class, interface, or enum expected, what does this mean?

[John Beese]

        processJButton = new JButton();
		processJButton.setBounds(20, 300, 100, 20);
		processJButton.setFont(new Font("Default", Font.PLAIN, 12));
		processJButton.setText("process");
		processJButton.setForeground(black);
		processJButton.setBackground(white);
		contentPane.add(processJButton);
		processJButton.addActionListener(

			new ActionListener()
			{
				public void actionPerformed(ActionEvent event)
				{
					processJButtonActionPerformed(event);
				}
			}
		);

 public void processJButtonActionPerformed(ActionEvent event)
	{
		getIntegerOne();
	}

These are my 2 sections of code that i think the problem is in. when i complie i get an error message on the public void processJButtonActionPerformed line saying. IncomeTax.java:180: class, interface, or enum expected. Ive googled it and the only thing i can find says i missed a semicolon or misspelled something, but it looks good to me. :/

It means that at that point in the code, it expects you will be starting another class (or interface or enum). If you aren't, then you have too many closing braces above there. Review your matching of braces and indentation of code.

Ah ok, this is my first multi class program, I'll finish writing and see what happens. Thanks

[fred rosenberger]

That is probably a mistake. if your current code is 200 lines, it is much easier to find the problem now than after writing an additional 200 lines.

right now, you're saying "I can't find the needle in this haystack, so I'm going to add MORE hay, and hope I find it".

Hey there,
It can be a mistake as simple as missing a semicolon in lines preceding Line Number 180 (the line where you said error is reported). So better fix this first before writing more code.

[Campbell Ritchie]

Missing a semicolon is very unlikely to produce that particular error.

well i wish i had read this before i went on writing all this other code, i wrote a bunch more stuff now im getting all sorts of errors from everywhere, and im really confused, Doesnt help Ive been getting pretty frustrated and changing stuff and re changing so now its just a big mess.

[John Beese]

So i rewrote the code and most of it works.

//class declarations
	TaxCalculator taxCalculator;
	NetCalculator netCalculator;

 public void getNet()
	{
		netCalculator = new NetCalculator(grossEarnings,uncleSamsCut);
		netEarnings = netCalculator.getResults();
		

		netIncomeJTextField.setText("" + currency.format (netEarnings));
		

    }

Im getting a cant find symbol error message on the NetCalculator netCalculator; line
and the same error on netCalculator = new NetCalculator(grossEarnings,uncleSamsCut);

I used the same code for a dfifferent part of the program and it worked just fine, what gives?

[Piyush Joshi]

This error means that It could not find NetCalculator.class file in classpath.

If NetCalculator is defined in a different package then you will have to import it. Check your import statements.

Im confused, I had 2 classes i needed to delcare a Tax Caculator class and a net Calculator, i did the same thing for both( I think) and i only get an error for the net calculator, Ive been doing this all day and im losing concentration. heres my entire import/ declare statement

/* import statement section */
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.*;


public class IncomeTax extends JFrame
{
	/* declaration section */
	//color objects
	Color black = new Color(0, 0, 0);
	Color white = new Color(255, 255, 255);
	
	// number formats
   DecimalFormat currency;
	
	//components
	JLabel grossWageJLabel;
	JTextField grossWageJTextField;
	
	JLabel incomeTaxJLabel;
	JTextField incomeTaxJTextField;
	
	JLabel netIncomeJLabel;
	JTextField netIncomeJTextField;
	
	JButton enterJButton;
	JButton clearJButton;
	JButton closeJButton;

   int grossEarnings;
	double uncleSamsCut;
	double netEarnings;
	
	//class declarations
	TaxCalculator taxCalculator;
	NetCalculator netCalculator;

this is almost my whole main method minus the clear and close commands

		/* main method */
   	public static void main(String[] args)
   	{
      		IncomeTax application = new IncomeTax();
      		application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   	}
		
		public void enterJButtonActionPerformed(ActionEvent event)
	{
		getGrossAmount();
	}
      
		public void getGrossAmount()
	{
		try
		{
			grossEarnings = Integer.parseInt(grossWageJTextField.getText());
			getTax();
			
		}
		catch(NumberFormatException exception)
		{
		      	JOptionPane.showMessageDialog(this,
		       	"Please enter Gross Amount!",
		        "Number Format Error", JOptionPane.ERROR_MESSAGE );
		        grossWageJTextField.setText("");
		        grossWageJTextField.requestFocusInWindow();
		}
	}

     public void getTax()
	{
		taxCalculator = new TaxCalculator(grossEarnings,uncleSamsCut);
		uncleSamsCut = taxCalculator.getResults();
		getNet();

		incomeTaxJTextField.setText("" + currency.format (uncleSamsCut));
		getNet();

    }
	  
	  public void getNet()
	{
		netCalculator = new NetCalculator(grossEarnings,uncleSamsCut);
		netEarnings = netCalculator.getResults();
		

		netIncomeJTextField.setText("" + currency.format (netEarnings));
		

    }

The 2 pieces of code for the CalculateTax and CalcNet have been written and are further down. Are you saying i need to declare it in the import statements section? Gonna rest on it and see if i cant figure it out tomorrow.

[Piyush Joshi]

Picture is pretty unclear till now.

Can you show what is your directory structure, how many classes have you written and especially where in the directory are the NetCalculator,IncomeTax,TaxCalculator classes defined.

[John Beese]

MIssed a bracket, works fine now!
