java一个最简单的反射的例子

最基本的反射 通过一个类的根目录 String生成（newInstance）一个对象

接口

package org.fashe.test;

public interface FansheInterface {
    public void shuchu();
}

实现

package org.fashe.test;

public class FansheImpl implements FansheInterface {

    public void shuchu() {
        System.out.println("反射成功！！");

    }

}

main方法测试

package org.fashe.test;

public class Testfashe {
    public static void main(String[] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
     Class forName = Class.forName("org.fashe.test.FansheImpl");
     FansheInterface fasheobj  = (FansheInterface) forName.newInstance();
     fasheobj.shuchu();
    }

}
