Question

我一直致力于Noughts and Crosses的项目。我曾经遇到一个恼人的问题。当只有一个按钮被占用并且到目前为止没有检测到获胜动作时，作为一名玩家，我点击按钮，游戏应该提示它是平局。将出现一个对话框，单击“确定”后，将再次出现相同的对话框。在我看来，有一个无限循环。提前致谢

// make random move if above rules dont apply

Random rand1 = new Random();
Random rand2 = new Random();

int max = 2;
int min = 0;

int randnum1 = rand1.nextInt((max - min) + 1) + min ;
int randnum2 = rand2.nextInt((max - min) + 1) + min ;    

while( MadeMove == false) {
    while( true ) {

        if( !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.ComputerMark) && !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.PlayerMark))
        {
            SecondTest.cells[randnum1][randnum2].setText(SecondTest.ComputerMark);
            MadeMove = true; 

            if ( SecondTest.CheckDraw()) {
                break;
            }
            break;  
        } else {
            System.out.println("occupied");

            randnum1 = rand1.nextInt((max - min) + 1) + min ;

    }


    if ( GameDraw == true  ) {
        DrawCounts++;
        JOptionPane.showMessageDialog (null, "Oh no, it's a draw! " +
                " Total Player Wins : " + PlayerCounts + " " +

        jTextArea2.setText("It is a draw!\n To start a new game,please press Reset\n");
        gameOver = true;
        PlayerGame = false;
        AIGame = false;
        return true;
    }
    return false;

你的内循环有什么意义？当然，您想要随机尝试移动，直到MadeMove为真或检测到平局为止。您还希望在循环内移动随机数生成以减少重复。同样地将if和else中的draw的检查合并到一个检查中。这应该有效，除非随机移动获胜！

while( MadeMove == false) {
    randnum1 = rand1.nextInt((max - min) + 1) + min ;
    randnum2 = rand2.nextInt((max - min) + 1) + min ;

    if( !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.ComputerMark) && !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.PlayerMark)) {
        SecondTest.cells[randnum1][randnum2].setText(SecondTest.ComputerMark);
        MadeMove = true; 
    } else {
        System.out.println("occupied");
    }
    if (SecondTest.CheckDraw()) {
        break;
    }
}
