Eclipse shortcut to run a class

• Open the workspace preferences by the menu: Window > Preferences
• Select from the tree: Run/Debug > Launching
• Now the Launching preferences are seen.
• At the bottom there is Launch Operation
• Use the option Always launch the previously launched application

You can configure your launch behaviour so Ctrl-F11 will launch the last launched application again, regardless of your current editor selection.

Look at "Run/Debug" - "Launching" within the eclipse preferences.

Just use Ctrl + F11. (This is the standard keyboard shortcut to run the class you are working on)

I wish this is what you are looking for... buddy.
