@mind3x #14 你说“A reference to a static field (§8.3.1.1) causes initialization of only the class or interface that actually declares it”来源于官方文档，一定是正确的。难道“a field that is both static and final, and initialized by a compile-time constant expression”不是一个“static field”？

比如我将 NewbornBaby 改为下面这样：

```
class NewbornBaby extends NewParent {

static int hoursOfCrying = 6 + (int) (Math.random() * 2.0);

static final int hoursOfSleep = 6; // a field that is both static and final, and initialized by a compile-time constant expression

static {
System.out.println("NewbornBaby was initialized.");
}
}
```

运行 java -verbose Example2，可以看出 NewbornBaby 被没有被 loaded 。
