swing图片显示问题

Question

问题遇到的现象和发生背景

swing斗地主，发牌以后，排序重新设置坐标玩，重新绘制图片会堆叠，运行没问题

    }

// System.out.println(mainJPanel.getSendP1List());

}


//排序方法
private void sortCards(List<GamePokerCardType> list) {
    Collections.sort(list, (o1,o2)->{
        //花色值
        int a1 = o1.getColorValue();

        //点数值
        int b1 = o1.getPointValue();
        int b2 = o2.getPointValue();
        int flag = 0;
        //降序排列
        flag = b2 - b1;
        if (flag == 0)
            return a2 - a1;
        else {
            return flag;
        }
    });
}


//打乱牌组 <洗牌> 的方法
private void shufferCard() {
    Collections.shuffle(mainJPanel.getCardList());
}


//重定位
public void rePosition2(List<GamePokerCardType> list,int flag) {
    
    for (int i = 0; i < list.size(); i++) {
        if (flag == 0) {
            list.get(i).setStartX(200);
            list.get(i).setStartY(100+i*15);
        }
        if (flag == 1) {
            list.get(i).setStartX(507+i*21);
            list.get(i).setStartY(800);
        }
        if (flag == 2) {
            list.get(i).setStartX(900);
            list.get(i).setStartY(110+i*15);
        }
    }
}

}
