Calculating Values And Passing From Two-dimensional Array

Long story short: The program takes user values (temperature) and converts them to the opposite (C >> F / F >> C)

I originally started this program with three separate arrays but then decided that it would be a good opportunity to use a two-dimensional array and one other.

The two-dimensional array has 2 rows, 10 columns. The second is a normal String array ...

Java Code:

String[][] myTemperatures = new String[2][9];
String inputAssembly[] = new String[9]; mh_sh_highlight_all('java');

I prompt the user for to enter temperature values, using a GUI and jbutton to distinguish F/C. Each time the user clicks 'continue', the values are stored into the two-dimensional array. One row holds the temperature, the other holds the C or F designation.

Java Code:

// CONTINUE BUTTON CLICK ACTIONS
class ContinueButtonListener implements ActionListener{
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
input = view.getTempValue();

[Code] ....

This is where I am experiencing the trouble and I cannot seem to get the Debug to work properly here. When the two-dimensional array is full OR the user clicks 'calculate' instead of 'continue', the Calculate event is performed via an ActionListener.

Java Code:

// CALCULATE BUTTON CLICK ACTIONS
class CalculateButtonListener implements ActionListener{
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
String hold;
Double temp;

And I get a ton of errrors ...

Java Code:

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "[Ljava.lang.String;@7441b1fd"
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)

[Code] ....

I imagine the issue lies within how I am handling the two-dimensional array in the CALCULATE event and/or converting the String[][] to String then parsing to an Integer.

Would this be better done is separate arrays (not using one two-dimensional, but storing 34C, 45F ... in one. I think this would be difficult for me to parse for conversions).
