What are order of precedence and associativity how are they used ?
Answer : Please have below operators and list are in according to its precedence order and some points:
- Table top starts from highest precedence.
- Those operators who has higher precedence will be evaluated before compare to operators with lower precedence
- When operators are on same line they will have equal precedence
- If operators of equal precedence appears in same expression then a rule will govern which will be evaluated first
- All binary operators except for the assignment operators will be evaluated from left to right
- Assignment operators will be evaluated from right to left
Operator Precedence
| Operators | Precedence |
| postfix | expr++ expr– |
| unary | ++expr –expr +expr -expr ~ ! |
| multiplicative | * / % |
| additive | + – |
| shift | << >> >>> |
| relational | < > <= >= instanceof |
| equality | == != |
| bitwise AND | & |
| bitwise exclusive OR | ^ |
| bitwise inclusive OR | | |
| logical AND | && |
| logical OR | || |
| ternary | ? : |
| assignment | = += -= *= /= %= &= ^= |= <<= >>= >>>= |
