#1804 — '{' expected

  To: comp.lang.java.gui
hi everyone, I'm new to the java world and I'm need of dire help, I
have been given an assignment and for some reason I cannot compile, I
keep getting the same error and even when I add an extra bracket the
error gets greater, here is the program and hopefully someone can help
me out.

import java.text.DecimalFormat;

public class Mortgage Payment Calculator {



//initialize numerical values
	public static void main(String[] args)

{

		//declared variables

	    int loanamount = 200000;
		double MP;
		double Principal=200000;



    	int[] months= new int[3];
		months[0] = 84;
		months[1] = 180;
		months[2] = 360;

		//calculate

		double[] interestrate= new double[3];
		interestrate[0] =  .0535;
		interestrate[1] =  .0550;
		interestrate[2] =  .0575;
		DecimalFormat twoplaces = new DecimalFormat("0,000.00");

		//calculate
		System.out.println("\tMortgage Payment Calculator\n");

		//looping in progress
                for(int counter = 1; counter <=12; counter++);
{
		//calculate


		PayMonthly = (loantotal * interestRate[i] / (1 - Math.pow(1/(1 +
interestRate[i]),loanlength[i]*12)));
{
		//calculate

		System.out.println("\tLoan Amount 1 = " + loanamount);
		System.out.println("\tYear Term is = " + yearterm[counter]);
		System.out.println("\tInterest Rate = " +
interestrate[counter]*100);
		System.out.println("\tMonthly Payment is " + twoplaces.format(MP));
}


}

}
}
}

Thanks Andrew, I closed the gaps and still this thing is making fun of
me, still getting the same error

You should really cite all the information, including the full, *copied* and 
pasted error message, within the body of the message, rather than merely 
hinting at it in the subject.  Nonetheless, it is clear what your difficulty is.

The error said '{' (left brace) expected, not right brace ('}'), so clearly 
adding right braces will not help.  Adding more right braces would help even 
less.  Why did you think right braces would help an error that refers to left 
braces?

Where would the compiler expect a left brace?  The first place is just after 
the class name in the class declaration:

>  public class Mortgage Payment Calculator {

but instead of a left brace, the compiler finds a token 'Payment' - whoops, a 
left brace '{' expected, but not found!

You have three class names in the declaration instead of only one.  Just use one.

this is what I have done so far and the following errors are

This is just plain wrong.  You don't put colons or periods in class names.

What are you using to teach you the language?  Doesn't it explain what the 
valid characters are for Java identifiers?

I think I missed that one, I'm really not very good at this, I got rid
of the colons and periods and now I'm getting

Once again, *copy* and paste the *entire* error message, along with the SSCCE 
(simple, self-contained correct (compilable) example) that causes it.  We 
can't keep guessing at what the trouble is with incomplete information.

You've allowed yourself to be driven by the error messages without 
really understanding them. I found it a bad idea, as a beginner, to 
write 100 lines of java and then try compiling it.

Start with this - does it compile?

   /*
    * MortgagePaymentCalculator.java
    */
   public class MortgagePaymentCalculator {
       public static void main (String[] args) {
           System.out.println("Mortgage Payment Calculator");
       }
   }

A good way for a beginner to work is to not add any extra code to the 
above until it compiles. Then add no more than two or three lines. Get 
that to compile before proceeding. Proceed in tiny steps.

If it compiles, what do you expect as output? Try running it and see if 
the actual output is as you expect. Don't add new functionality until 
the existing prototype behaves exactly how you expect.

Use indentation to help you see the structure of the program.

What RedGrittyBrick is teaching you is also the way to put together an SSCCE.

here is some generic advice:

1. use an IDE that formats your code. It makes bracketing errors much
easier to see.  See http://mindprod.com/jgloss/ide.html

2. look up error messages at

MP is declared here, but it never gets initialized. So when you use
it, your program will explode (not literally)

Just a small readability comment, you can have capitals in variable
names. interestRate is easier to read, no?

Uh oh. See that semicolon? That's breaking your code. When you do a
for loop in Java, there are two options for what follows: either a
block noted by {}, or a single line that ends with ;. What you're
doing here is telling Java "Do everything after for() but before ; 12
times," or, in your case, "Do nothing 12 times". As a result, in all
of the code you have in the {} block below, i isn't initialized, and
this code will only run once instead of 12 times, like you want.

>

> interestRate[i]),loanlength[i]*12)));

PayMonthly needs to be given a type the first time it's referenced. It
looks like you've got two variables to do the same job (MP and
PayMonthly) but if you only use each half of the time, neither gets
the job done.

Side note: general coding practice (at least in Java) is to name
variables and methods with lowercase first, classes with proper case,
and constants with all upper case.


Hope that helps some. And people are right - it helps others help you
if you're clear and specific about the problem you're having. Too
little and people can't help, too much and there's garbage to sort
through to find the problem.

Good luck,
Andrew

I would recommend going to your local library or book store and
getting a book on Java. Either that, or read the Java Tutorials:

Like what I'm doing right now is alternating between "The Java 
Programming Language Fourth Edition" for basic stuff, and "Effective 
Java" for more advanced stuff.  Both good books and both "From the Source"

Another excellent book is Head First Java, part of the Head First Series 
published by O'Reilly.

Thank you everyone, I really appreciate all of your help, I may not
know how to ask the right question since I'm merely a begginer.
