I cant get this Message dialog to appear.

import javax.swing.JOptionPane;

public class calculateMeanAndSD {

static double marks;
static double mean;

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
for ( int counter = 0; counter < 10; counter++ ) {

marks = Double.parseDouble(JOptionPane.showInputDialog("En ter marks to compute Mean and Standard Deviation: "));
calculateMean();

}

}
public static void calculateMean() {
double sum = 0;
int j = 0;

sum += marks;
mean = sum / 10;
j++;

if (j == 10) {
JOptionPane.showMessageDialog(null, "The Mean of the marks entered is: "+mean);
} else {
System.out.print("");
}

}

}
=========================================
I cannot get this : " JOptionPane.showMessageDialog(null, "The Mean of the marks entered is: "+mean) " to appear.

much help would be appreciated. thanks

it will appear only if j's value is 10

I am very very new to java but I would try:

if(j.equals(10))

and printing j in the else clause to see what it's value is..

else {
System.out.print(j);
}

Other than that, I don't see how the value of j would ever be greater than 1 since every time you call calculateMean() you initiate it with 0 value... That being said, I would try passing "counter" as an argument to calculateMean()

PS: I am in the "Hello World" stage but I waned to see if I can make anything out of java code... I hope either that I helped you a bit or at least I didn't get on your nerves...

Cheers!
