1. Set full eclipse characters CodeAuto-completion
1. "window" → "Preferences"
2. Select "Java", expand, "Editor", and select "content assist ".
3. Select "content assist" and then see the "auto activation triggers for Java" option under "auto-activation" on the right. In fact, it refers to the "." symbol that triggers the code prompt.
4. Add the abcdefghijklmnopqrstuvwxyz letter after "auto activation triggers for Java" to facilitate later search and modification. Then, "Apply" and click "OK ".
2. Modify the Code Completion shortcut
The shortcut key for completing eclipse code is Alt +/by default. I am not used to it anyway. I am used to Shift + [space] to activate code completion.
Open the windows> preferences> General> keys menu item, enter "content assist" in the filter box above, select the content ASSIST project, and specify a new shortcut in the binding editing box below.
