Quick project from .java file? [message #755538]

Here's the scenario: Someone sends me an email with a single Java file as an attachment. I'd like to open the file quickly so that it opens in Eclipse for running. I can set Eclipse as my default application for .java files, but then the file opens in Eclipse's editor **without** being in a project. Since the file isn't inside an Eclipse project, I can't run the file. Any suggestions?

Copy file contents and paste in Package Explorer.

Deepak,
By "Copy file contents and paste in Package Explorer" do you mean "Use the wizards to create a new Java class with the same name as the public class that's been sent to me and then copy the text from the the file into the newly created class (which is inside a project that I already created)?" If so, then I'm looking for a quicker way. With some very primitive IDEs I can simply do

./runIDE -sourcefile MyFile.java

and have the IDE be up and running, ready to execute the code. Is this possible with Eclipse? The extra steps (creating a project if necessary, creating or importing a class) seems like a lot of overhead for running a one-file Java program.

No. I meant copy the file contents, and go to PE (click somewhere in it
so that the focus is in PE) and press Ctrl+V (paste)
