Ok , you want something like this:

Class StringProg has the 2 methods you require:

public class StringProg
{

    String s;
    int count = 0;

    //constructor
    public StringProg(String sIn)
    {
        s  = sIn;
    }

    //method to diplay string
    public void displayString()
    {
        System.out.println ("\nYour String: " + s); 
    }

    //method to find character
    public void findChar(char letter)
    {

        for (int i = 0; i<s.length(); i++) 
        {
            if(s.charAt(i) == letter)
            {
                count ++;
            }
        }
        System.out.println ("\nYour character " + "\"" + letter 
        + "\"" + " appeared " + count + " time(s)");    
    }

}

------------------------------------------------------
The second class tests the methods from StringProg:

public static void main(String [] args)
    {
        //the requested letter to find
        char letter = 'e';

        //create a StringProg object
        StringProg t = new StringProg("THE STRING GOES HERE");

        //display the string
        t.displayString();
        //search the string for a letter
        t.findChar(letter);


    }

---------------------------------------------------------

rickste_r,
Don't give out homework for free! They're never going to learn anything if you do it for them. There is nothing wrong with helping them, but DON'T do it for them!
And also, use the code tags around your code please

Thank you.
