First time here, 2nd week new to java, please help!

[tracydo]

Hi, I'm just 2 weeks into computer science 1. New to the world of java.
I'm working on the Monthly Mortgage Payment program and having some problems that I don't know how to fix. Any help greatly appreciated! I'm using JEdit & Terminal on imac. Thanx.

import java.text.*;   //for Decimal format class

public class Mortgage
{
	public static void main (String[] args);
	{
DecimalFormat num=new DecimalFormat (“$,###.00”);  //declaring variables

double P= 100000;  //mortgage Principal.
double I = 0.07;  //7% mortgage Interest.
double T= 12*30;  //30 years mortgage Term.

double MP = (((P*(I/12)) / (1-Math.pow((1/(1+I/12)),(T));  //Monthly Mortgage Payment
                                                                                                //Display variables

		System.out.println(num.format(MP));
		System.out.println(“The Monthly Mortgage Payment is: “+MP);

	}
}

1) You have some Unicode character or whatever in there. You have directional quotes. You want regular old quotes, so retype that "DecimalFormat" line and see if it gets rid of the coding error.
2) Delete the semicolon at the end of public static void main (String[] args); .
3) Please use code tags.
4) Look at any other quotes in your program and make sure they aren't slanted. See point 1.
5) Make sure you have an ending parentheses for every starting parentheses in your formula.

also tell us the exact question your teacher gave you so we have a better understanding of what you are trying to write.

more info you give us the better it will help us answer this for you.

here is the code fully fixed because your a newb p.s. im 12 lol

import java.text.*;

public class Mortgage{
	public static void main (String[] args){
		DecimalFormat num=new DecimalFormat ("$,###.00");
		double P= 100000;
		double I = 0.07;
		double T= 12*30; 
		double MP = (P*(I/12)) / 1-Math.pow((1/(1+I/12)),(T));

		System.out.println(num.format(MP));
		System.out.println("The Monthly Mortgage Payment is: " + MP);
	}
}

,Your Welcome

here is the code fully fixed because your a newb p.s. im 12 lol
,Your Welcome

>> p.s. im 12

This is a typo and you meant to type "13" right? Because you have to be 13 to join here, if you aren't I would have to ban you. :)

[Progr4mmer]

no i am not 12 as i said in a message to another mod

. I don't know what you are looking for but here is something. Read through your code again. You made a lot of small mistakes. Good luck!

/*
 * LET"S TRY THIS I HOPE IT HELPS
 */
import java.text.*; //for Decimal format class

public class Mortgage 
{
    static DecimalFormat DecF = new DecimalFormat("0.00");

    public static void main(String[] args)// ;
    {
        // DecimalFormat num=new DecimalFormat (“$,###.00”); //declaring
        // variables

        double P = 100000; // mortgage Principal.
        double I = 0.07; // 7% mortgage Interest.

        double T = 12 * 30; // 30 years mortgage Term.

        double MP = (((P * (I / 12)) / (1 - Math.pow((1 / (1 + I / 12)), (T))))); // Monthly
                                                                                    // Mortgage
                                                                                    // Payment
        // Display variables

        System.out.println(DecF.format(MP));
        System.out.println("The Monthly Mortgage Payment is: "
                + DecF.format(+MP));

    }
}

I did not delete anything. i only comment what I don't need ....Blahhhhhh!!! :p

[FireBlah]

Also, if you need the dollar sign there just add it as a string. "$" + DecF.... Just take your time, Okay?
