Can't see what is wrong

[SirJabalot]

Hi my first post here

I was going to solve a problem and encountered this problem

Can't tell why the long assignment is wrong

Can anyone help me thanks

Error says int is out of bounds

Error says int is out of bounds

Try the following to see what the maximum value is that you use as an int constant:

System.out.println(Integer.MAX_VALUE);

Edit:

Artel shows how to use a long constant, which is the real answer you are looking for.

This will compile without error:

import java.lang.Math;

public class test {
  public static void main (String[] args) {
    long givenNum = 600851475143[COLOR="Red"]l[/COLOR];
    System.out.println(givenNum);
    for (int i = 1; i < Math.floor(givenNum/2); ++i) {
    }
  }
}

I'm kind of a beginner at Java too, so I probably don't know the real explanation, but I think when you assign "600851475143" to a long value, it treats 600851475143 as a literal int, so you have to put an "L" at the end of it so Java will treat it as a long literal instead of an int literal.

I second Artel's recommendation and explanation but with one slight change: always use an upper case L not a lower case l at the end of your long literal as the lower case l is too easily mistaken for a one.

Thank you so much

[SirJabalot]

Ok this is pesky

Even with the L gives an error saying out of int range

[Fubarable]

It works fine for me.

wrote from scratch and it worked
