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());
        }
    }
}
