英文:
Java exception stacktrace has "$8", what does this mean?
问题
这不是我第一次看到异常消息，但我对堆栈跟踪中的特殊字符含义很好奇。我在Android中使用Java，此异常在类名旁边显示了一个$8，然后显示了发生异常的方法名。
我进行了研究，但未能找到有关其含义的任何信息。以下是堆栈跟踪和我所指的$8。
java.lang.Exception: 错误，服务器响应 400
at cb.cheneytracker.service.callers.ServerCaller$8.onResponse(ServerCaller.java:858)
at retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall$1$1.run(DefaultCallAdapterFactory.java:83)
更准确地说，由于我因为“需要详细信息或清晰度”而受到了投票下降。在上面的异常堆栈跟踪中，$代表什么？我看到了$8和$1$1，这些是什么意思？
英文:
So this is not the first time I see exception messages but I'm curious as to what the special characters mean in the stacktrace. I'm using Java in Android and this exception shows a $8 right next to the class name then the method name where the exception took place.
I was researching but was not able to find any information on what it means. Below is the stacktrace and the $8 I'm referring to.
java.lang.Exception: Error, server response 400
at cb.cheneytracker.service.callers.ServerCaller$8.onResponse(ServerCaller.java:858)
at retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall$1$1.run(DefaultCallAdapterFactory.java:83)
So to be more precise, since i'm getting down-voted for "needs detail or clarity". What does $ mean in the exception stack trace above. I see $8 and $1$1, what do these mean?

以下是翻译好的部分：
这是匿名类的自动生成名称，它是“8”，因为容器类中至少有8个匿名类，您可以在以下示例中看到其效果：
interface Test {
void doSomething();
}
public static Test createTest() {
return new Test() {
@Override
public void doSomething() {
System.out.println("我在忙...");
}
};
}
public static Test createAnotherTest() {
return new Test() {
@Override
public void doSomething() {
System.out.println("好的");
}
};
}
public static void main(String[] args) {
Test t = createTest();
System.out.println(t.getClass().getName());
t = createAnotherTest();
System.out.println(t.getClass().getName());
}
英文:
It is the auto generated name for anonymous class, it is 8 because there are at least 8 anonymous class in the container class, you can see it in action here:
interface Test {
void doSomething();
}
public static Test createTest() {
return new Test() {
@Override
public void doSomething() {
System.out.println("I'm busy...");
}
};
}
public static Test createAnotherTest() {
return new Test() {
@Override
public void doSomething() {
System.out.println("Ok");
}
};
}
public static void main(String[] args) {
Test t = createTest();
System.out.println(t.getClass().getName());
t = createAnotherTest();
System.out.println(t.getClass().getName());
}

我知道，这是编译器自动生成的匿名类的名称。
英文:
As I know, it is a name of anonymous class that compiler automatically generated
