Coffee is one of the most popular drinks in the world and coffee shops are becoming increasingly popular. A coffee shop in the United States has created a drink order class in order to streamline the process of ordering coffee. The class allows customers to choose their drink, size, flavoring, and extras. The class also allows the coffee shop to keep track of drink orders and ensure that they are fulfilled correctly. This is a great example of how coffee shops are using technology to improve the customer experience.

Which of the following best describes the relationship between a class and an object?
A class defines the attributes and behavior of an object. Every object that is created from a class will have the same attributes and behavior as defined by the class.
Numerical data is very important in business because it can provide valuable insights into things like average salary, maximum salary, average employee age, etc. This data can help businesses make informed decisions about things like employee compensation and hiring.
What is the correct syntax for creating a scanner object
The correct syntax for creating a Scanner object named kb is: Scanner kb = new Scanner(System.in);
The keyword return is required in all non-void methods. This is because the method sum has a return type of int and the return line is required to return a value of this type.
What is the relationship between classes called?
There are several different types of relationships that can exist between two classes. The most common type of relationship is a simple association, which is a relationship between two classes that does not involve any special semantics. Another type of relationship is an aggregation, which is a relationship between a class and its parts. A third type of relationship is a composition, which is a relationship between a class and its parts that is stronger than an aggregation.
An object is a member or an “instance” of a class. A class is a template for objects. It defines object properties including a valid range of values and a default value. It also describes object behavior.
What data type is used for MONEY?
The money data type is an abstract data type that is used to store values in currency units. Money values are stored significant to two decimal places. These values are rounded to their amounts in dollars and cents or other currency units on input and output. Arithmetic operations on the money data type retain two-decimal-place precision.
Employee data is a collection of information that pertains to individual employees within a company. This data can include everything from an employee’s name and contact information to their job title and salary. Employee data is typically maintained by the HR department and is used for a variety of purposes, such as keeping track of employee performance, administering payroll, and managing employee benefits.
What type of data is employee data
Employee data is essential to businesses in order to make informed decisions about their team. This data can be used to assess employee performance, understand engagement levels, and identify retention risks. By tracking employee data, businesses can develop strategies to improve their workplace and overall functioning.
The Scanner class is a simple text scanner that can parse primitive types and strings using regular expressions. A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.
How do you write characters in a Scanner?
You can use the Scanner class to take a character input from the user using the next() method. For example, the following two lines of code would take a character input from the user and store it in the variable ‘a’:
Scanner input = new Scanner (System.in);
char a = input.next().charAt(0);
Here, we are asking for a string input through the nextLine() method of the Scanner class. The input is then stored in the ‘name’ variable and printed to the console.
Do you need a return in a void method
Any method declared void doesn’t return a value. It does not need to contain a return statement, but it may do so.
Void functions are never guaranteed to return anything, so it’s best not to use them if you’re expecting a value. Non-void functions, on the other hand, always return a value (even if it’s just 0), so you can be confident that you’ll get something back from them.
Can you return nothing in a void method?
A void function cannot return any values. But we can use the return statement to increase the readability of code. The return statement indicates that the function is terminated.
Has-a relationship is when a class has a field whose type is another class. For example, a Person class can have a field whose type is an Address class. This relationship is also known as composition.
Is-a relationship is when a class is a subclass of another class. For example, a Person class can be a subclass of an Animal class. This relationship is also known as inheritance.

A coffee shop has created a DrinkOrder class to manage customer orders. The class has the following member variables:
– a String to hold the type of drink being ordered
– an int to hold the number of drinks being ordered
– a double to hold the price of the drink order
The class has the following methods:
– a constructor to initialize the member variables
– a setType method to set the type of drink being ordered
– a setNumber method to set the number of drinks being ordered
– a setPrice method to set the price of the drink order
– a getType method to return the type of drink being ordered
– a getNumber method to return the number of drinks being ordered
– a getPrice method to return the price of the drink order
– a toString method to return a String representation of the drink order
A coffee shop has created a drink order class in order to help customers make choices about their drink orders. This will help to ensure that customers receive the drink they want, and that the coffee shop can keep track of customer orders. This will also help to speed up the ordering process, as customers will not need to worry about making choices about their drink order.
