java初学者如何编写别踩黑白块，求编写内容 在eclipse里，是要有图形用户界面的，别乱复制
小弟啊，看来你真的是初学啊，抽象类Friut定义在哪个包中都可以，但是在它的子类中要导入，importFruit这个类，然后在Fruit这个类中定义一个抽象方法harvest（），不做任何实现就可以啦
JAVA中为什么画出的图形没法显示出来？
你这个是代码里面拼写错误了，改成下面的可以显示
class DontStepOnWhitePiece extends JPanel
{
public void paint(Graphics g) //上面的这里拼写错误，panit
{
super.paint(g);
g.setColor(Color.black);
g.drawRect(0, 0, 100, 100);
}
JAVA别踩白块怎么让一行除了黑块其他都是白块
