Answer / harinath.b (sai sudhir p.g co
1) Object class is not an abstract class.The default
implementation is provided by javasoft.If we want we can
override the methods of Object class.
Ex class Top extends Object{
public String toString()
{
return "Java is ruling the WEB";
}
}
2)main() method is having the normal priority.To see how
it is :
class MainPriority{
public static void main(String main[]){
System.out.println("Main priority is
:"+Thread.currentThread().getPriority());
}
}
