Explanation:
The above snippet of code is used to create a class “CarlysEventPriceWithMethods”. In the code,
- Import the required header files.
- Define a class “CarlysEventPriceWithMethods”
- Declare the object of “Scanner” class.
- Define the “getEventNum()” method.
- Prompt the user to enter the event number.
- Return the value of “name”.
- Define the “getNoGuests()” method.
- Return the scanned value.
- Define the “displayMotto()” method.
- Print the values.
- Call the method “computePrice()”.
- Define the “computePrice()” method.
- Print the values.
- Define the “main()” method.
- Close the scanner.
b.
Event.java
//define a class Event
public class Event
{
//declare the class members
public final static int PRICE_PER_GUEST = 35;
public final static int CUT_OFF = 50;
private String eventNum;
private int noOfGuest;
private int price;
//define a method setEventNum()
public void setEventNum(String eventNum)
{
//set the value of eventNum
this.eventNum = eventNum;
}
//define a method setNoOfGuest()
public void setNoOfGuest(int noOfGuest)
{
//set the values of noOfGuest
this.noOfGuest = noOfGuest;
//set the values of price
