//class反射编程
//定义一个学生类
public class test124 {public String name;protected int age;double height;private double money;public void setName(String name) {this.name = name;}public String getName() {return name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public test124(String name, Integer age){this.name=name;this.age=age;System.out.println( "调用有参构造方法" );}public test124(String name,int age,double money){this.name=name;this.age=age;this.money=money;}//看书public void learn(BookRead book){System.out.println( "我的名字"+name+ "我正在学习"+book.getName());}//奔跑public void run(){System.out.println( "我们喜欢奔跑" );}
}

定义一个method类

import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.lang.reflect.Modifier;//method类反射机制
public class test129 {public static void main(String[] args){try {Class<?> stuCla = Class.forName( "test124" );test124 stuObj=new test124( "geyao",12 );BookRead book=new BookRead();book.setName( "歌谣" );Method learnMet=stuCla.getMethod( "learn", BookRead.class);learnMet.invoke( stuObj,book );//获取非公共方法Method runMet=stuCla.getDeclaredMethod( "run");if(!runMet.isAccessible()){runMet.setAccessible( true );runMet.invoke( stuObj );}}catch (Exception e){e.printStackTrace();}}
}

定义一个bookread类

public class BookRead {private String name;public void setName(String name) {this.name = name;}public String getName() {return name;}
}
