If we want to calculate square root, we can use Math.sqrt() method. It is simple. Now do you know how to write such a method by yourself? Here is the equation you need. The first sqrt number should be the input number / 2. Using the equation, we can come up with a Java Square Root method by ourselves. 1) Program 1: Prompting user for entering the side of the square 2) Program 2: Side of the square is specified in the program’ s source code. Program 1: /** * @author: BeginnersBook.com * @description: Program to Calculate Area of square.Program * will prompt user for entering the side of the square. In Java write a program to compute the square root of a number. DO NOT USE any math libraries/methods in this program. You will be using the Babylonian method (a.k.a. Heron’s method) to approximate the square root.

I am trying to write a code to return a square of a number

I think my method is basically complete but then I have trouble with compiling,

here is my code

Change print square(num); to System.out.println(square(num)); or to square(num); Although, what you're doing makes no sense because you actually print the number in your method as well. Try changing your code to this:

There isn't a print statement in Java - you need to use the method System.out.println(square(num));

Although, actually, your square method is writing the squared number to STDOUT anyway, so you don't need to do any more printing - just square(num); would be enough.

you're calling a method, 'print' does not make any sense there.

The process of finding the square root of a number can be divided into two steps. One step is to find integer part and the second one is for fraction part.

Algorithm

1. Define value n to find the square root of.
2. Define variable i and set it to 1. (For integer part)
3. Define variable p and set it to 0.00001. (For fraction part)
4. While i*i is less than n, increment i.
5. Step 4 should produce the integer part so far.
6. While i*i is less than n, add p to i.
7. Now i have the square root value of n.
