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
**

- Subtraction operator

* Multiplication operator

/ Division operator

% Remainder operator

+ 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

== Equal to

!= Not equal to

> Greater than

>= Greater than or equal to

< Less than

<= Less than or equal to

&& Conditional-AND

|| Conditional-OR

?: Ternary (shorthand for if-then-else statement)

instanceof Compares an object to a specified type

~ 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.

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 exponential operator

Thanks for the rich information you have gathered here. i will like to know the operator used for exponential operation.e.g. solving 2 to the power 3 equals 8.
