Should i format variables like this:

String type = null;
String name = null;
int age = 0;
double weight = 0;
boolean isFly;
boolean isWalk;
boolean isSwim;

Or like this:

String type = null, name = null;
int age = 0;
double weight = 0;
boolean isFly, isWalk, isSwim;

And may you give me any article about code formatting in java? Thanks for help!

>Solution :

As a professional Java developer I have always made variables like this:

String name = "Vitaly";

In my opinion it is the best way because it is easy to read and understand. However, there is no real functional difference so it is up to you. Hope this helps!
