使用java反射中的getMethod,invoke方法调用对象方法的实例

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public class AsClass {
public X x;

@SuppressWarnings({ "rawtypes", "unchecked" })
public static void main(String[] args) throws InstantiationException,
ClassNotFoundException, SecurityException, NoSuchMethodException,
IllegalArgumentException, IllegalAccessException,
InvocationTargetException {
AsClass ac = new AsClass();
ac.x = new X();
String acName = ac.x.getClass().getSimpleName();

Class fake_x = Class.forName(acName);
Class[] newClass = new Class[1];
newClass[0] = String.class;

Method x_fun = fake_x.getMethod("show", newClass);
Object[] obj = new Object[1];
obj[0] = "Hello World";

x_fun.invoke(fake_x.newInstance(), obj);

}
}

class X {
public void show(String str) {
System.out.println(str);
}
}
