Question

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());
}
}

Answer 1

Answer:

Couplet.java



public class Couplet extends Poem

{

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 extends Poem

{

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.getPoemName() +

" Lines: " + p.getLines());

}

}

Explanation:

The Couplet and Limerick classes should also be extended from Poem class. Also, in display method, you call getTitle(), however, it's written as getPoemName() in the Poem class. You need to change the name.
