tl;dr;fmoe. I came across the same question in a review exercise found within Cay Horstmann, Big Java, Early Objects (John Wiley & Sons, 2013), 73. Cay defines an object variable as a variable (whose type is a class) which stores a reference to the memory location of an object.

Java is a pure object oriented language means everything we discuss in java is an object. Objects represent the state and behavior of class. Object is just a memory area or a buffer in heap area in which all the instance data members are getting a memory. In Java “new” operator is only used for allocating a memory for an object only. Memory associated with object is automatically collected by garbage collector. $ javac ReturnObjectExample.java $ java ReturnObjectExample Object #1 Side: 10.0 Volume: 1000.0 Object #2 Side: 10.0 Volume: 1000.0 So, in the above example we have the Cube class and we are setting the side of the cube via the constructor.

The general contract of hashCode() states:. Whenever it is invoked on the same object more than once during an execution of a Java application, hashCode() must consistently return the same value, provided no information used in equals comparisons on the object is modified.

Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object's data as well as information about the object's type and the types of data stored in the object. A class must have a matching filename (Main and Main.java). Using Multiple Classes Like we specified in the Classes chapter , it is a good practice to create an object of a class and access it in another class.
