java中的反射机制对属性和方法的操作

Class c = Class.forName("com.test1.Student");
Student st = new Student();
Field f = c.getField("name");
System.out.println("请输入学生姓名");
f.set(st, input.next());
Field f1 = c.getField("age");
System.out.println("请输入学生年龄");
f1.set(st, input.nextInt());
Field f2 = c.getField("sex");
System.out.println("请输入学生性别");
f2.set(st, input.next());
Field f3 = c.getDeclaredField("stno");
System.out.println("请输入学生编号");//属性为私有的
f3.setAccessible(true);
f3.set(st, input.next());
Method m = c.getMethod("show");
m.invoke(st);
