Check if null Boolean is true results in exception
java
Solution
When you have a `boolean` it can be either `true` or `false`. Yet when you have a `Boolean` it can be either `Boolean.TRUE`, `Boolean.FALSE` or `null` as any other object.
In your particular case, your `Boolean` is `null` and the `if` statement triggers an implicit conversion to `boolean` that produces the `NullPointerException`. You may need instead:
if(bool != null && bool) { ... }
Problem
I have the following code: ``` Boolean bool = null; try { if (bool) { //DoSomething } } catch (Exception e) { System.out.println(e.getMessage()); } ``` Why does my check up on the Boolean variable "bool" result in an exception? Shouldn't it just jump right past the if statement when it "sees" that it isn't true? When I remove the if statement or check up on if it's NOT null, the exception goes away.
