Idea how to set the guide package without * sign

idea If not set The default more than 5 A class with the same package will become * Number ,

This is actually very easy to satisfy , And as the amount of code increases , We often don't notice the leading package code at the top .
When a class imports too many packages , It will often affect the starting speed of the whole project , Add cache .

So we should try to avoid this kind of import * Operation of No

The operation is as follows ：

Two values here , It means that when there are several identical guided packets, it will be converted to guided packets * package , Just make it bigger .

If this is set to 3, Like this ：

import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

At this time idea The compiler will automatically convert these three lines of code into ：

import java.net.*;

Here I set it to 999, This means that only when the same class under the same package is imported more than 999 Time , Will all be imported , Basically, import is completely avoided * It's possible
