What is the auto-alignment shortcut key in Eclipse?
Ctrl+Shift+F to invoke the Auto Formatter
Ctrl+I to indent the selected part (or all) of you code.
Auto-alignment? Lawful good?
If you mean formatting, then Ctrl+Shift+F.
The answer that the OP accepted is wildly different from the question I thought was asked. I thought the OP wanted a way to auto-align = signs or + signs, similar to the tabularize plugin for vim.
For this task, I found the Columns4Eclipse plugin to be just what I needed.
Want to format it automatically when you save the file???
then Goto Window > Preferences > Java > Editor > Save Actions
and configure your save actions.
Along with saving, you can format, Organize imports,add modifier ‘final’ where possible etc
