实验3类和对象

声明Patient类表示在门诊室中的病人。

（1）此类对象应该包括name(String)、sex(char)、age(int)、weight(float)、allergies(boolean)。

（2）这些属性只能被该类访问。

（3）在该类中声明存取及修改方法。

 (4)该类中至少提供一个构造函数，例如：public Patient(String name),其中构造函数的参数是name。

（5）在一个单独的TestPatient类中，声明测试方法，并生成两个patient对象，设置其状态并将信息显示在屏幕上。

（6）声明并测试toString（）方法，在该方法中显示该病人的全部属性信息。

下面是测试一个patient的例子。

                Patient p1=new Patient(“zhangsan”);

p1.setSex(‘f’);

p1.setAge(18);

p1.setWeight(100.00f);

p1.setAllergies(false);

System.out.println(“name=” + p1.getName());

System.out.println(“sex=” + p1.getSex());

System.out.println(“age=” + p1.getAge());

System.out.println(“weight=” + p1.getWeight());

System.out.println(“allergies=” + p1.getAllergies());

System.out.println(p1.toString());
