//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 test124(String name,Integer age){
this.name=name;
this.age=age;
}
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bookread类public class BookRead {
private String name;
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
定义测试类public class test125 {
/*使用class实现反射编程，创建对象，获取类的相关信息
* */
public static void main(String[] args){
String packageName=test124.class.getPackage().getName();
System.out.println( "包名"+packageName);
try {
Class<?> stuClass=Class.forName( "test124" );
System.out.println( stuClass.getName() );
//使用字节码对象获取这个对象的实例
test124 stuObj=(test124)stuClass.newInstance();
System.out.println(stuObj!=null );
}catch (Exception e){
}
}
}
运行结果
