Run simple programs w/o making a new class in IntelliJ IDEA

I often need to run simple (one/two-line) programs to quickly get the output of a method I'm developing. However, to do so I need to create a new class, add a main method, and write the code there.

I was wondering if there is a simpler way to do this, because I do this quite often.

An example would be:

FormatHelper.format("\\1Does \\2This work?");

I know there needs to be some kind of context for a program to run (classpath, etc.), but I was thinking IntelliJ could handle it for me.

There is an IntelliJ IDEA plugin called Java REPL, which implements exactly what I was looking for.

The only downside (if you can call it a downside) is that you have to install a plugin

You should use http://ideone.com/ which is an online IDE.

Just write your one line code and hit run button

You can start the Groovy Shell from the Tools menu and run the expression there. Java expressions will work just fine.

This may not be exactly what you described, but check out this question: 'Immediate' window for IntelliJ

It appears to be related, and indicates that in IntelliJ 9 "There is ALT-F8 to evaluate an expression"

I just often hold a Test Class on a test package and do everything algorithm testing-related inside my main method there.

But to directly answer your question, AFAIK no IDE will do what you want.

On a side note, it may be worth trying ideone or compileonline
