Hi all,

 

Recetnly have been trying to learn Java and i started on a tutorial on sun. How ever i have a common problem and ive tried their solution and it doesnt work.

 

 

 

I compile my application into the .class then when i type in:

 

C:\java2\bin>java HelloWorldApp

 

 

 

i get the no class defination file.

 

 

 

I set the directory to the right place and it still says that.

 

 

 

Also my class file for somereason has become a java file that when i try to alter it into open with standard binary it says corrupt file. Any ideas on what i should do?

 

 

 

thanks

First of all, it's probably best to add javac[Caution: Executable File] (The compiler) to your environmental variables.

 

 

 

Second of all, your missing the extension. It outputs AppName.class

 

You have to run it using

 

java AppName.class

Typed in this:

 

C:\java2\bin>java HelloWorldApp.class

 

this came up: Exception in thread "Main" java.lang.NoClassDefFoundError: HelloWorldApp/class

 

 

 

whats with that?

i am taking a java class in high school so i can help you in about a school year lol

sorted the problem, java didnt recongnise the class directory, here is what i had to type

 

 

 

C:\java2\bin> java -classpath . HelloWorldApp
