ive just written a class for my java program - where do i put the class file for my program to work? ? ?

Question

i tried running my little program after javacing both java files but it doesnt run - the class file is stored in the same folder - but i think it needs to go somewhere else.

hope someone can help.

Answer 1

If you used the default package (i.e., did not specify a package), then you just need to add that directory to your classpath.

So, if you used:

javac foo.java

.... to compile the program from the directory containing your java file, then you'd use:

java -cp . foo

... to execute it. Adding "." (current directory) to the class path ("-cp") will enable your class to be seen.

steps to run java prog.
1)Write your program on notepad and save it aslike
yourprog.java
2)Compile your program
on command prompt
c:/>javac path of yourprog.java

3)once compiled you can interpretate(run) it with
C:/>java path of your classfile.
note:: classfile might be different then your prog file
its the class which has main method.
there you go!!

still having problem
check whether you have set correct classpath or not.

hope this helps
Cheers:)

Hi,

You just can run a class file with the java executable from your java directory; for example: c:\your-java-dir\bin\java.exe YourClassFile; stated that you have a public static void main(String args[]) method. This method is being called when you just run your class-file.

Good luck!
