java help needed

[mayhewj7]

- i have an assignment to create a text grid. the system will allow the user to specify a row and column in the grid, and specify the character to be placed in the cell. after each modification the grid will be redisplayed.

-must use a 2D array
-it must consist of 3 classes including the driver
-each time the system starts it should start with a blank slate
-and each the user modifies the grid it should ask if they wont to do another modification or exit.

This is what I have so far. i need some help to finish this thing up. If anyone could help i would greatly appreciate it. thanks



public class Cell{
private char letter = ' ';
private int row;
private int column;

public Cell(){
this.row = 0;
this.column = 0;
}

public void setLetter(char _letter){
this.letter = _letter;
}

public char getLetter(){
return this.letter;
}

public void setRow(int _row){
this.row = _row;
}

public int getRow(){
return this.row;
}

public void setColumn(int _column){
this.column = _column;
}

public int getColumn(){
return this.column;
}
}

this.option = 1;
this.cells = new Cell[rows][columns];
for(int r = 0;r<this.cells.length; r++){

Cell cell = new Cell();

this.rows = sc.nextInt();

System.out.println("Enter a letter: ");

System.out.println("Press 1 to modify or 2 to exit ");


}
}
}

Change class Cell to Cells. This class should have an instance property

private char[][] cells = null;

public Cells(int rows, int columns) {
cells = new char[rows][columns];
// Loop through the rows and columns to set each array entry to ''
}

Add methods

char getCharAt(int row, int column) {...}
void setCharAt(int row, int column) {...}

Your driver class will need access to the CellInterface methods, so make them at least default.

Don't put the prompt for rows, columns logic in the CellInterface constructor. Create a getSetup() method that returns the rows and columns in an int[2].

CellInterface needs methods

int[] getSetup()

char promptForChar()

void displayValues(char[][] chars)

CellDriver should have a main(). Have it create an instance and invoke the instance's run() method.

The constructor need not do anything.

public void run() {
// put your driver logic here
}

1. Prompt for the setup
2. Prompt for cell values, one at a time, until null is returned
3. Display the values
