You are creating a console application named App1.
App1 will validate user input for order entries.
You are developing the following code segment (line numbers are included for reference only):

You need to complete the code segment.
The solution must ensure that prices are positive and have two decimal places.
Which code should you insert at line 03?

HOTSPOT
You define a class by using the following code:

You write the following code for a method (line numbers are included for reference only):

To answer, complete each statement according to the information presented in the code.

You have the following code (line numbers are included for reference only):

You need to ensure that if an exception occurs, the exception will be logged.
Which code should you insert at line 28?

You have the following code:

You need to retrieve all of the numbers from the items variable that are greater than 80.
Which code should you use?

You are creating a console application named Appl.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):

You need to ensure that the code validates the JSON string.
Which code should you insert at line 03?

You are evaluating a method that calculates loan interest- The application includes the following
code segment. (Line numbers are included for reference only.)

When the loanTerm value is 3 and the loanAmount value is 9750, the loanRate must be set to 8.25
percent.
You need to adjust the loanRate value to meet the requirements.
What should you do?

You are implementing a new method named ProcessDat
a. The ProcessData() method calls a third-party component that performs a long-running operation.
The third-party component uses the IAsyncResult pattern to signal completion of the long-running
operation.
You need to ensure that the calling code handles the long-running operation as a
System.Threading.Tasks.Task object.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

You are developing an application for a bank. The application includes a method named ProcessLoan
that processes loan applications. The ProcessLoan() method uses a method named CalculateInterest.
The application includes the following code:
You need to declare a delegate to support the ProcessLoan() method.
Which code segment should you use?

You are modifying an application that processes loans. The following code defines the Loan class.
(Line numbers are included for reference only.)

Loans are restricted to a maximum term of 10 years. The application must send a notification
message if a loan request exceeds 10 years.
You need to implement the notification mechanism.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

An application contains code that measures reaction times. The code runs the timer on a thread
separate from the user interface. The application includes the following code. (Line numbers are
included for reference only.)

You need to ensure that the application cancels the timer when the user presses the Enter key.
Which code segment should you insert at line 14?
