sum in java

[Danny Gopie]

Hello

public class e29 {
public static void main(String[] args) {

String waarde = JOptionPane.showInputDialog(null,"Voer een getal
in","invoer getal",JOptionPane.QUESTION_MESSAGE);
int aantal = Integer.parseInt(waarde);

for ( int i = 0; i < 10; i++) {
int a = i * aantal;
System.out.println(a);

int b = Sum(a) / 9;
JOptionPane.showMessageDialog(null,b,"Gemiddelde",
JOptionPane.INFORMATION_MESSAGE);
}
}}

I can print the values of a correctly, but how do i sum all the values of a?
i tried Sum(a) but its not how it works in java i guess

Not sure, but isn't the following what you are looking for?

int sum = 0;

for ( int i = 0; i < 10; i++) {
int a = i * aantal;
sum += a;
}
