Exams like SCJP test your understanding of Java operators and how to use them like:
assignment operators: =, +=, -=
arithmetic operators: +, -, *, /, %, ++, --
relational operators: < , , >=, ==, !=
logical operators: &, |, ^, !, &&, ||
conditional operators: ? :
Also operators to check the equality of two objects or two primitives
In the following table operators and their precedences are shown. Upper rows operators have higher precedence. Same row operators have equal precedence. For equal precedence operators, All binary operators except the assignment operators work from left to right while assignment operators work from right to left.
| 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 | = += -= *= /= %= &= ^= |= < >= >>>= |
The following quick reference summarizes the operators supported by the Java programming language.
Simple Assignment Operator
= Simple assignment operator
Arithmetic Operators
+ Additive operator (also used for String concatenation)- Subtraction operator* Multiplication operator/ Division operator% Remainder operator
Unary Operators
+ Unary plus operator; indicates positive value (numbers are positive without this, however)- Unary minus operator; negates an expression++ Increment operator; increments a value by 1-- Decrement operator; decrements a value by 1! Logical compliment operator; inverts the value of a boolean
Equality and Relational Operators
== Equal to!= Not equal to> Greater than>= Greater than or equal to< Less than<= Less than or equal to
Conditional Operators
&& Conditional-AND|| Conditional-OR?: Ternary (shorthand forif-then-elsestatement)
Type Comparison Operator
instanceof Compares an object to a specified type
Bitwise and Bit Shift Operators
~ Unary bitwise complement< > Signed right shift>>> Unsigned right shift& Bitwise AND^ Bitwise exclusive OR| Bitwise inclusive OR
