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
