There are many ways to check if a number is prime or not, but the most common of them is the trial division, which is what we will see in this tutorial. In my opinion, these kinds of programs are their first steps towards algorithmic understanding. You first come up with a solution,...
Second, it is preferable to take the input as a double or long instead of int to square a number in Java so that we can apply the logic for any number that the user enters. Try the above programs by changing the data type to double. Let us know about your results and understanding...
