Answer:
which type of questions is this
Answer:
Host discovery
Explanation:
Hot discovery is one of the preliminary stages of network reconnaissance, it begins with different IP addresses that belongs to a particular network and adopts various methods to scan and know if a host is at the IP address. Host discovery is also known as ping scan when a sonar analogy is used.
Host discovery helps to scan the particular type of host on one's network.
package mypackage; // Whatever package this should be in.
public abstract class DesktopComponent {
private String type;
// Alternatively you may want a final variable.
// private final String type;
public DesktopComponent(String type)
{
this.type = type;
}
abstract void onClick();
}
Answer:
Encapsulation:-It is the binding of the data and functions so that they works as one unit.
Inheritance:-When one class acquires the property of another class it is called inheritance.
Polymorphism :-It generally means more than one form
Explanation:
Encapsulation:- class is an example of encapsulation it can hold different data types and functions in a single container called class.
class Name{
public:
string first_name;
string last_name;
void Display()
{
cout<<first_name<<" "<<last_name<<endl;
}
};
Inheritance:-The property of a class acquiring the properties of another class is called inheritance.
Now we will inherit the above defined class.
class person: public Name
{
public:
char gender;
int age;
void Display()
{
cout<<first_name<<" "<<last_name<<gender<<age<<endl;
}
};
int main()
{
Name n;
person p;
n.Display();
p.Display();
}
Polymorphism- There are two types of polymorphism:-
1.Run time polymorphism=The values are decided at run time.
2.Compile time polymorphism=The values are decided at compile time.
Example:-In the above example we have function Display() in both the classes.This is an example of compile-time polymorphism. We are deciding at the time of compilation which display to use.
