Is a Number a Prime Number

Prime Number?
​

Finding out if a number is a prime number can be tricky, but heres the code to add to yor java application that will work it out for you.

[java]
public class IsPrime {

public static void main(String[] args)
{
int i = 23;
boolean isprime = true;

for(int k=2; k<i; k++)
{
if(i%k==0)
isprime = false;
}

System.out.println(isprime);
}
}
[/java]

Let me know if your struggling

I have a little more than 10 posts.

Does return true/false actually show true and false?

There you go, updated OP.
That will display true or false depending on the value of i.
