I see this board is very young. Well I'm a high school freshman in a java programming class and i have a little problem with my homework.

My source code is:

-----------------------------------------------------------------------------------------------

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.DecimalFormat;

public class DogsHumanAge extends JApplet
implements ActionListener


{
JTextField inputHumanyears, displayDogyears;

public void init()
{

JLabel labelHumanyears = new JLabel("Enter the dog's age in human years:",
SwingConstants.RIGHT);
inputHumanyears = new JTextField(5);

JLabel labelDogyears = new JLabel("Dogyears = ", SwingConstants.RIGHT);
displayDogyears = new JTextField(5);
displayDogyears.setEditable(false);
JButton go = new JButton("Compute age");
go.addActionListener(this);

Container c = getContentPane();
c.setBackground(Color.white);
JPanel p = new JPanel();
p.setLayout(new GridLayout(3, 2, 5, 5));
p.add(labelHumanyears);
p.add(inputHumanyears);

p.add(labelDogyears);
p.add(displayDogyears);
c.add(p, BorderLayout.CENTER);
c.add(go, BorderLayout.SOUTH);
}

public void actionPerformed(ActionEvent e)
{
int Humanyears = Integer.parseInt(inputHumanyears.getText());
double Dogyears = calculateDogyears(Humanyears);
DecimalFormat df = new DecimalFormat("00.0");
displayDogyears.setText(df.format(Dogyears));
}

private double calculateDogyears(int Humanyears, int Dogyears)
{
return 13 + (int)(16.0 / 3.0 * (Dogyears - 1));
}
}

-----------------------------------------------------------------------------------------------

The error message i get is:

DogsHumanAge.java:42: calculateDogyears(int, int) cannot be applied to (int)
double Dogyears = calulateDogyears(Humanyears);


The intent of this program is to calculate the number of dog years from the given human years that is inputted into the input box.

well im not 100% sure what the problem is but a buddy of mine was thinking it was the (int) in this line

try removing that and see what it does for you. i didnt try running your code, but when i get time i will try it out. hope this helps

Your problem is that you are not using the correct form of calculateDogYears(). You define the method as calculateDogYears(int,int) but only called it with one arg.

Error:

I would guess that you meant to do something like this:

//SIDEBAR: please use the CODE tags when posting code. It makes things so very much easier to read.
