please help!!!

[tootall2]

I am compiling a tax program and I have this compiler problem that I cant figure out . Can some one please help me. java:28: possible loss of precision
found : double
required: int
StateTaxDue = (0.03 * incomeValue - (600 * dependentsValue));

Heres my program:

import java.io.*;
import javax.swing.JOptionPane;
public class StateTax
{
public static void main(String[] args) throws IOException
{
BufferedReader inData;
inData = new BufferedReader(new InputStreamReader(System.in));

//declaring Variables
String income, dependents;
int StateTaxDue;
int incomeValue = Integer.parseInt(income);
int dependentsValue = Integer.parseInt(dependents);

//user input
System.out.println("State Tax Computation");
income = JOptionPane.showInputDialog(null, "Taxpayers Income:");
dependents = JOptionPane.showInputDialog(null, "Number Of Dependents:");

//Conversions
StateTaxDue = (0.03 * incomeValue - (600 * dependentsValue));

//output
JOptionPane.showMessageDialog(null, "State Tax Due:" + StateTaxDue);
System.exit(0);


}
}

this is because an int cannot handle decimal points, you need to use a double for the dependants and dependantsValue variable.
The compiler is telling you that you will loose the precision of your calculation if you use an int instead of double

When you cast a double to an int the JVM simply takes all the information held in the decimal points and gets rid of it. If you have the number 5.7 and you turn it into an int, you get 5. Any conversion that requires losing information like this need to be done explicitly (by casting). If you're going the other way, from an int to a double, then the JVM will do that automatically for you because no information has been lost.
