Hi! I'm somewhat new to Java, I've taken one year of Java and I think I got a good grip of it.

I'm looking to create a project that, once opened, will click an already opened internet browser in the start bar, then click around the screen every minute on a certain color programmed into the program.

Though, I have no idea where to start, any suggestions?

import javax.swing.*;
import BreezySwing.*;

public class ConvertWithGUI extends GBApplet {
	
	//Declare variables for the window objects.
	private JLabel fahrenheitLabel, celsiusLabel;
	private DoubleField fahrenheitField, celsiusField;
	private JButton fahrenheitButton, celsiusButton;
	
	//Init method - works like a constructor
	public void init(){
		//Instantiate and add window objects to the window
		fahrenheitLabel	      = addLabel	("Fahrenheit"	,1,1,1,1);
		celsiusLabel		= addLabel	  ("Celsius"	    ,1,2,1,1);
		
		fahrenheitField			= addDoubleField	(32.0				,2,1,1,1);
		celsiusField			= addDoubleField	(0.0				,2,2,1,1);
		fahrenheitButton		= addButton			(">>>"				,3,1,1,1);
		celsiusButton			= addButton			("<<<"				,3,2,1,1);
	}
	
	//Respond to button click events
	public void buttonClicked (JButton buttonObj){
		//Local variables
		Thermometer thermo = new Thermometer();
		
		//Determine which button was clicked
		if (buttonObj == fahrenheitButton){
			
			//Convert from Fahrenheit to Celsius
			thermo.setFahrenheit(fahrenheitField.getNumber());
			celsiusField.setNumber(thermo.getCelsius());
		}else{
			
			//Convert from Celsius to Fahrenheit
			thermo.setCelsius(celsiusField.getNumber());
			fahrenheitField.setNumber(thermo.getFahrenheit());
		}
	}
	//No method neccessary.
}

Then the thermometer class:

All of this runs in Eclipse.

Perhaps it's because when I try to open the ConvertWithGUI.class from My Computer it comes up with the message, "Java Virtual Machine Launcher: Failed to load Main-Class manifest attribute from C:\..."

The program was compiled and runs in Eclipse. When I try to add the <APPLET> tag into the HTML file, the applet doesn't show. It's just one white box, with a red X, and a grey boarder.

HTML code:

Is there some program that you must have to show the applets?

I found my problem and fixed it. I now have the whole GPAfinder program working.

Though, my last and final question is:

Is there a way just to open the GUI? Not open the whole project in Eclipse.

(The problem was..

Yet another trip up in the code. When the radio buttons are selected they arn't adding the .04 to the totalGPA, and it's not displaying the weightedGPA anywhere. I'm not sure if I have my privates, and publics mixed up or what. Or maybe I'm just positioning things wrong.

The whole code:

	private double S1block1Points;
	private double S1block2Points;
	private double S1block3Points;
	private double S1block4Points;
	private double S2block1Points;
	private double S2block2Points;
	private double S2block3Points;
	private double S2block4Points;
	private double coreGPA = 0;
	private double weightedGPA = 0;
	private double S1GPA;
	private double S2GPA;
	private double totalGPA;

Thanks alot! That worked. I did not remember the .equals thing, since it's been awhile since I've programmed.

and so on. Next, you do the work in processInputs() to calculate what S1block1Points is but then you never use that. Do you instead mean to use S1block1Points to set one of the text fields with a setNumber() call?

And yes, with all of my messing around trying to fix it, I forgot to re-add where S1block1Points outputs. Though it was in before.

Thanks again!

I know where the problem is. I've tested it out a few times trying to get around it, but there is something wrong with my initialization of the variable S1block1Points, or I do believe so atleast.

It's a GPA finder that I've been trying to create for personal use, I'm only partially into it and I'm getting this one annoying problem. Maybe you can help me and tell me why when I enter A into the TextField (which should give an output of 8 ) why I get an answer of 0?
