How to run Java scratch file in IntelliJ IDEA

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?

Solution

Executability for Java scratch files was added in IntelliJ 15, so you must upgrade for that feature.

You have several option how to run/debug the scratch file:

Click the icon next to the main method/class
Hit Control+Shift+R (Control+Shift+F10 on Linux/Windows) somewhere within the scratch file
Right click inside the method/class and select appropriate run/debug option
