Proxy基础---------获取collection接口的构造跟方法

1----查看proxy api

2------测试代码

 package cn.proxy01;
 import java.lang.reflect.Constructor;
 import java.lang.reflect.Method;
 import java.util.Collection;
 public class Proxy {
     public static void main(String[] args) {
         Class clazzProxy = java.lang.reflect.Proxy.getProxyClass(Proxy.class.getClassLoader(), Collection.class);
         System.err.println("代理名称："+clazzProxy.getName());
         System.err.println("--------通过代理获取collection的构造 ---------------");
         //$Proxy0()
         //$Proxy(参数名,参数类型)
         Constructor[] constructors = clazzProxy.getConstructors();
         for(Constructor constructor : constructors){
             String constructionName = constructor.getName();
             StringBuilder builder = new StringBuilder(constructionName);
             builder.append("(");
             Class[] parameters = constructor.getParameterTypes();
             for(Class params : parameters){
                 String param = params.getName();
                 builder.append(param+",");
             }
             if(parameters.length != 0 || parameters != null){
                 builder.deleteCharAt(builder.length()-1);
             }
             builder.append(")");
             System.err.println(builder.toString());
         }
         System.err.println("--------通过代理获取collection的方法 ---------------");
         //remove(java.lang.Object)
         Method[] methods = clazzProxy.getMethods();
         for(Method method : methods){
             String methodName = method.getName();
             StringBuilder builder = new StringBuilder(methodName);
             builder.append("(");
             Class[] parameters = method.getParameterTypes();
             for(Class params : parameters){
                 String param = params.getName();
                 builder.append(param+",");
             }
             if(parameters.length != 0 || parameters != null){
                 builder.deleteCharAt(builder.length()-1);
             }
             builder.append(")");
             System.err.println(builder.toString());
         }
     }
 }
