私は Java を初めて使用し、単純なタスク (TicTacToe コンソール ゲーム) に取り組んでいます。while今日、doループ後に main メソッドを続行できないという問題に直面しました。プロジェクトには と の 2 つのクラスがMainありFieldます。Field は、すべてのゲーム フィールドの更新に応答します。メイン メソッドの do while ループでメソッドを呼び出しFieldていますが、結果がループにある場合は終了し、メイン メソッドを続行する必要があります (ユーザーがもう一度再生するかどうかを確認する必要があります)。while残念ながら、プログラムは doループ後に停止します。
これが私のコードです：
import java.io.IOException;
import java.util.Scanner;
public class Main {
private static char playerSym, compSym;
private static int Sym;
public static int playerChoice;
public static boolean result;
public static void main(String args[]) throws IOException {
Field field = new Field();
// start of the game
System.out.println("Let`s play");
System.out.println("Choose your symbol please");
System.out.println("0='O', 1='X'");
Scanner sc = new Scanner(System.in);
Sym = sc.nextInt();
while (Sym != 0 & Sym != 1) {
System.out
.println("The symbol you entered is incorrect, please repeat");
System.out.println("0='O', 1='X'");
Sym = sc.nextInt();
}
// setting player character
if (Sym == 1) {
playerSym = 'X';
compSym = 'O';
} else if (Sym == 0) {
playerSym = 'O';
compSym = 'Х';
}
System.out.println("There is a game field");
System.out.println("Please choose the cell number you`d like to fill with " + playerSym);
field.firstShowFields();
do {
playerChoice = (Integer) sc.nextInt();
field.updateFields(playerChoice, playerSym);
field.showFields(field.fields);
} while (result==false);
System.out.println("Want to play once more? Y-Yes, N-No");
char answer = (char) System.in.read();
switch (answer) {
case 'Y':
System.out.println("Restarting the game");
break;
case 'N':
System.out.println("Thank you! Bye-Bye!");
break;

break;
}
}
