Thread: How to "drop" scores?

Hello everyone, I was trying to create a program that allows the user to input 4-30 assignment scores/max scores and drop 3 scores to output the best percentage. The exact requirements can be found in my other thread: http://www.javaprogrammingforums.com...use-array.html

I ended up using an array to store the score and max score separately. My problem at this point is trying to come up with a way to drop 3 scores.

My code at this point is:

import java.io.*;
public class HW8 
{
	public static void main(String args[]) throws IOException
	{
	    BufferedReader keybd = new BufferedReader(new InputStreamReader(System.in));
 
	    double[] score = new double[31];
	    double[] max = new double[31];
 
	    System.out.println("Enter the amount of assignments: ");
	    int numAssign = Integer.parseInt(keybd.readLine());
 
	    if (numAssign < 4)
	    	{
	    		numAssign = 4;
	    	}
	    else if (numAssign > 30)
	    	{
	    		numAssign = 30;
	    	}
 
	    double result = 0.0;
	    double result2 = 0.0;
 
	    for (int i = 1; i <= numAssign; i++)
	    {
	    	System.out.print("Enter student's score #" + (i) + ": ");
	    	score[i] = Double.parseDouble(keybd.readLine());
 
	    	if (score[i] < 0)
	    		{
	    			score[i] = 0;
	    		}
 
	    	System.out.print("Enter max score #" + (i) + ": ");
	    	max[i] = Double.parseDouble(keybd.readLine());
 
	    	if (max[i] < 1)
	    		{
	    			max[i] = 1;
	    		}
	    	else if (max[i] > 100)
	    		{
	    			max[i] = 100;
	    		}
	    	if (score[i] > max[i])
	    		{
	    			score[i] = max[i];
	    		}
 
	    	result = result + score[i];
	    	result2 = result2 + max[i];
	    }	// ends for loop
	    	System.out.println("Original percentage: " + (result/result2)*100.0 + "%");
	}	// ends main
 
}		// ends class

I was thinking about using if/else conditions but that wouldn't really limit the amount dropped to 3. Any advice is appreciated!

Thanks for the previous suggestion! In my first post, I gave a link to another thread I made which had the actual requirements of the program on it. Basically the program is suppose to create the best possible percentage for a student by dropping 3 assignment scores. The score array and max array each store a score (e.g. 35 out of 40 possible points, score[i] stores the 35 and max[i] stores the 40). I had thought about putting them both into an array having the score and max alternate but wasn't sure if it was better to do. I felt that working with 2 separate arrays was easier to work with. Anyways, thanks again!
