DOing this stuff for school in notepad to lazy to install jdk and jvm and yadda yadda so if it works, or could use some doctoring much appreciated, I have a couple more I want to post.

Ah I remember learning this in Java class last year. The AP test was HELLA hard.

[hogworth]

Yeah I havn't done anything all year so I expect 2 weeks of severe work will pass me.

I could use some help from someone here.
HERes The badly worded question
A Prime number is an interger greater than 1 divisible by only itself and 1. The first seven prime numbers are 2,3,5,7,11, 13 and 17. Write a program that takes in a number from the user and prints out whether their number is prime or not.

I think I've got the math down its the syntax that getting to me, I think I can use an If loop

if (i%==0)
exit loop
else
x=x-1

I'm not asking you write the code for me but getting me started would help, I'm dying here and it would be much appreciated.

[Kohaku]

Here's my source code:

public class Prime
{

public static void main(String[]args)
{


EasyReader IO = new EasyReader();
System.out.print("Enter a number: ");
int num= IO.readInt();
if (num%2==1)
{

System.out.println("The number " + num + " is prime.");
}
else
System.out.println("The number " + num + " is not prime");

}
}

Ok, Forgive me if I ask something stupid or beat a dead horse but I'm just trying to understand your code, it looks pretty straight forward but I dunno what easy reader is.
-------------------------------------------------
I can just go through the whole
import TerminalIO.KeyboardReader
KeyboardReader reader = new KeyboardReader();

int(or double?) x; // number 1
to bypass this I don't want elegant code I need straightforward gets the job done.
EasyReader IO = new EasyReader();


System.out.print("Enter a number: ");
int num= IO.readInt();
-----------------------------------------------------

if (num%2==1)
{

the input number is divided by two modulus, and if the remainder is 1 then the number is Prime, but does this simple thing really work with all numbers?

-----------------------------------------------------
System.out.println("The number " + num + " is prime.");
}
else
System.out.println("The number " + num + " is not prime");

}
}


Again Thank you.

[Kohaku]

EasyReader is just an code for imputing numbers and/or words. Google EasyReader and the .java file should be the first thing that pops up. It makes imputing so much easier. You don't need the import TerminalIO at the top. For the number, using int instead of double is fine since you use whole numbers anyway. And yes, this code should work since I compiled it and tested myself. Give it a shot.

Awesome thanks alot.
