Getting wrong answers for conversion

Question

Hi all,
I've been working on a program for base conversion.
After making some adjustments I am yet to get the "correct" answer for my conversion. For example when i key in 100 i get 10 as my answer.
I am using a label to set the text of my answer but all it does is take the number entered in the textfield i guess. Appreciate all replies.
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import java.io.*;
This is an applet that enables the user to enter the number and the base
system of number entered. Upon clicking the Convert button, the program should
display the number, the positional weightage of each digit of the number, and
the decimal equivalent of the number
public class Testing1 extends Applet implements ActionListener {
     //declare all components
     Label numbersystemLabel;  //Top Label
     Label numberLabel;  //Middle Label next to the number TextField
     Label baseLabel;  //Middle Label next to the base TextField
     Label answerLabel; //Bottom Label for the answer
     static String numberkeyin;  //number that is entered in the textfield
        static String bintype="binary";  //convert binary base to decimal
     static String octtype="octal";  //convert octal base to decimal
     static String yrtype="";
     static String real= "";
     TextField numberField;
     TextField baseField;
     Button convert;
     int Answer;
     Panel p1;
     Panel p2;
     Panel p3;
    public void init() {
         p1 = new Panel ();
         p2 = new Panel ();
         p3 = new Panel ();
         p1.setLayout(new BorderLayout(25,25));
         p2.setLayout(new GridLayout(2,2,2,2));
         p3.setLayout(new BorderLayout(25,25));
         numbersystemLabel=new Label ("Number System");
          p1.add("North",numbersystemLabel);
         numberLabel=new Label ("Enter the number : ");
           p2.add(numberLabel);
           numberField=new TextField(9);
           p2.add(numberField);
           baseLabel=new Label ("Enter the base system  ");
           p2.add(baseLabel);
           baseField=new TextField(9);
           p2.add(baseField);
           convert=new Button ("Convert");
           convert.addActionListener(this);
           answerLabel=new Label ("Decimal Equivalent : ");
          p1.add("South",answerLabel);
          p3.add("North",p2);
          p3.add("South",convert);
          p1.add("Center",p3);
          add(p3);
          add(p1);
  public void actionPerformed(ActionEvent event) {
     Answer=Integer.parseInt(numberField.getText());
     yrtype=baseField.getText();
     answerLabel.setText(real);
     if (yrtype.equals(bintype)){
       real="Decimal Equivalent: " +Answer  ;
    else {
       real="Decimal Equivalent: Daddy's girl ";
     repaint();
   private void Compute()  {
     int i;
     int countlength;
     char bit;
    Answer = 0; // initialize the answer to zero.
    countlength = numberkeyin.length();   
        // find the length of the binary number string.
        for( i=1; i<=countlength; i++) {
               bit = numberkeyin.charAt(countlength-i);
                // extract each binary digit, starting from the right.
               if( bit == '1' ) {
                    Answer += Math.pow(2.0,i-1.0);
   // The digit was a "1", so add it's decimal equivalent to the answer.
    public void paint(Graphics g)  {
     //power
     String a= "2" ; String v= "4";
     String b= "2" ; String w= "3";
     String c= "2" ; String x= "2";
        String d= "2" ; String y= "1";
        String e= "2" ; String z= "0";
       g.setFont(new Font ("Helvetica",Font.ITALIC+Font.BOLD,20));
       g.drawString("" +e +"     " +d +"     " +c +"     " +b +"     " +a, 350, 250 );
       g.setFont(new Font ("Helvetica",Font.ITALIC+Font.BOLD,12));
       g.drawString(" " +v +"           " +w +"            " +x +"            " +y +"            " +z, 355, 235 );
 

Answer 1

I think you need to completely re-think your
actionPerformed method. I don't think there's
anything correct in there.
I'm not going to do you homework for you.
Jeez, what's wrong with the people in here. I am not
asking anyone to do my homework for God's sake. Yeah
sure its a school assignment (what's the big deal
about that?)I just want to know the errors pertaining
to my code and ways on improving/correcting it.
Oh yeah,,, just knowing won't help. I have checked my
action Performed and i don't see anything wrong in
there though.
I am a newbie in java and would like to learn. So my
question is how can i call the compute method?
God save me from paranoids.Hi miss_mushroom...
If you look through these forums, you will find many "do my homework requests"...
so the replies here are understandable...
anyway here is an example code snippet...
public void sayHello(){
   System.out.println("Hello);//outputs "Hello"
public int doSomeMath(int num1,int num2){
/* returns an int and takes two ints as arguements\parameters */
   return num1 + num2; this is where the int get returned...
public void callMethods(){ // yet another method
   sayHello();// calls sayHello which displays "Hello"
   int answer = doSomeMath(10,5);//calls do someMath which adds 10 and 5
   // and the returned value is assigned to answer...
}many of your question can be answered by reading Sun's Java Tutorial...
