Instructions If you think my puns are bad, you should check out boat names as you walk past any dock! Today, you are going to be working with some boat names that are docked at a local marina. Today's POD.java has been created for you. You are going to create a Sailboat class in Sailboat.java. POD.java makes use of the Sailboat class. You are going to write the Sailboat class in Sailboatjava You've been given an empty Sallboat class. Inside this empty class, you will create the fields, the constructor and write the toString() method to be used for output. The main method in POD.java has been written for you. It reads in boat names, instantiates the class Sailboat (multiple times), and then prints out the result using the toString() method. Details Input Create the following class fields: - string boatName: the name of the sailboat - counter counter: static value to be used within the class to keep track of how many dock spaces have already been used so far. - integer dockSpace: number of the dock space the sailboat will be assigned. When a new sailboat is brought into the marina (i.e. constructed), it will be assigned a dock space one greater than the one before it. Processing Create a Sailboat constructor: - The following input parameter is expected: - string: the name of the boat to be docked - Assign this boat name to the appropriate field - Increment the counter · Assign the new counter to the ȘdockSpaces field Create the toString() method for output (as below) Output The output is achieved by using the toString() method in the Sallboat.Java object class. It should be of the format BOAT-NAME is at dock space DOCK-SPACE Sample Input/output: Sample input (PoD.Java) Yeah, buoy! What's up dock?

Java.

Starter Code for PoD class:

import java.util.Scanner;

public class PoD {

public static void main( String [] args ) {


Scanner in = new Scanner(System.in);

final int MARINA_SIZE= 10;

String[] boatNames = new String[MARINA_SIZE];
Sailboat[] boats = new Sailboat[MARINA_SIZE];

int i = 0;

while (in.hasNextLine())
{
boatNames[i] = in.nextLine();
boats[i] = new Sailboat(boatNames[i]);
System.out.println(boats[i]);
i++;
}

System.out.print("END OF OUTPUT");
}
}

 

Other code for class Sailboat:

public class Sailboat

### Test Case Analysis #### Input of the Test Case ```plaintext 1. Yeah, Buoy! 2. Unsinkable 2 3. Vitamin Sea ``` #### Your Code's Output ```plaintext 1. Error: Could not find or load main class PoD 2. Caused by: java.lang.ClassNotFoundException: PoD ``` #### The Correct Output of the Test Case ```plaintext 1. Yeah, Buoy! is at dock space 1 2. Unsinkable 2 is at dock space 2 3. Vitamin Sea is at dock space 3 4. END OF OUTPUT ``` ### Explanation - **Test Case Input:** This section contains three lines, each specifying the name of a boat: 1. "Yeah, Buoy!" 2. "Unsinkable 2" 3. "Vitamin Sea" - **Your Code's Output:** This section shows an error message encountered during execution: 1. "Error: Could not find or load main class PoD" – indicates that the main class `PoD` could not be found or loaded. 2. "Caused by: java.lang.ClassNotFoundException: PoD" – the specific exception that caused the error, highlighting that the class `PoD` is not found. - **The Correct Output of the Test Case:** This section displays the expected output, which lists each boat's name followed by its designated dock space: 1. "Yeah, Buoy! is at dock space 1" 2. "Unsinkable 2 is at dock space 2" 3. "Vitamin Sea is at dock space 3" 4. "END OF OUTPUT" – marks the end of the output. ### Graphs or Diagrams There are no graphs or diagrams in this image. This exercise is focused on understanding the discrepancy between the actual and expected outputs in a coding context, specifically addressing a class loading issue in the error message. By correcting the issue pointed out in the error message (ensuring the `PoD` class is properly defined and accessible), the program should produce the correct output as listed above.
