when I use it agian in the "for" loop it says that it is undefined.

With debugging you go through the code line by line and have a look at what the variables values are.

Generally in a for loop when you declare the variable it shouldn't be used elsewhere.

The convention is normally to use "i" but it is not necesserily the case all the time.

Bactos wrote:
for (int payCounter =0; payCounter => 359; payCounter++)

Should be:

for (int i = 0; i < 360; i++)

As the loop will only run while i is less than 360 rather than payCounter having to be greater or equal to 359 which would never execute the loop as it starts as 0.
