Java Compile Error: Unexpected Type required: variable found: value

Question

I'm getting this Java Compile Error: "Unexpected Type required: variable found: value". I realize in general, this means I'm probably doing something like 1.0 = mydouble; That's backwards. But, I'm not seeing my error in this code: ``` private Double bid; public void setBid(double bid) { Double.isNaN(bid) ? this.bid = 0.0 : this.bid = bid; } ```

Accepted Answer

A ternary operator can only operate conditionally on values, not entire statements. Therefore, you would need to rewrite your code as:

```
this.bid = Double.isNaN(bid) ?  0.0 : bid;
```

Also, do you have a specific need to declare the field `bid` as a `java.lang.Double` (reference type) and not the primitive `double`?
