Hi Everyone,
I am new to SCJP 5.0. I have problem in classpath.
The problem is:
I have dclared an interface and class implementing it as below:

interface A
void go();
class C impelements A
public static void main(String[] a)
C c=new C();
public void go()

I have set the path as C:\jdk\bin in the Environment variable setting.
I have created two directories under C:\ as C:>SUN\SUN1. I have saved the file in the directory SUN1. I want to set the classpath from command-line so that I will be able to access and run
Please help me in setting classpath properly so that I can compile and run from C:\> prompt by correctly specifying classpath.

With Best Regards!
Sunil Kumar,
SCJP Aspirant.

For setting environmental path do the following
1)Go to the Bin folder of Java installation folder
2)Copy it in the environmental variables and add something like..

C:\Program Files\Java\jdk1.6.0_02\bin;%path%;.

And then your JDK tools will run anywhere.
There will be no need of explicit classpath setting.

For setting classpath use:

set classpath=path
where path can be:
"." if your source code is in current location
else mention the path
