想了解java反射使用示例讲解的相关内容吗，在本文为您仔细讲解java反射的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：反射，下面大家一起来学习吧。
public class ReflexTest {
public static void main(String[] args)
throws ClassNotFoundException, NoSuchMethodException, SecurityException,
IllegalAccessException, IllegalArgumentException, InvocationTargetException,
InstantiationException {
//参数类型
Class[] paramTypes = new Class[3];
paramTypes[0] = String.class;
paramTypes[1] = Integer.class;
paramTypes[2] = String.class;
//取得方法
Method m = Demo.class.getDeclaredMethod("getSome", paramTypes);
//参数设置
Object[] os = new Object[3];
os[0] = "pp";
os[1] = 4;
os[2] = "3";
//方法调用
m.invoke(Demo.class.newInstance(), os);
}
}
class Demo{
public void getSome(String name,Integer year, String age){
System.out.println("name is :" + name + ";age is :" + age + ";i is :" + year);
}
}
