Create a class named Poem that contains the following fields: title - the name of the poem (of type String) lines - the number of lines in the poem (of type int) Include a constructor that requires values for both fields. Also include get methods to retrieve field values. Create three subclasses: Couplet, Limerick, and Haiku. The constructor for each subclass requires only a title; the lines field is set using a constant value. A couplet has two lines, a limerick has five lines, and a haiku has three lines.
Please correct so code works:
Couplet. java
public class Couplet
{
private final static int LINES = 2;
public Couplet(String poemName)
{
super(poemName, LINES);
}
}
Haiku. java
public class Haiku extends Poem
{
private static int LINES = 3;
public Haiku(String poemName)
{
super(poemName, LINES);
}
}
Limerick. java
public class Limerick
{
private static int LINES = 5;
public Limerick(String poemName)
{
super(poemName, LINES);
}
}
Poem. java
public class Poem
{
private String poemName;
private int lines;
public Poem(String poemName, int lines)
{
this. poemName = poemName;
this. lines = lines;
}
public String getPoemName()
{
return poemName;
}
public int getLines()
{
return lines;
}
}
DemoPoem. java
import java. util.*;
public class DemoPoems
{
public static void main(String[] args)
{
Poem poem1 = new Poem("The Raven", 84);
Couplet poem2 = new Couplet("True Wit");
Limerick poem3 = new Limerick("There was an Old Man with a Beard");
Haiku poem4 = new Haiku("The Wren");
display(poem1);
display(poem2);
display(poem3);
display(poem4);
}
public static void display(Poem p)
{
System. out. println("Poem: " + p. getTitle() +
" Lines: " + p. getLines());
}
}
