Answer:
public class Invitation
{
private String hostname;
private String address;
public Invitation(String n, String a)
{ // constructor that accepts two strings.
hostname = n;
address = a;
}
public String getHostname()
{
return hostname;
}
public void setAddress(String a)
{
address = a;
}
public String invite(String guest)
{
return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";
}
public Invitation(String host, String address)
{
this.address = address;
this.hostname = host;
}
}
Explanation:
The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.
Network topology is the arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks.
Advantages:
It is easy to handle and implement.
It is best suited for small networks.
Disadvantages:
The cable length is limited. This limits the number of stations that can be connected.
This network topology can perform well only for a limited number of nodes.
