I am creating a program with JCreator. The program code is mostly irrelevant to my question here, which is: Upon compiling I get only 2 errors: 1) "package javabook does not exist" and 2) "cannot access MainWindow" ... what do i need to do to get this thing to compile correctly? I know i need to do something with some sort of javabook.zip or javabook.jar file. However i only have the latter in my knowing posession. What's a jar file and what do i do with it? I have "import javabook.*;" at the begginning of the code for the class.
The basic code for what my program is is (most importantly) here: http://www.messiah.edu/acdept/depthome/mathsci/csc1812004-2005/Lab4/JavaProgs/BMIExample/Step4/BMICalculator.txt
and here: http://www.messiah.edu/acdept/depthome/mathsci/csc1812004-2005/Lab4/JavaProgs/BMIExample/Step4/BMICalculatorMain.txt
This whole instanciable class stuff very confusing, so hopefully that has nothing to do with this error.
ANY advice/teaching asap is greatly appreciated! Thanks
