1，定义一个水果类(fruit),水果类中的有
【属性】：颜色(color)、价格(price)、重量(weigth),
再定义一个<测试类>,
创建一个苹果(apple)的对象, 颜色是"红色",价格是5.5,重量10g。
然后再创建一个香蕉(banana)的对象,颜色是"黄色",价格是4.2,重量5g。
最后输出：
苹果的颜色、价格、重量、
香蕉的颜色、价格、重量、

4,写一个传奇游戏中的猪类，类中有属性：颜色(color)、重量(weight)、攻击力(attack)、准确度(accuracy)。再写一个测试类，生成一个猪的对象，将此猪的颜色值为“白色(white)”，重量为5，攻击力为50点，准确度为0.8。要求输出此猪的信息格式为：一只白色的猪，重量5，攻击为50点血，准确度为0.8，我好怕怕呀!

55         Pig pig=new Pig("白色",5,50,0.8);
56         
57         System.out.println("一只"+pig.getColor()+"的猪，重量"+pig.getWeight()+"，"
58         + "为"+pig.getAttack()+"点血，准确度为"+pig.getAccuracy()+"，我好怕怕呀!");
