Restrictions for declaring a class in java

Restrictions for declaring a class in java :-

     A class never be declared by private and protected access specifier. i.e. If we do then we directly get compile time error.

-> When we declare a java class through public access specifier at that time file name must be match with the class name.

-> When we declare the java class through no access specifier at that time file name may match with the class name or may not.

* public class <class name>

  it will access in the same package and also different package.

* class < class name >

  it will access only same package not different.

* If we declare a class in private. 

private class X

{

 public static void main(String args[])

  {

   System.out.println("A class never be declare in private");

  }

}

* If we declare a class in protected. 

protecterd class y

{

 public static void main(String args[])

  {

   System.out.println("class never be declare protected");

  }

}
