9.5    Parentheses

With parentheses, you can influence the order of calculations within an expression, just like in mathematics. This achieves roughly the same effect as if you were to split the expression into multiple statements. Therefore,

int interest = 3 * (4 + 7) * 8;  

is the same as

int intermediateResult = 4 + 7;int interest = 3 * intermediateResult * 8;.  

The order of other evaluations (here, *) is not affected.
