import java.lang.reflect.Constructor;

Person p = new Person();
//获取Class对象的三种方式
Class clazz1 = Person.class;

Class clazz3 = Class.forName("Person");
System.out.println("clazz1="+clazz1.toString());
System.out.println("clazz2="+clazz2);

//获取所有构造方法的两种方式
Constructor con1 = clazz1.getConstructor();
System.out.println("con1 = "+con1);
Constructor con2 = clazz1.getConstructor(String.class,int.class);
System.out.println("con2 = "+con2);
