有沒有更好的方法可以將所有這些都放在一個數組中？

Question

我是一個初學者，想制作一個剛開始的國際象棋游戲我認為有更好的方法，但是數組中的所有部分都不需要像這樣寫每個部分我的代碼太長太丑請幫助我

public class Chess {
    public static void main(String[] args) {
        int [][] grid = new int[8][8];

        Pieces PB1 = new Pieces(); PB1.Pieces = 6;
        Pieces PB2 = new Pieces(); PB2.Pieces = 6;
        Pieces PB3 = new Pieces(); PB3.Pieces = 6;
        Pieces PB4 = new Pieces(); PB4.Pieces = 6;
        Pieces PB5 = new Pieces(); PB5.Pieces = 6;
        Pieces PB6 = new Pieces(); PB6.Pieces = 6;
        Pieces PB7 = new Pieces(); PB7.Pieces = 6;
        Pieces PB8 = new Pieces(); PB8.Pieces = 6;
        Pieces PW1 = new Pieces(); PW1.Pieces = 6;
        Pieces PW2 = new Pieces(); PW2.Pieces = 6;
        Pieces PW3 = new Pieces(); PW3.Pieces = 6;
        Pieces PW4 = new Pieces(); PW4.Pieces = 6;
        Pieces PW5 = new Pieces(); PW5.Pieces = 6;
        Pieces PW6 = new Pieces(); PW6.Pieces = 6;
        Pieces PW7 = new Pieces(); PW7.Pieces = 6;
        Pieces PW8 = new Pieces(); PW8.Pieces = 6;
        Pieces KB1 = new Pieces(); KB1.Pieces = 2;
        Pieces KW1 = new Pieces(); KW1.Pieces = 2;
        Pieces QB1 = new Pieces(); QB1.Pieces = 1;
        Pieces QW1 = new Pieces(); QW1.Pieces = 1;
        Pieces BB1 = new Pieces(); BB1.Pieces = 3;
        Pieces BB2 = new Pieces(); BB2.Pieces = 3;
        Pieces BW1 = new Pieces(); BW1.Pieces = 3;
        Pieces BW2 = new Pieces(); BW2.Pieces = 3;
        Pieces NB1 = new Pieces(); NB1.Pieces = 4;
        Pieces NB2 = new Pieces(); NB2.Pieces = 4;
        Pieces NW1 = new Pieces(); NW1.Pieces = 4;
        Pieces NW2 = new Pieces(); NW2.Pieces = 4;
        Pieces RB1 = new Pieces(); RB1.Pieces = 5;
        Pieces RB2 = new Pieces(); RB2.Pieces = 5;
        Pieces RW1 = new Pieces(); RW1.Pieces = 5;
        Pieces RW2 = new Pieces(); RW2.Pieces = 5;
    }
}

public class Pieces{
    int type;     // |1 = Queen|   |2 = King|   |3 = Bishop|   |4 = Knight|   |5 = Rook|   |6 = Pawn|
    int movement; // |1 = Pawn Step|   |2 = Pawn Two Steps|   |3 = Pawn Kill|   |4 = Knight|   |5 = Rook|   |6 = Bishop|   |7 = King|
}

先學OO原理，再學go就好了。 只是想知道你能做什么
