来自JOptionPane的总和输入

Question

The code I have is pretty clear, all it does so far is prompt the user for 10 inputs of integers, which I am trying to sum. I want to make it so that after each number is entered, it's added to the sum variable. How can i do this?
Here's the code.

int x = 10;
int i = 1;
int maxNumber = 100;
int sum = 0;

while (i <= 10) {
    x = Integer.parseInt(JOptionPane.showInputDialog("Enter one grade at a time."));
    i++;
}

Answer 1

You can do:

while (i <= 10) {
    x = Integer.parseInt(JOptionPane.showInputDialog("Enter one grade at a time."));
    i++;
    sum+=x; //This line will keep the total
}
