Task 3 - Creating a simple console interface

Step 1

The method should perform the following actions:

• initialize the private field variable, which will be used as the internal model of the game,
• in a loop:
  • print the text representation of the game field to the console using the show() method,
  • read and process user input using the handleInput() method,
  • react to changes in the game state (FAILED, SOLVED, etc.).

Example implementation of the play method for the game Minesweeper:

public void play(Field field) {
    this.field = field;
    do {
        show();
        handleInput();
    } while(field.getState() == GameState.PLAYING);

    show();

    if(field.getState() == GameState.SOLVED) {
        System.out.println("Solved!");
    } else if(field.getState() == GameState.FAILED){
        System.out.println("Failed!");
    }
}

Step 2

For displaying the game field on standard output, the following requirements apply in the case of the game Minesweeper:

• Rows are labeled with uppercase letters in alphabetical order (A, B, ..., I).
• Columns are labeled with numbers (0, 1, ... , 8).
• To represent an uncovered tile (OPEN) of type mine (Mine), use the character X.
• To represent an uncovered tile (OPEN) of type clue (Clue), use the number representing the tile value.
• To represent a marked tile (MARKED), use the character M.
• To represent an unmarked tile (CLOSED), use the character -.

For tile-based games, we recommend proceeding in a similar way: define how the game field will be rendered (a two-dimensional matrix, a one-dimensional array printed horizontally or vertically, card games arranged according to players' positions or card layout rules). Then define the encoding of individual cells or cards using letters or special characters, similarly to the game Minesweeper: M, -, and numbers for clues.

The data needed to display individual tiles can be obtained from the game logic (in our case, the Field class instance).

public class Mine {
    @Override
    public String toString() {
        return "X";
    }
}

Step 3

In the game Minesweeper, the handleInput() method performs the following actions:

• Prints a prompt for entering input with the expected input format: X – end the game, individual moves such as MA1 – mark the tile in row A and column 1, OB4 – open the tile in row B and column 4.
• Reads the input from the user (nextLine()).
• Verifies the correctness of the input string using regular expressions.
• If the input is not in the required format, asks the user to enter it again.
• Performs the corresponding operation (mark tile, open tile, end the program) based on the identified user action.
