At least 1 loop An Array or ArrayList At least 3 Java classes  Use methods I am trying to make it so that the program will: Prompt for the number of people included in exchange - If not even it will state that there has to be an even number and ask for the number of people included again (loops). Prompt to enter a participant's first name Prompt for the participant's age Print out the random matching of participants so that everyone gets a gift and everyone gives a gift.

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

Arrays of objects. Java programming: How to create and work with an array of objects in Java I wanted to know that supppose that I have 100 employees who are paid on an  hourly basis and I need to keep track of their arrival and departure times, and I have also created the class Clock to implement the time of day in a program.  I also know that I will use two arraays; one called arrivalTime and the other array called departure time. Each of these arrays will have 100 elements and each element will be a reference variable of Clock type.. For example Clock[] arrival =  new Clock[100]. My qeustion is how do I create the objects arrival and departure. Then how could I use the methods f the class clokc. Thank you

Recipe Program - Java ONLYI am looking to create a program that is a recipe holder. It needs to include at a minimum: At least 1 loop An Array or ArrayList At least 3 Java classes Use of methods The program would allow the user to (as part of a menu selection): Add a recipe Include ingredient list Instructions List all recipes that are in the program (array) Display a single recipe Search Recipes (option to view recipe selected) For example, searching for peanut butter cookie would bring up the recipe or multiple if the same name. The user could then select one of them to view the recipe. Search Recipes with a single ingredient (option to view recipe selected) For example: search for coconut and it would bring up coconut cream pie and German chocolate cake. The user could then select one of them to view the recipe. Close application Also need the program in a UML diagram.
