Explanation:
With a little more effort you can make the program allow the user to enter any number of details, but less than 30 overall. We have used here flag, and as a programmer we know why we use the Flag. It is used to check whether certain Boolean condition is fulfilled or not. Here, we are checking whether a given name is present in the array of names, and if it is not present, we add that to the list. And if the name is present, we print, it already exist.

double value;
String color;
public Ball() {
}
public Ball(double value, String color) {
this.value = value;
this.color = color;
}
public abstract void howToPlay();
}

The answer is Printer, workstation, NOC, and fax.
Any devices or systems connected to a network are called nodes. When defining a node, always have in mind that it is anything that has an IP address. For instance, if a network connects 5 computers, 1 file server, and 2 printers, there are 8 nodes on this network.
After a system is released and the user base grows, the demands on the development and support team will increase.
The development team can scale vertically by adding new people to the team.
