使用java反射中的getMethod,invoke方法調用對象方法的執行個體

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);}}
