DEFAULT SPECIFIER IN JAVA:
There are 4 types of accessibility specifier in java, they
are private,public,protected and default.
There is no key word in java to specify default specifier
When we do not specify any specifier which means default
specifier,

For Example :
public String getName(){...}
// here accessibility specifier is public

String getName(){...}
// here accessibility specifier is defalut, whose scope
is package-scope means this method is not accessible outside
the current package

DEFAULT CONSTRUCTOR IN JAVA:
Default constructor is the implicit constructor provided by
the compiler when we do not specify any constructor in our class
Default constructor looks like..
---------------------------------
<Access Modifier> <class_name>(){
super();// implicit super call
}

I have not heard about any default method in java..As far my
knowledge there is no default method till JAVA platform 1.4....
