Provide a class called Letter for authoring a simple letter. The letter class has three data fields, the name of the sender, the name of the recipient, a body of the letter.
1. Supply the class constructors (default , and overloaded )
2. Supply a method.
Public void addLine (String Line)

To add a line of text to the body of the letter
The addLine method should through an exception if the line is empty.
3. Supply a method.
Public String getText()

That returns the entire text of the letter.The text has the form :
Dear recipient name:
Blank Line
First line of the body
Second line of the body
…
Last line of the body
Blank line
Sincerely,
Blank line
Sender name
4. Also supply a program LetterPrinter that asks the user to enter lines of text nd verifies that the lines are not empty and prints the following letter :
Dear teacher:
Line supplied by the user
Line supplied by the user

Sincerely,
Student name
