java初學者如何編寫別踩黑白塊，求編寫內容 在eclipse里，是要有圖形用戶界面的，別亂復制

小弟啊，看來你真的是初學啊，抽象類Friut定義在哪個包中都可以，但是在它的子類中要導入，importFruit這個類，然后在Fruit這個類中定義一個抽象方法harvest（），不做任何實現就可以啦

JAVA中為什么畫出的圖形沒法顯示出來？

你這個是代碼里面拼寫錯誤了，改成下面的可以顯示

class?DontStepOnWhitePiece?extends?JPanel

{

public?void?paint(Graphics?g)???//上面的這里拼寫錯誤，panit

{

super.paint(g);

g.setColor(Color.black);

g.drawRect(0,?0,?100,?100);

}
