Eclipse common settings

1. Prompt key configuration

Generally, by default, the code prompt function of Eclipse and MyEclipse is much worse than that of Microsoft Visual Studio. Mainly, many options of Eclipse and MyEclipse are turned off by default, and developers must configure them manually. If developers don't know it, they don't know Eclipse. The code prompt function of MyEclipse can be as powerful as the code prompt function of Microsoft Visual Studio.

Let me first give a simple example to illustrate the problem. For example, in Eclipse and MyEclipse codes, you cannot get code prompts by calling foreach, switch, etc. (If you don’t believe me, try it yourself), let alone other things. In Microsoft You get very friendly code prompts in Visual Studio. In fact, the code prompt function in Eclipse and MyEclipse codes generally clicks "." by default. Generally, code prompts will appear only after clicking ".". Principle: The option "Auto Activation triggers for java" refers to the option to trigger code prompts. Changing "." to ".abcdefghijklmnopqrstuvwxyz(," means that when 26 letters and . are encountered, (these symbols trigger The code prompt function is now available. Enhance the code prompt function of Eclipse and MyEclipse. How to configure it specifically?

Let’s start with the steps:

1. Open MyEclipse, then "window" → "Preferences"

2. Select "java", expand "Editor", and select "Content Assist".

13. The last step is of course code testing. Just create a new project and create a new class. Enter switch, foreach, etc. in the code for testing. You will immediately find that there are prompts, and no matter which letter you type, there will be many related prompts. It is very smooth and convenient.

Summary: The option "Auto Activation triggers for java" refers to the option to trigger code prompts. Changing "." to ".abcdefghijklmnopqrstuvwxyz(," means that when 26 letters and . are encountered, these symbols will trigger code prompts. Function. Finally: It is best to change the pop-up time of the automatic prompt to less than 100 milliseconds, otherwise you will be finished before the automatic prompt pops up.
