Question
I need is an exception program to display the invalid page count message and save it as InvalidPageCountException. Java. Adapt the previous programs to use the Exception program. The output for the exception program should show all exceptions for all programs Novel, Novella, and Short Story. As well as the rest of the output. Right now it is only showing the exception for Novel and no other output.
BELOW IS THE CODE I ALREADY HAVE.
public abstract class Story
{
private String title;
private String authorName;
protected int numberOfPages;
private String message;
protected final int MIN_PAGES_IN_NOVEL = 101;
protected final int MIN_PAGES_IN_NOVELLA = 50;
protected final int MAX_PAGES_IN_NOVELLA = 100;
protected final int MAX_PAGES_IN_SHORT_STORY = 49;
public Story(String title, String authorName)
{
this.title = title;
this.authorName = authorName;
}
public String getTitle()
{
return title;
}
public String getAuthorName()
{
return authorName;
}
public int getNumberOfPages()
{
return numberOfPages;
}
public String getMessage()
{
return message;
}
public void setTitle(String title)
{
this.title = title;
}
public void setAuthorName(String authorName)
{
this.authorName = authorName;
}
public abstract void setPages(int numberOfPages)throws InvalidPageCountException;
public void setMessage(String message)
{
this.message = message;
}
public String toString()
{
String retString = ">>>Title: " + this.getTitle() + ", Author: " +
this.getAuthorName() + ", Number of pages: " + this.getNumberOfPages();
if (!this.getMessage().isEmpty())
{
retString = retString + " Note: " + this.getMessage();
}
return retString;
}
}
