Naming convention for objects in Java

I had started programming in Java 2 years back. Seniors in our project at that time had advised me to append 'obj' to the name of the object which is being created.

Ex:

Car objCar = new Car("Ferrari");

Here objCar is what I am talking about. But many at Stack Overflow had opposed to it and now I find that this shouldn't be the way naming of an object should be done. I am clear with naming conventions when collections are used but I am confused when objects of general classes are created.

Can anyone shed some light on it?

What are the naming convention in Java?

Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter. Internal words start with capital letters. Variable names should not start with underscore _ or dollar sign $ characters, even though both are allowed. Variable names should be short yet meaningful.

What are the 3 rules for naming variables in Java?

Rules to Declare a VariableThe first character must not be a digit. Blank spaces cannot be used in variable names. Java keywords cannot be used as variable names.

Just call it car. Hungarian notation is not used by Sun/Oracle.

Name your variables in a manner which describes their use. But you don't need to indicate the type in the variable name. You already specified the type in the variable declaration. IDEs will show you the type of the variable if you mouse-over them so that information is always readily available.

You should use lowercaseStartingCamelCase for variable names and method names, and UppercaseStartingCamelCase for class names.

If you want to read how Sun/Oracle do things, you can read their Code Conventions for the Java Programming Language.
