Treflection05_扩展习题

1、

package reflectionZ;

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;

public class Treflection05
{
    // 第17讲 【20:40】之后
    
    public static void main(String[] args) throws Exception
    {
        Tinfo info = new Tinfo();
        Class<?> clazz = Class.forName(info.FclassPath);
        Object obj = clazz.newInstance();
        
        Class<?> clazzParameter = Class.forName(info.FparameterType);
        Constructor<?> constructor = clazzParameter.getConstructor(String.class);
        Object objParameter = constructor.newInstance(info.FparameterVal);
        
        Method method = clazz.getMethod(info.Fmethod, clazzParameter);
        method.invoke(obj, objParameter);
    }
}

class Dog
{
    public void Cry(String name)
    {
        System.out.println("Cry : "+name);
    }
}

class Tinfo
{
    public String FclassPath = "reflectionZ.Dog";
    public String Fmethod = "Cry";
    public String Fparameter = "name";
    public String FparameterType = "java.lang.String";
    public String FparameterVal = "小狗狗";
}
