This is my program so far. it is giving me one error in the second method for math with the max. and i do not know what to do. and also it gave me an error that it can't resolve the "." in JOptionPane.showMessageDialog after the math method. i just didn't put it in. I appreciate any help, cause i am clueless.

Code:

import javax.swing.JOptionPane;
public class program4
{
public static void main(String args[])
{
int x;
int y;
int z;
String one;
String two;
String three;
one=JOptionPane.showInputDialog("Enter First Number");
two=JOptionPane.showInputDialog("Enter Second Number");
three=JOptionPane.showInputDialog("Enter third Number");
x = Integer.parseInt(one);
y = Integer.parseInt(two);
z = Integer.parseInt(one);
}
public static int max(int x, int y, int z);
{
}
}

I am supposed to:

"Use a separate method for each of the following activities:

1) calculates the sum of four integers

2) select maximum number among four integers

You MUST use methods other than main( ) method."

and it is based off a program that asks you to input 4 integers, and it then calculates the sum of these 4 integers, and it selects the maximum among these four numbers. Finally, the program prints the results (the sum and the maximum) in a dialog box, each on a different line.

thanks again
