] | For `long theNumber = inLong;`, the long value of inLong is fetched by implicitly calling `inLong.longValue()`. This is called auto-unboxing (sometimes more general auto-boxing). When inLong is null, you therefore get a NullPointerException just like calling any other method on null.
Therefore, you should think of som... | inLong is probably `null`. Then you try to assign a `null` reference and unbox it into a primitive type. |
7,332,110 | There is a strange thing happening when I execute the following code:
```
private void doStuff(Long inLong) {
long theNumber = inLong;
/* ... */
}
```
Sometimes I see a NullPointerException in the logs at the assignment line and I can't understand why it happens. Any idea? | 2011/09/07 | [

I guess what you want to do is this:
```
theNumber = 0; // or Long.MIN_VALUE or Long.MAX_VALUE or whatever you prefer
if (inLong != null) {
theNumber = inLong;
}
// ...

```
long theNumber = inLong;
```
is semantically equivalent to
```
long theNumber = inLong.longValue();
```
which should make the cause of the NPE obvious. |
