   • toString() method. The toString() provides a String representation of an object and is used to convert an object to a String. The default toString() method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object.
   • hashCode() method. For every object, JVM generates a unique number which is a hashcode. It returns distinct integers for distinct objects. A common misconception about this method is that the hashCode() method returns the address of the object, which is not correct.
   • equals(Object obj) method. It compares the given object to “this” object (the object on which the method is called). It gives a generic way to compare objects for equality.
   • getClass() method. It returns the class object of “this” object and is used to get the actual runtime class of the object. It can also be used to get metadata of this class.

If a class does not extend any other class then it is a direct child class of Object and if extends another class then it is indirectly derived. Therefore the Object class methods are available to all Java classes.
