'{' expected

[elliojonhy]

Hey i've been studying java but i am stumped on this one so please help. I keep getting the error '{' expected Location line 4 even thought a '{' is on that line.
Code below:

import javax.swing.JOptionPane;
import java.text.NumberFormat;
import javax.swing.JTextArea;
public class myinput3.java { <- this is ment to be the line giving me the error
public static void main (String[] args)
{
String sinput;
int no_of_bolts, no_of_nuts, no_of_washer;
double bolt_price, nuts_price, washer_price, bolt_cost, nut_cost, washer_cost, total_cost;
NumberFormat money=NumberFormat.getCurrencyInstance();
JTextArea display=new JTextArea();
sinput =JOptionPane.showInputDialog("Enter the number of Bolts");
no_of_bolts = Integer. parseInt(sinput);
sinput =JOptionPane.showInputDialog("Enter the number of Washers");
no_of_washers = Integer. parseInt(sinput);
sinput =JOptionPane.showInputDialog("Enter the number of Nuts");
no_of_nuts = Integer.parseInt(sinput);
bolt_cost = no_of_bolt * bolt_price;
washer_cost = no_of_washer * washer_price;
nuts_cost = no_of_nuts * nuts_price;
Total_cost = bolts_cost + washer_cost + nut_cost;
System.exit(0);
}
}

Thanks in advance

That .java bit shouldn't be there. Try:

public class MyInput3 {

(The convention in Java is to start classes with a capital letter and use CamelCase. This applies to the filename as well.)

You should leave out the ".java" in the class name. Btw, you have some spelling errors for your variables further down as well.
