注解和反射11.获取类运行时的结构

public class Test {
public static void main(String[] args) throws ClassNotFoundException, NoSuchFieldException, NoSuchMethodException {
Class c1 = Class.forName(“lesson02.Test”);
System.out.println(c1.getName());//获得包名+类名

    System.out.println(c1.getSimpleName());//获得类名
    //获得类的属性
    System.out.println("--------------------------");
    Field[] fields = c1.getFields(); //只能找到public属性
    fields = c1.getDeclaredFields();
    for (Field field:fields//找到全部的属性
         ) {
        System.out.println(field);
    }
    Field name = c1.getDeclaredField("name");//指定属性
    System.out.println(name);
    System.out.println("========================");
    Method[] methods = c1.getMethods();//获得本类及其父类的所有方法
    for (Method method : methods) {
        System.out.println("正常的"+method);
    }
    methods=c1.getDeclaredMethods();
    for (Method method : methods) {
        System.out.println("getDeclaredMethods"+method);
    }
    //获得指定方法
    //重载
    Method getName =   c1.getMethod("getName",null);
    Method setName =c1.getMethod("setName",String.class);
    //
}
