Is there a difference between return (val) and return val ?

    There is no difference. Something is indicated in brackets usually to improve readability (in expressions, the priority of operations can be placed this way).

    Brackets work the same way: for example, such expressions will be completely similar in terms of work, but the first one is better read:

     (variable == null) ? this.pullVariable(variable) : this.pushVariable(variable); variable == null ? this.pullVariable(variable) : this.pushVariable(variable);

    Also in Java, type brackets are used for conversion. For example:

     Object object = (Object) variable;

    The same transformation can be used with the return :

     return (Object) variable;

    • It can be read better in the first case, everywhere its rules. But the first case seems to hint at the lack of knowledge of the priorities of the operation as a consequence of excessive brackets. I apologize for such a comment, but could not not write.
