Java Operator Precedence
Java Operator Precedence.When two mathematical operators have the same precedence, they are performed in a left-to-right order.
- Multiplication (*) and division (/) both have equal Operator Precedence but higher than the plus (+) and minus (-).
- Plus (+) and minus (-) both have equal Operator Precedence.
- All with the highest Operator Precedence is performed first and then will operators be performed after a left to right order.
Operator precedence example:
... x = 5 + 3 + 8 * 9 + 6 * 4; // is evaluated multiplication first, left to right. Thus, // 8*9 = 72, and 6*4 = 24. Now the expression is essentially. // x = 5 + 3 + 72 + 24; and result will be x=104; ...
To override this you can use parentheses and/or nesting parentheses:
... TotalPersonSeconds = ( ( (NumMinutesToThink + NumMinutesToType) * 60) * (PeopleInTheOffice + PeopleOnVacation) ); ...
