On the lower level of Java, a "reference" can be thought of like a pointer in C. It is essentially an integer which refers to (points to) a location in memory where the object data exists.

// "button" is a reference to a JButton with a "1" on it (the object).
JButton button = new JButton("1");

Object occupies some memory to store all its members details . reference is like a variable having capability
to store the bits which gives us a way to access to stored object members.
