Classpath, Packages, etc.

[Claude Cundiff]

Hello everyone.

I'm going to try to keep this as brief as possible...

I'm having some issues understanding how to use multiple packages and set the classpath.

So far, I've only dealt with single source files. I've written two .bat files, one to compile and the other to run the program:

Compile Batch File
-----------------------------------------------
cd c:\
path javac c:\Java_Programs\Meaty.java
pause
run Batch File
-----------------------------------------------
cd c:\Java_Programs
java Meaty
pause

All the class files are in the following directory:
C:\Java_Programs

Hello Claude,

The following line in your compile .bat file isn't correct:

path javac c:\Java_Programs\Meaty.java

"PATH" is an environment variable in Windows. You set it to tell Windows where to look for executable programs. The Java compiler (javac.exe) is a program, and you need to tell Windows that it's in the bin directory where you installed the JDK. Step 4 of the JDK installation instructions explains how you should set the PATH.

When this is set correctly, you can compile your Java source code with the following commands:

c:
cd \Java_Programs
javac Meaty.java
