如何折叠所有变量以提高代码可读性？

Question

In some my code i have a lot of variables. So to make it more readable i want to be able to fold them away so instead of this:

public class BIhcsAhuStartSeq_v2 {
    int counterVal_1 =0;
    int counterVal_2 =0;
    String clear="";
    String reset= "reset";

    public void test(){
        if(counterVal_1==1){setString(clear)}
    }
}

I want to do something like the below example so i can fold all variables away. How can i do this?

public class BIhcsAhuStartSeq_v2 {

    { 
    int counterVal_1 =0;
    int counterVal_2 =0;
    String clear="";
    String reset= "reset";
    }

    //example, but i cant acces the variables in the constructor ?
    public void test(){
        if(counterVal_1==1){setString(clear)}
    }
}

This has been asked several times here, on Stack Overflow.

Basically, the folding function implementation varies by IDE. For Eclipse, there was the Coffee-Bytes plugin to do custom (tagged), fold-able code blocks, but that has been abandoned.

Other mentions have been to use Jet Brains IDEA
