可以有多种方式判断类的名字：
假定所有的类都以com，org，或者net开头
搜索classpath来寻找名字为Hack的类
搜索classpath来寻找映射到这个文件的目录入口
直接查看类自身。对于所有的情况下，这是最直接的
Java规范规定了如何查看一个class文件。存储在class文件一开始的一个值就是以Java内部分割符“/”为格式的完整的类明。
下面的代码返回了文件C:\code\hacks\research\com\generationjava\Hack.class的内部类名com/generationjava/Hack，读者可以进一步编写代码将“/”转换成“.”：
static final public int MAGIC = 0xCAFEBABE;
// 传递C:\code\hacks\research\com\generationjava\Hack.class
// 假定存在这样一个类
public String getFullyQualifiedName(String filename) throws IOException {
String name = null;
try {
DataInputStream in = new
DataInputStream(new FileInputStream(filename));
if(in.readInt() != MAGIC) {
// 不是一个.class文件
thrownew IOException("Not a class file");
}
in.readUnsignedShort();// 次版本号
in.readUnsignedShort();// 主版本号
in.readUnsignedShort();// 长度
in.readByte();// CLASS=7
in.readUnsignedShort();// 忽略这个地方
in.readByte();// UTF8=1
name =in.readUTF();//类的名字!!!
in.close();
} catch(IOException ioe) {
ioe.printStackTrace();
}
return name;
}
当你直接从.class文件中获得类的信息的时候，就简化了开发。查找一个匿名.class类文件的完整的类名是任何基于.class文件工作的应用的重要部件。
