Java Class.forName()无法加载类

package chapter14.typeinfo;
class Candy{static{System.out.println("loading Candy");}}
class Gum{static{System.out.println("loading Gum");}}
class Cookie{static{System.out.println("loading Cookie");}}

public class SweetShop {
public static void main(String[] args){
System.out.println("inside main");
new Candy();
System.out.println("after creading candy");
try {
Class.forName("Gum");
} catch (ClassNotFoundException e) {
System.out.println("couldn't find Gum");
}
System.out.println("After Class.forName(\"Gum\")");
new Cookie();
System.out.println("After creating cookie");
}
}

/*inside main
loading Candy
after creading candy
couldn't find Gum
After Class.forName("Gum")
loading Cookie
After creating cookie*/


从输出结果来看，代码Class.forName("Gum")； 中Gum类没有被JVM加载到。    望指教，为什么这个类加载不了呢？ 万分感谢。。。。

很明显
要
chapter14.typeinfo.Gum

是的，后来发现是没写全包名。。。       谢谢！
