Java-“返回对象”和“返回（对象）”之间的区别

Question

Is there any special difference between (maybe compiler level?)

public byte[] getSalt() {
    return salt;
}

and

public byte[] getSalt() {
    return (salt);
}

Answer 1

No, unless you are typecasting..

public byte[] getSalt() {
    return (byte[])salt;
}

Answer 2

Writing return x indicates a programmer who understands what return means. Whereas return(x) indicates a programmer who incorrectly believes that return is a kind of function.
