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,the default specifier access the with in package
only.
EX:- public void setName(String name)
{
this.name=name;
}
The above method access any class or any package
void setName(String name)
{
this.name=name;
}
The above method can access with in package.

DEFAULT CONSTRUCTOR IN JAVA:-
THE default constructor in java is System default constructor.

EX:-
public class A
{
String name;
public void setName(String name);
{
this.name=name;
}
}
The above program their is no constructor .then that time
java compiler created default constructor.

Note: we can interested see default constructor frist we
compile java program(javac A.java) after javap A.Then that
time u watch system default constructor.

DEFAULT METHOD IN JAVA:--
The dafault method in java is super().
EX:-
public class A
{
A()
{
System.out.println("IAM CONSTRUCTOR FROM CLASS A ");
}
}
public class B extends A
{
B()
{
System.out.println("IAM CONSTRUCTOR FROM CLASS B");
}
public static void main(String k[])
{
B b=new B();
}
}
output:-
IAM CONSTRUCTOR FROM CLASS A
IAM CONSTRUCTOR FROM CLASS B
hence super() method is default method
