If I write lambda parameters with types, no auto complete:

Step 1: Open your Eclipse or Spring Tool Suite, then go to the Window > Preferences as shown in the below image. Step 2: In the next screen go to the Java > Editor > Content Assist > Auto activation triggers for Java as shown in the below image.
you type the first letter/letters and when you click ctrl + space you get a list of all the variables that start with that letter/letters. it's an auto-complete tool...
The following fixed it: Open Eclipse Preferences. Go to Preferences > Java > Editor > Content Assist > Advanced. Make sure that Other Java Proposals is selected in the list of proposal kinds.
Yes, this is a known bug of Eclipse, which has not yet been fixed: Eclipse bug 460921.
