Java Language Using Boolean in if statement


Example

Due to auto unboxing, one can use a Boolean in an if statement:

Boolean a = Boolean.TRUE;
if (a) { // a gets converted to boolean
    System.out.println("It works!");
}

That works for while, do while and the condition in the for statements as well.

Note that, if the Boolean is null, a NullPointerException will be thrown in the conversion.
