Hi guys, sorry for the question but i have a doubt is there an application as the one for windows named JCreator for mac to create java codes and running them right away
If you're interested in learning the language, rather than a tool, you should learn how to use the command line tools javac and java and a basic editor like jEdit.
Ryan suggested the use of lower level tools if the author was interested in learning the language. I just added ant because unless you like to use the bash history there is no point in typing all the java and javac options to build a project every time.
I use netbeans at work each day and like it for the most part. It does seem to randomly freeze up for 10-20 at a time rather frequently though, which is very very annoying. I haven't tried eclipse, I downloaded it and saw there was no easy way to import a project from netbeans so left it alone.
