# Program to find Quotient And Remainder in Java

The remainder is the integer left over after dividing one integer by another. The quotient is the quantity produced by the division of two numbers. For example,

(7/2) = 3 In the above expression 7 is divided by 2, so the quotient is 3 and the remainder is 1.

### Approach:

Divide the dividend by the divisor using / operator. Both dividend and divisor can be of any type except string, the result will also be computed accordingly. Get the remainder using % operator. Expressions used in program to calculate quotient and remainder:

```quotient = dividend / divisor;
remainder = dividend % divisor;```

Note: The program will throw an ArithmeticException: / by zero when divided by 0.

Explanation:

Consider Dividend = 100 and Divisor = 6 Therefore, Quotient = 100/6 = 16 Remainder = 100%6 = 4

Below are programs that illustrate the above approach:

Program 1:

## java

 `public` `class` `QuotientAndRemainder {`` ` `    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``int` `dividend = ``556``, divisor = ``9``;`` ` `        ``int` `quotient = dividend / divisor;``        ``int` `remainder = dividend % divisor;`` ` `        ``System.out.println(``"The Quotient is = "` `+ quotient);``        ``System.out.println(``"The Remainder is = "` `+ remainder);``    ``}``}`

Output:

```The Quotient is = 61
The Remainder is = 7```

Time Complexity: O(1)

Auxiliary Space: O(1)

Program 2: For a negative number.

## java

 `public` `class` `QuotientAndRemainder {`` ` `    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``int` `dividend = -``756``, divisor = ``8``;`` ` `        ``int` `quotient = dividend / divisor;``        ``int` `remainder = dividend % divisor;`` ` `        ``System.out.println(``"The Quotient is = "` `+ quotient);``        ``System.out.println(``"The Remainder is = "` `+ remainder);``    ``}``}`

Output:

```The Quotient is = -94
The Remainder is = -4```

Time Complexity: O(1)

Auxiliary Space: O(1)

Program 3: This program will throw an ArithmeticException as the divisor = 0.

## java

 `// Class ``public` `class` `QuotientAndRemainder {`` ` `    ``// Main driver method ``    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``int` `dividend = ``56``, divisor = ``0``;`` ` `        ``int` `quotient = dividend / divisor;``        ``int` `remainder = dividend % divisor;`` ` `        ``System.out.println(``" The Quotient is = "``                           ``+ quotient);``        ``System.out.println(``" The Remainder is = "``                           ``+ remainder);``    ``}``}`

Output:

```Exception in thread "main" java.lang.ArithmeticException: / by zero
at QuotientAndRemainder.main(QuotientAndRemainder.java:7)```

Time Complexity: O(1)

Auxiliary Space: O(1)
