In this tutorial, we are going to learn writing java program to calculate the square root of a given number.

Our Program will take a number from the users as an input, and will return the square root of that number as output.

## What is Square root of Number?

Square root can be defined as **a factor of a number that, when multiplied by itself, gives the original number**.

**For example**

2 is a square root of 4. -2 is also a square root of 4.

because 2*2 = 4 and -2 * -2 = 4
