Fixed two things but there are still more that you will have to fix.

I fixed: a misplaced brace, and imported java.awt.Graphics
Next up: create the variable click

Ok you have a few problems here. The first is that you don't have a closing curly brace before the line 172 which closes off the paint method. Instead you have an extra closing brace all the way at the end of the program that should not be there.

My guess is that you are trying to write in an inner class but it can't be defined inside another function. So make sure you close off the paint method and get rid of the extra one on the end.

Second problem is that in your paint() method you have the variables dblLoanDuration, dblLoanAmount, drawn, and paymentFormat variables which have not been defined. You didn't happen to copy this code from somewhere did you and forgot to carry along the variables definition?

Next you use the Graphics object in your paint. The graphics object is in the java.awt package, so import that at the top.

After that you declared your ClickListener as a variable click. Problem is, you defined this after you attempt to add it to your controls. So move it up before the section...

// Create Action Listeners
        calculate.addActionListener(click);

That way click will be defined before you put it in the control addActionListeners.

Once you fix all these errors, then you will get the program compiling and then you can continue with testing and tweaking.

Good luck to you.

Thank you for the help....as for the Create Action Listeners I did have it up but was moving it around trying to get things to work. I wont lie to you as for the Paint method this was what the teacher had put into the class forum and yes forgot to change the variables.

Paint is the way to go.

Here is some help from Sun:

And since I want to make sure that everyone gets the last part of this assignment, I am going to give you all a huge gift:

public void paint(Graphics g)
{
double width = 900.00;
int height= 400;
double x=1.0;
double y=0.0;
int counter = 0;
double xincrement = (width/(dblLoanDuration*12));
double yincrement = height/dblLoanAmount;

g.drawString("Payments", 65, 10);
while (counter <= 10) {
x = x + xincrement;
g.drawString(Integer.toString((int)((((dblLoanDuration*12)/10)*counter))), (int)((width/10)*counter)+55, 20);
counter++;
drawn = true;
}

double amount=dblLoanAmount;
double payment=amount/12;
g.drawString("Amount", 0, 20);
while (y < height) {
y = y + (height/12);
g.drawString(paymentFormat.format(amount), 0, (int)y);
amount = amount-payment;
}

This is an updated of my code and there are somethings I have not changed yet....as in some variables. But I changed where my ClickListener was and got rid of one of the curly braces at the very end of program, But now I have two errors that I had earlier and that was the reason I changed things around in first place.

The errors are as follows:

C:\MortgageCalculator5.java:176: illegal start of expression
private class ClickListener implements ActionListener {
^
C:\MortgageCalculator5.java:394: reached end of file while parsing
}
^
2 errors

Here is my changed code and I do know that I still have to define some variables left in my paint method.

Did you add the closing brace back in before the actual class on line 147? You add one to close off the paint and then you delete one at the end. You don't just delete the one on the end and that is it.

I did add one before line 147 and I took out the last one at the end. Unless I am missing one....But I dont see it. Also I have been reading over chapter in school book and I can not find what I am to set drawn variable too. He gave us the give me so to speak but all I see is where it is " drawn = true"! True to what? I am so frickin lost!

Hello guys,

I still have not been able to resolve this error in program.
C:\Assignment Programs Made Java 2\MortgageCalculator5.java:177: illegal start of expression
private class ClickListener implements ActionListener
^
1 error

Tool completed with exit code 1

Also I am trying to set my variables for the give me the teacher gave us on the paint method....but I do not understand drawn = true. If I am to set a variable to drawn....what would that be.....true to what? I am still lost!!
Update on code:

Can someone please help me....I can not see if there is anything else I need to fix if I can not get past this compile error! I know there is more things wrong with it!

[pbl]

I guess that

	// Create Action Listeners
	calculate.addActionListener(click);
	exit.addActionListener(click);
	calc.addActionListener(click);

	// Creating the event listener
	ClickListener click = new ClickListener();

should be replaced by

	// Creating the event listener
	ClickListener click = new ClickListener();

	// Create Action Listeners
	calculate.addActionListener(click);
	exit.addActionListener(click);
	calc.addActionListener(click);

but to see the ClickListener class you'll have to indent it to the left

from

	while (y < height) {
		y = y + (height/12);
		g.drawString(paymentFormat.format(amount), 0, (int)y);
		amount = amount-payment;
	}

	// begin the events
	private class ClickListener implements ActionListener

to

	while (y < height) {
		y = y + (height/12);
		g.drawString(paymentFormat.format(amount), 0, (int)y);
		amount = amount-payment;
	}
}
// begin the events
private class ClickListener implements ActionListener
{

Which means that you have to remove the last last last } in your file

Then you still have to define the undefined variables:
- dblLoanAmount
- drawn
- paymentFormat

Ok thanks pbl I will work on those and see what happens. But the question on my mind is "drawn = true;".....true to what I have been going over text book and googling it but I can not seem to see how or what I am to set it to. Like I told Martyr the paint method was a give me to all of the students in class by teacher. The paint method he wrote and he said we had to define the variables. OK that is fine with me but I do not understand drawn = true? I hope this makes sense to you.

Sorry didn't go that deep understanding your code...
just managed to find out the "class not found" error due to the fact that a } was missing and that you start a private class in the middle of a method

[cpeachy1223]

Sweet...pbl that did the trick on the compile error. Now I am only getting the compile errors because those variables are not defined!

Now if someone can just answer the post I added right before this one and explain to me about drawn = true I would be forever thankful! Be back in a few minutes working on other variables except the drawn one....because I do not understand that one yet.

[cpeachy1223]

Ok I added my variables and now I am getting a couple of different errors. I listed my variables but the errors say it may not have been initialized!

Java complains about the fact that db;:oanDuration might not have been initialized
And the Java compiler is right... you were abou to divide by 0
