The members of
Object
 are as follows:
The method
getClass
 returns the
Class
 ( 20.3) object that represents the
class of the object. A
Class
 object exists for each reference type. It can be
used, for example, to discover the fully qualified name of a class, its members,
its immediate superclass, and any interfaces that it implements. A class
method that is declared
synchronized
 ( 8.4.3.5) synchronizes on the lock
associated with the
Class
 object of the class.
The method
toString
 returns a
String
 representation of the object.
The methods
equals
 and
hashCode
 are declared for the benefit of hashtables
such as
java.util.Hashtable
 ( 21.7). The method
equals
 defines a notion
of object equality, which is based on value, not reference, comparison.
The method
clone
 is used to make a duplicate of an object.
The methods
wait
,
notify
, and
notifyAll
 are used in concurrent program 
ming using threads, as described in  17.
The method
finalize
 is run just before an object is destroyed and is
described in  12.6.
4.3.3   The Class
String
Instances of class
String
 ( 20.12) represent sequences of Unicode characters.
A
String
 object has a constant (unchanging) value. String literals ( 3.10.5) are
references to instances of class
String
.
The string concatenation operator
+
 ( 15.17.1) implicitly creates a new
String
 object.
