The Code hints feature is as powerful.
Let's start with a simple example to illustrate the problem, such as in Eclipse, MyEclipse code, playing a foreach,switch, etc.

12. Go back to the MyEclipse interface, "File" → "Import", in the pop-up window select "Perferences", point
Click "Next", select the "TEST.EPF" file that has just been modified, click "Open", click "Finish". This step
Similar to the export steps above.
13. Finally, of course, the code is tested. Just create a new project and create a new class. In code input Switch,foreach etc.
To test. You'll find out immediately that there is a hint, and no matter which letter you hit, there are a lot of relevant hints, very streaming
Very convenient.
Summary: The "Auto Activation triggers for Java" option refers to the option to trigger the code hint and "." Change
