Answer Posted / vipin dhiman

in java default specifier is public but within the
samepackage.due to this property of public within same
package we have to define public before the main method
bcoz main has to be taken from jdk which is like the
different package. So if we want to anythig accessing to
the diffrent package we have to declare that with the
public keyword explicitly.

default constructor in java is same name of the class whose
object has to be declared.
example
class v
{
public static void main(String vip[])
{
System.out.println("i am vip");
}
in this default constructor is v();

as much as i know ,there is no concept of default method
