The Java programming language supports various arithmetic operators for all floating point

and integer numbers. These operators are (+)(addition), (-)(subtraction),(*)

(multiplication), (/)(division), and (%)(modulo). The following table summarizes the

binary arithmetic operations in the Java programming language.

Operator Use Description

Operator | Use | Description |
---|---|---|

+ | op1 + op2 | Adds op1 and op2; also used to concatenate strings |

– | op1 – op2 | Subtracts op2 from op1 |

* | op1 * op2 | Multiplies op1 by op2 |

/ | op1 / op2 | Divides op1 by op2 |

% | op1 % op2 | Computes the remainder of dividing op1 by op2 |

So Let’s take an example to understand operators better
