An object is an runtime instance of a class in memory(i.e. RAM) A reference is nothing but a variable that stores the memory address of the object Consider the following example: MyClass ref = new MyClass(); In the above statement, the RHS i.e. new MyClass() creates an object and return it's memory; and the reference variable ref stores that address. You can check what address the reference variable ref stores by the statement System.out.print(ref)
