Operators
Operators are symbols that performs some operations on
one or more than one operands. Once we declare and initialize variables, we can
use operators to perform certain tasks like addition, subtraction etc.
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
&& ConditionalAND
 ConditionalOR
?: Ternary (shorthand for ifthenelse statement)
Type Comparison Operator
instanceof Compares an object to a specified type
Bitwise and Bit Shift Operators
~ Unary bitwise complement
<< Signed left shift
>> Signed right sift
>>> Unsigned right shift
& Bitwise AND
^ Bitwise exclusive OR
 Bitwise inclusive OR
These operators follow some precedence to apply. The
table below shows the list of operators that follow the precedence. Operators with higher precedence are evaluated before operators with relatively lower precedence.
However, Operators on the same line have equal precedence. The rule to deal with
equal precedence operators is that all binary operators except for the assignment operators are evaluated from left to right; assignment operators are evaluated right to left.
