Now you can arrange your files like a pro by using your own packages to clean up your class files. The following tutorial explains the steps necessary to accomplish this.
Have you ever wanted to clean up a folder FULL of .class files, and sort them into folders based on their use? Perhaps you have simply wanted to put the program into a folder so all that is visible is a single .exe, or .bat, or .java. Here are the required steps:
All you need is a few lines. In the example below, these class files are used:
1) program.java
2) GUI.java
3) run.java
Suppose I want to put program and GUI into folders based on their use and leave run at the same level as these folders.
I will assume that GUI and program do not need to know about each other, and run needs access to both.
Ending File Heirarchy:
GUI.java
program.java
run.class
run.java
PROGRAM <--this is a folder
|
---------program.class
GUI <----this is a folder
|
-----------GUI.class
NOTE: As long as you do not wish to modify a .class file, AND it is not needed to run your program, the corresponding .java file is not necessary and can be deleted.
To accomplish this, do the following:
GUI.java:
This is used as the first line, and it MUST be the first line of any class.
Then add the following line:
Package GUI;
*Now compile, and the folder GUI will be created with the GUI.class file inside it.
program.java:
Use this as the first line, and it MUST be the first line of any class.
Add the line:
Package Program;
*Now compile, and the folder Program will be created with the program.class file inside it.
run.java:
We must now tell this file where to find the .class files we just moved.
Simply add the following to the rest of your imports:
import GUI.*;
import Program.*;
NOTE some compilers do not like the * operator on personal packages, and you may have to do the following:
import GUI.GUI;
import Program.program;
The .class files will still be listed inside the original folder, but I assure you they are no longer needed.
Compile run. java, and you are done.
