List the Parentheses used in Java language?

As usual here's the output:
% javac FahrToCelsius.java
% java FahrToCelsius
0 -17.7778
20 -6.66667
40 4.44444
60 15.5556
80 26.6667
100 37.7778
120 48.8889
140 60
160 71.1111
180 82.2222
200 93.3333
220 104.444

260 126.667
280 137.778
300 148.889

This program is a little more included than the previous examples. Mostly it's stuff you've seen before by so a line through line analysis isn't essential. The line to be concerned along with is

celsius = (5.0 / 9.0) * (fahr-32.0);

This is a virtual translation of the formula C = (5/9)(F - 32) with the single change in which a * was added since Java does not implicitly multiply items in parentheses. The parentheses are used only as they are in regular algebra, to adjust the precedence of terms in a formula. Actually the precedence of operations in which use the primary arithmetic operators (+, -, *, /) is accurately the similar as you learned in high school algebra.

Notice, you can always use parentheses to modify the order of evaluation. Everything inside the parentheses will be computed before anything outside of the parentheses is computed. If you're in doubt it never hurts to put in extra parentheses to clear up the order in that terms will be evaluated.
