I have to Write a program which takes a series of 10 grades that students have gained for a coursework exercise (characters taken from A, B, C, D, E or F), typed in by the user. It should keep a count of how many of each grade the students achieved. These counts should be stored in an array of size 6, with cell 0 of the array holding the total number of As, cell 1 holding the total number of Bs, cell 2 holding the number of Cs etc.

I can do all the arrays and everything but sorting is a problem, If you look at the code you will see where i am stuck.

import javax.swing.JOptionPane;

public class Unit10Dem2
{
public static void main(String[] args)

{
String[]grades=new String[6];
String input;

int count=1;
for (count=1; count<=10; count++)
{

input=JOptionPane.showInputDialog("Please enter a students grade");
if (input=="a")
{
grades[0]=new String("a");
}
System.out.println(grades[count]);
}
}
}

Any advice please?
