Arithmetic operators are used to perform arithmetic operations on variables and data.

Operator | Name | Description | Example |
---|---|---|---|

+ | Addition | It adds to values | x+y |

* | Multiplication | It multiplies to values | x*y |

- | Subtraction | It subtracts one value from other | x-y |

/ | Division | Divides on value by another one | x+y |

% | Modulus | Return the Divion Reminder | x%y |

### + Operator example

## (2)Logical Operators in Java Operators

Logical operators are used to determine the logic between variables or values:

Operator | Name | Description | Example |
---|---|---|---|

&& | Logical and | Returns true if both statements are true | y > 3 && y< 100 |

|| | Logical or | Returns true if one of the statements is true | x > 15 || x < 10 |

! | Logical not | Reverse the result, returns false if the result is true | !(x > 5 && x < 20) |

## && Operator

### Explanation:

Code | Explanation |
---|---|

int x =10; | Declare variable name x with data type int and store 10 inside it. Declare variable name y with data type int and store 5 inside it. |

if(x>5 && x<15){ | Checking and condition, if x is greater than 5 and less than 15 which is true as x contain 10 which is greater then 5 and less then 15, so here && condition is true. |

System.out.println("True"); | As && condition is true so here True will be printed on the Screen. |

System.out.println("False"); | If && condition is false then False will be printed on the Screen. |

## || Operator

Code | Explanation |
---|---|

int x =10; | Declare variable name x with data type int and store 10 inside it. Declare variable name y with data type int and store 5 inside it. |

if(x>40 || x<5) | Checking logically or condition, if x is greater than 40 or x is less than 5 which is false as x contain 10 which is less than 40 and greater than 5, so here || condition is false. |

System.out.println("False"); | As || condition is false so here False will be printed on the Screen. |

System.out.println("True"); | If || condition is true then True will be printed on the Screen. |

## ! Operator

### Explanation:

Code | Explanation |
---|---|

int x =50; | Declare variable name x with data type int and store 50 inside it.Declare variable name y with data type int and store 5 inside it. |

if(!(x>40)) | Checking logically not condition, if x is greater than 40 is true because x contain 50 now as we using logical not ! operator so it’s return false |

System.out.println("False"); | As ! condition return false because x>40 return true, so False will be printed on the screen. |

System.out.println("True"); | If x>40 return false than ! operator returns true and True will be printed on the screen. |

## (3)Assignment Operators in Java Operators

Assignment operators are used to assign values to variables.

Operator | Example | Equal To |
---|---|---|

= | x=10 | x=10 |

+= | x+=4 | x=x+4 |

*= | x *=4 | x=x*4 |

-= | x-=6 | x=x-6 |

/= | x /=2 | x = x/2 |

%= | x%2 | x=x%2 |

## = Operator

### Explanation:

Code | Description |
---|---|

int x =50; | = Operate assign the value to x which is 50 |

System.out.println(x); | System.out.println() is the function which take argument name x which contain value 50 and print on the console. |

## += Operator

### Explanation:

Code | Description |
---|---|

int x =50; | = Operate assign the value to x which is 50 |

x+=4 | x+=4 is equal to x=x+4 so as x=50 and x=50+4, so now x contains 54. |

System.out.println(x); | System.out.println() is the function which take argument name x which contain value 54 and print on the console. |

## *= Operator

### Explanation:

Code | Description |
---|---|

int x =50; | = Operate assign the value to x which is 50 |

x*=4 | x*=4 is equal to x=x*4 so as x=50 and x=50*4, so now x contains 200. |

System.out.println(x); | System.out.println() is the function which take argument name x which contain value 200 and print on the console. |

## -= Operator

### Explanation:

Code | Description |
---|---|

int x =50; | = Operate assign the value to x which is 50 |

x-=4 | x-=4 is equal to x=x-4 so as x=50 and x=50-4, so now x contains 46. |

System.out.println(x); | System.out.println() is the function which take argument name x which contain value 46 and print on the console. |

## /= Operator

### Explanation:

Code | Description |
---|---|

int x =50; | = Operate assign the value to x which is 50 |

x/=2 | x/=2 is equal to x=x/2 so as x=50 and x=50/2, so now x contains 25. |

System.out.println(x); | System.out.println() is the function which take argument name x which contain value 25 and print on the console. |

## %= Operator

### Explanation:

Code | Description |
---|---|

int x =23; | = Operate assign the value to x which is 23 |

x%=2 | x%=2 is equal to x=x%2 so as x=23 and x=23%2, so x contains 1 as the remainder is 1. |

System.out.println(x); | System.out.println() is the function which take argument name x which contain value 1 and print on the console. |

## (4)Comparison Operators in Java Operators

Comparison operators are used to compare two values stored inside variables.

Following comparison operators are used in java language.

Operator | Name | Description | Example |
---|---|---|---|

== | Equal to | Checking value stored inside x variable is equal to value stored inside variable y. | x == y |

!= | Not equal to | Checking value stored inside x is not equal to value stored inside variable y. | x != y |

> | Greater than | Checking value stored inside x is greater than value stored inside variable y. | x > y |

< | Less than | Checking value stored inside x is less then value stored inside variable y. | x < y |

>= | Greater Than or equal to | Checking value stored inside x is equal to or greater than to value stored inside variable y. | x >= y |

<= | Less than or equal to | Checking value stored inside x is less than or equal to value stored inside variable y. | x <= y |

## == Operator

Arithmetic operators are used to perform arithmetic operations on variables and data. it is like +,-*,/ and %

This query focuses on operators like `==`

, `!=`

, `<`

, `>`

, `<=`

, and `>=`

used for comparing values and producing boolean results.

Learners often ask about `&&`

, `||`

, and `!`

operators used to create complex boolean expressions and make decisions based on multiple conditions.

This query focuses on operators like `=`

, `+=`

, `-=`

, `*=`

, `/=`
