Question

In this assignment, you will create a letter (or email) from several sub-components. The subcomponents are reside in a hierarchy as follows.

Given the main program in the attachment (and below), create the necessary interfaces and classes to implement the rest of the program with the Composite design pattern.

public class Main {

public static void main(String[] args) {

String paragraph1 = "Lorem ipsum dolor sit... (long strings are shortened)";

String paragraph2 = "Curabitur eu laoreet ... (long strings are shortened)";

String paragraph3 = "Mauris eu mauris moll... (long strings are shortened)";

Paragraph par1 = new Paragraph(paragraph1);

Paragraph par2 = new Paragraph(paragraph2);

Paragraph par3 = new Paragraph(paragraph3);

LetterBody letterBody = new LetterBody();

letterBody.addComponent(par1);

letterBody.addComponent(par2);

letterBody.addComponent(par3);

Letter letter = new Letter("Test Letter", "Name Surname", "Test User");

letter.addComponent(letterBody);

letter.print();

}

}

At the end, the output of the program should look like below when you run the print method of the Letter class. Each line on each paragraph are wrapped at 80th column. If you are writing it in Java you can use WordUtils from Apache.
