I have to write a program that tests if a number entered is prime or not.
I have finished all the code to display input prompts and output message
Example: " Enter a number: " - " x is a prime number" - " x is not a prime number" etc
Does anyone know how to write the code to test if a number is prime or not?
I think I would have to divide the input number and check if it is equal to 0. If it is equal to 0 it would not be prime.
Something like this:
division = 2;
input / division
If( division == 0)
System.out.println( result + " is not a prime number");
I'm not sure.
Appreciate any help with this.
