1) YES, you can use the methods of a class without creating an instance or object of that class through the use of the Keyword "Static".

2) If you declare the method as "Static" then you can call this method by :

                *ClassName.MethodName()* 

3) E.g.

class Hello {

   public static void print()
   {

     System.out.println("HelloStatic");
   }  

}


class MainMethod {
    public static void main(String args[])
    {
       // calling static method
       Hello.print();
    } 
}  

4) The output of the above program would be : HelloStatic
