In Java there is an order to how operators are evaluated.
* (multiplication), / (division) and % (modulo) are evaluated first.
+ (addition) and – (subtraction) are evaluated next.
= (assignment) is evaluated last.
When there are multiple operators that would evaluated at the same time, they are picked in order from left to right.
answer = ab%c – d/e+f would be resolved in this order:
First, a * b would be evaluated.
Second, % c would be evaluated.
Third, d / c would be calculated.
Fourth, the + would be evaluated.
Fifth, the – would be evaluated…
Finally the assignment (setting the variable answer to the calculated value) would be evaluated.
