    Default Maximum Minimum Values

    I'm working on some code and the book I have is being of no real help as well as in the internet since most people use finding max/min in arrays but I need to use it from data entered by the user.
    PHP Code:
    import javax.swing.JOptionPane;
    public class exam
    	public static void main(String [] args)
    		String inputString;
    		int testnum=1;
    		int testScore;
    		double average;
    		int max;
    		int min;
    			inputString=JOptionPane.showInputDialog("Please enter your test score.");
    		JOptionPane.showMessageDialog(null,"The lowest score is " + min(testScore));
    		JOptionPane.showMessageDialog(null, "The highest score is " +max(testScore));
    		JOptionPane.showMessageDialog(null, "The average score is " + average);

    You'll find the min and max similar to how you'd manually do it with an array: have a min var that you'll compare the input to and if input is less, set = to input, and similarly for max (though you'll be checking if input value is greater than max of course). Also, you'll want a total value that you add as the values are input. Your testScore + testScore + .... will only add the last entered value ten times.

    Keep on working at it. Much luck!

    Crud, I didn't even see the error with finding the average. If I were to add another 9 lines and change testScore to testScore1 and so on. Would that work?
