Question

Create a class named Tile that represents Scrabble tiles. The instance variables should include a String named letter and an integer named value. Write a constructor that takes parameters named letter and value and initializes the instance variables. Write a method named printTile that takes a Tile object as a parameter and displays the instance variables (letter and value) in a reader-friendly format. Using a Driver class create a Tile object with the letter Z and the value 10, and then uses printTile to display the state of the object. Create getters and setters for each of the attributes.

Answer 1

Answer:

Here is the Tile class:

class Tile {   //class name  

// declare private data members of Tile class

  private int value;  //int type variable to hold the integer

  private String letter;     //String type variable to hold the letter

  public void setValue(int value){  //mutator method to set the integer value

       this.value = value;    }

   public void setLetter(String letter){   //mutator method to set the letter

       this.letter = letter;    }

   public int getValue()   //accessor method to access or get the value

     {return value;}  //returns the current integer value

   

   public String getLetter()   //accessor method to access or get the letter

      {return letter;}     //returns the current string value

   

   public Tile(String letter, int value){   //constructor that takes parameters named letter and value

     setValue(value);  //uses setValue method to set the value of value field

     setLetter(letter);   }  }  //uses setValue method to set the value of letter field

/* you can also use the following two statements inside constructor to initializes the variables:

this.letter = letter;

this.value = value; */

Explanation:

Here is the driver class named Main:

public class Main{  //class name

public static void main(String[] args) { //start of main method  

           Tile tile = new Tile("Z", 10); //creates object of Tile class named tile and calls Tile constructor to initialize the instance variables  

       printTile(tile); } //calls printTile method by passing Tile object as a parameter

public static void printTile(Tile tile) { //method to displays the instance variables (letter and value) in a reader-friendly format

 System.out.println("The tile " + tile.getLetter() + " has the score of " + tile.getValue()); }  } //displays the string letter and integer value using getLetter() method to get the letter and getValue method to get the value

The screenshot of the output is attached.
