    Opposite of the Pull Up Field refactoring is push down field. Again, this is a pretty straight forward 
    refactoring without much description needed 
     1: public abstract class Task 
     2: { 
     3: protected string _resolution; 
     4: } 
     5: 
     6: public class BugTask : Task 
     7: { 
     8: } 
     9: 
     10: public class FeatureTask : Task 
     11: { 
     12: } 
     
    In this example, we have a string field that is only used by one derived class, and thus can be pushed down 
    as no other classes are using it. It’s important to do this refactoring at the moment the base field is no 
    longer used by other derived classes. The longer it sits the more prone it is for someone to simply not touch 
    the field and leave it be. 
     1: public abstract class Task 
     2: { 
     3: } 
     4: 
     5: public class BugTask : Task 
     6: { 
     7: private string _resolution; 
     8: } 
     9: 
     10: public class FeatureTask : Task 
     11: { 
     12: }

    Today we look at a refactoring that is similar to the Pull Up method. Instead of a method, it is obviously 
    done with a field instead! 
     1: public abstract class Account 
     2: { 
     3: } 
     4: 
     5: public class CheckingAccount : Account 
     6: { 
     7: private decimal _minimumCheckingBalance = 5m; 
     8: } 
     9: 
     10: public class SavingsAccount : Account 
     11: { 
     12: private decimal _minimumSavingsBalance = 5m; 
     13: } 
     
    In this example, we have a constant value that is duplicated between two derived classes. To promote 
    reuse we can pull up the field into the base class and rename it for brevity. 
     1: public abstract class Account 
     2: { 
     3: protected decimal _minimumBalance = 5m; 
     4: } 
     5: 
     6: public class CheckingAccount : Account 
     7: {

  • Field field =cls.getDeclaredField("gender");   获取属性的名字 System.out.println(field.getName());   获取属性的类型 Class strcls =field.getType(); System.out.println...
    Class
    由于Class类没有公共构造方法,所有创建Class的对象的方法有以下几种:
     
    1).通过Class.forName()静态方法返回Class类的一个实例
    Class cls=Class.forName("model.Dog"); Class cls1=Class.forName("model.Person");

     

    2).通过类名.class来获取一个class类的实例
    cls =Dog.class;

     

    3).代码运行在非静态区通过this.getClass()获取Class
    Class cls= this.getClass();

     

     
    Class对象既然是描述一个类,那么我们通过该Class的实例能够做什么事情呢?
    类的属性
    获取类名
    System.out.println(cls.getName()); System.out.println(cls.getSimpleName());

     

    获取类的修饰限定符
    int modi = cls.getModifiers(); System.out.println(modi);

     

     
    --获取一个类的属性
    1.根据一个属性名获取一个public属性的描述
    Field field = cls.getField("name");

     

    2.获取一个类的全部public属性的描述
    Field[] fields = cls.getFields(); System.out.println(fields.length);

     

     
    3.根据一个属性名获取一个在类中声明的属性的描述
    Field declaredField = cls.getDeclaredField("gender");

     

    4.获取所有在类中声明的属性的描述
    Field[] declaredFields = cls.getDeclaredFields(); System.out.println(declaredField);

     

     
    --获取一个类的方法,通过四个方法获取method对象
    1.根据一个方法的名字获取类中的一个public的方法的描述
    Method method = cls.getMethod("run", String.class,int.class);

     

    2.获取所有在类中是public的方法的描述
    Method[] methods = cls.getMethods();

     

     
    3.根据一个方法名获取在类中声明的一个方法的描述
    Method declaredMethod = cls.getDeclaredMethod("eat", null);

     

    4.获取所有在类中声明的方法的描述
    Method[] declaredMethods = cls.getDeclaredMethods();

     

     
     
    返回cls所代表的类的实例
    Object obj = cls.newInstance(); System.out.println(obj);

     

     
    可以传参
    Constructor c = cls.getConstructor(String.class); c.newInstance("aaa");

     

     
     
     
    field
     
    获取所有属性
    Field[] declaredField =cls.getDeclaredFields(); for (Field filed:declaredField) { System.out.println(filed.getName()); }

     

    使用Filed类的一个实例,来描述cls类的实例中的"一个"属性
    Field field =cls.getDeclaredField("gender");

     

    获取属性的名字
    System.out.println(field.getName());

     

    获取属性的类型
    Class strcls =field.getType(); System.out.println(strcls.getName());

     

    获取属性的限定符
    int modifiers =field.getModifiers(); System.out.println(modifiers);

     

     
    创建Dog类的一个对象
    Dog d = new Dog("旺财","母"); System.out.println(d.getGender());

     

    暴力设置:设置field的访问
    field.setAccessible(true);

     

     
    有d对象,希望给d对象的gender属性赋值,可以使用set方法
    field.set(d, "公"); System.out.println(d.name); System.out.println(field.get(d));

     

     
     
    method
    通过cls.getDeclaredMethod获取Method对象
    Method m=cls.getDeclaredMethod("run",String.class,int .class); Method m=cls.getDeclaredMethod("eat",null);

     

     
     
    获取方法名
    System.out.println(m.getName());

     

     
    方法的返回值类型
    Class returntype = m.getReturnType(); System.out.println(returntype.getName());

     

     
    方法的参数类型
    Class[] paraType = m.getParameterTypes(); for (int i = 0; i < paraType.length; i++) { System.out.println(paraType[i].getName()); }

     

    获取方法的修饰符
    int modifiers = m.getModifiers(); System.out.println(modifiers); Dog d = new Dog("旺财", "母");

     

     
     
    方法是可以执行的,使用invoke执行method对象所表示的方法
    m.invoke(d, "aaa",123);

     

    m为静态
    m.invoke(null,null);

     

     
     
     
     
    /使用反射相关类,为对象p设置name属性的值
    Person p=new Person();
     //使用反射相关类,为对象p设置name属性的值 
    Class cls=p.getClass(); 
    Field[] fs=cls.getDeclaredFields(); 
    for (int i = 0; i < fs.length; i++) { 
    Field f = fs[i]; 
    if(f.getName().equals("name")) {
     String setName = "set"+f.getName().substring(0, 1).toUpperCase()+ f.getName().substring(1);
     //设置器的形参和属性的类型应当一致
     Method m = cls.getDeclaredMethod(setName, f.getType());
     //相当于p方法调用了setName方法
     m.invoke(p, "张山"); 
    }
     } 
    System.out.println(p.getName());
