Calculator will not answer new problems - java

The calculator I am working on will solve the first problem perfectly, but when add is hit a second time, the answer moves closer to the addends and both the addends and the sum remain the same. Can anyone shine some light on what is making my program act this way? Thanks!

Can I set array in class from inside action listener? JAVA

Basically all I need to do is get array1 and array2 from each of my buttonlisteners and I have no clue how to do this as it is.. Right now the TextMatch button doesn't work because array1 and array2 are empty, is there a way to set them from the buttonlistener classes?
All I need is a way to set array1 and array2 as ss and sstwo so I can implement my TextTools.match() method

double value = token.count();
length1 += value*value;
}
length1 = Math.sqrt(length1);
for(SuperString token : Y)
{
double value = token.count();
length2 += value*value;
}
length2 = Math.sqrt(length2);
double total = 0;
int j=0;
for(int i=0;i<X.length;i++)
{
while(j < Y.length && X[i].compareTo(Y[j])>0 )
j++;
if(j == Y.length)
return total/(length1*length2);
if(X[i].compareTo(Y[j]) == 0)
total += X[i].count()*Y[j].count();
}
return total/(length1*length2);
}
}

Turns out I'm erasing over my array1 and array2 by re declaring SuperString in the actionlistener

Checkbox Compilation Error

I am to stimulate a java applet of a menu with checkboxes and checkboxgroups, with calories listed next to each food choice. My problem is I cannot figure out why I keep getting this error message when i compile it:
AnAppletWithCheckboxes.java:188: illegal forward reference
int crepeVal = Integer.parseInt(textField.getText());
I get that for every line that I have is converting the textField into an int, so hence there are 17 errors. Any idea of why will be appreciated!
Here is my Code:: it is very long because there are plenty checkboxes and textFields. I commented Out My place of Error! :

In Java, you are not allowed to refer to a field a in an initializer of another field b if b is declared before a in the source code. That is, this is allowed:
int b = 3;
int a = b;
but this is not allowed:
int a = b;
int b = 3;
By the way, if Java had some magic way of figuring out that textField had to be initialized before crepeVal, you would still get a NullPointerException since textField is null after object construction.

GRADING SYSTEM using JComboBox for the entry of grades; Jlabel, JTextFirld,JFrame; JButton for events; all in JFrame

here is my code for our finals. a grading system were the grades are all in 24 JComboBox. some with numbers till 10, 20 and 30. each quarter they are computed and shown in a JTextfield. when the four quarters are complete a Jbutton "COMPUTE ALL" calculates the entire data and will show in another frame the student's grade and weather he or she have passed or failed. this code works good with some problems: (1) my Jbutton "CLEAR ALL" doesn't work. it should show the default number "0" when clicked and the Jtextfields must be empty-(THIS ALREADY WORKS "TEXTFIELD TO EMPTY". (2) i want to hide the second frame when the Jbutton for compute all is clicked (f2.hide();f3.show();) but it keeps saying (cannot find symbol
symbol: variable f2cannot find symbol) (3) and lastly in my 3rd frame where the student's final grade and final rating are shown i cant really have it shown in a message dialog stating weather he or she passed or failed. THANKS. sorry for the poor coding.

These were the problems,
1.When you give zero in quotes like "0" its taken as string, whereas Integer is what required.
2.The jFrame f2 was not accessible because it was defined inside another action event.
3.The same was the problem with the variable equiv, thats why it was not accessible in the event of jOptionpane.

Write to text file through a java GUI

I have created a java GUI that works as a 6-question questionnaire. For each of the six question, I have 4 choices , i, ii, iii, iv for the user to choose, and then type out one of the four choices in a text box, then click a button "enter" to go to the next question. After all six questions have been answered, it will jump to a finish page.
I want to write the input value (in the text box) of each question to a text file. So After clicking on the "enter button" to answer all six questions I can see something like "i ii iii i ii iii" in a text file.
Is there a way to do it?
Here is my code:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class HTML extends Applet implements ActionListener
{
private TextField question;
private Button enter, start;
