Edit and run a .java file. How to do this?

[austin316]

Ok, I downloaded a .java file and added lines of code as was instructed. Now, when I try to run it, it won't see I need a main method. How do I go about doing this? I'm using JBuilder. Thanks in advance.

Are you trying to figure out how to compile the file? I am a little confused to what you are saying/asking. Can you clarify what you meant by this:

i downloaded a .java file. when I open the file I see all the code and everything. When I try to run it, it says I'm missing the main method. Usually when I run a java file I need to attach a class. I don't know how to do this with a program that I did not create myself.

can you post a link to the file? is this a sub class?

maybe the word I'm looking for is how to compile this .java file

assuming there are no errors in this file, you should be able to do

javac WrapperDemo.java

then to run it

java WrapperDemo


you will need to have the Java SDK installed for this to work...
