Pls Help...VERY URGENT

Question

Hi all,
I am unable to get a certain output from the code I have written: Below is the code.
public class project extends JApplet
     private JLabel promptLabel;
     private JTextField inputField,displayField;
     private JTextArea outputArea;
     public void init()
          Container container = getContentPane();
          String s1 = JOptionPane.showInputDialog("Enter a few alphabets");
          String.valueOf(s1);
          outputArea = new JTextArea();
          container.add(outputArea);
          outputArea.setText("The alphabets that you have entered are: "+s1);
I am suppose to get the output below:
The user will be prompted to enter a few alphabets.After the user clicks on 'OK' a java applet is suppose to popout with the alphabets the user has typed like in below. the user has to enter a message using the alphabets he gave(e.g abcd)
please enter a message using the alphabets entered:___________
a
b
c
d
I am unable to get the output.. I dunno how to go about getting the output above.. Another query, below is a Histogram class.
class Histogram
     int frequency[];
     String alphabet;
     Histogram(String alphabet)
          this.alphabet=alphabet;
          frequency=new int[alphabet.length()];
     void scan(String message)
          for(int i=0;i<message.length;i++)
               frequncy[alphabet.IndexOf(message.charAt(i))]++;
     void setfrequency(int frequency[])
          for(int i=0;i<alphabet.length;i++)
          this.frequency=frequency[i];
     double entropy()
          int total=0;
          double probablity;
          log2=Math.log(2.0);
          for(int i=0;i<alphabet.length;i++)
               total+=freguency[i];
If I want to get the frequency of each alphabet displayed in the applet, how do i go about implementing the setfrequency method in the java applet.. I hope some one can help me.. Pls it is very urgent.. Thanx

Hi Thanx, your code helped. I have got another question. How do i implement a method from another method class into the applet. say, i want to implemen set frequency from the below code into my applet you wrote above?
class Histogram
     int frequency[];
     String alphabet;
     Histogram(String alphabet)
          this.alphabet=alphabet;
          frequency=new int[alphabet.length()];
     void scan(String message)
          for(int i=0;i<message.length;i++)
               frequncy[alphabet.IndexOf(message.charAt(i))]++;
     void setfrequency(int frequency[])
          for(int i=0;i<alphabet.length;i++)
          this.frequency=frequency[i];
     double entropy()
          int total=0;
          double probablity;
          log2=Math.log(2.0);
          for(int i=0;i<alphabet.length;i++)
               total+=freguency[i];
