How do I configure Eclipse's code auto hints?

It is not easy for programmers to remember the names of a large number of class names or class methods. If you want the IDE to be able to automatically complement all the code, that will help our programmers a lot.

The Code hints feature in the Eclipse code is turned off by default and only the input "." Will be prompted, with VS users may be less accustomed to this, VS is to enter any letter will be prompted, below say how to modify the Eclipse configuration, turn on the code automatic prompt function to open the Eclipse-> Window-> perferences-> Java-> Editor-> Content Assist, find auto-activation in the bottom right column, with three options to find the second "auto activation triggers for Java:" option followed by You will see a "." in the text box. Exist.

This means that only the input "." Then there will be code hints and automatic completion, and that's where we're going to change it. Put the "." in the text box. Replace it and replace it with "abcdefghijklmnopqrstuvwxyz." So that you can write Java code in Eclipse and press "ABCDEFGHIJKLMNOPQRSTUVWXYZ." Any character in any of the characters will have code hints.

It's a great thing to quickly complete code when you're writing code with a few characters. But by default, Eclipse is only when you're typing '. ' (dot character), will pop up automatically fill the window to give you the choice. Most of the time it was completely inadequate.

Because eclipse itself has many options that are turned off by default, developers can only configure them manually.
