I just start using IntelliJ-14 and I want to know about a scratch file. If I create a java scratch can I compile this as a normal Java class. What I Have Already Tried Create a Java class in a scratch file but unable to find any way to compile this. What I am looking for rather than creating a new Java file in an existing project for running some test code I just want to use scratch file and write some test class with the main method and after complete running close the scratch file. Is that possible?
