Members marked public are accessible to members of any class
irrespective of the package.
Members marked private are only accessible to other members
of the same class.
Members marked protected are only accessible to other
members of the same class, members of a subclass and members
of other classes in the same package.
Member marked static are shared by all instances of that
class and hence r not related to any specific instance of
that class. Methods marked static cannot access non-static
members or fields of that class. But non-static members can
access static fields or methods.
a method or field defined by public is accessible by all
other methods and fields of that program anywhere.
u can't access the private members or methods outside the
class they are only accessible inside the class.
eg: if u have "org.iitk.ankit.abc.java;" and another file in
the package "org.iitk.ankit.xyz.java;".
in this case u can't access the private methods of abc.java
class in the xyz.java file's calsses.
in case of protected u can access the protected members in
the same package but can't access outside that package.
eg: means u can access members of abc.java in xvz.java.
b'coz they are in the same directory.
but not accessible in iitk directories files.

public void add()
public static void main(String args)
Garbage obj=new Garbage();
Above is a code in java used for garbage collection. object
obj has been created for the class Garbage and system.gc
