Compile error Enum

[Lorenzo Tagliaferro]

Hi all,

I'm trying to compile a simple enum:

import static java.lang.System.out;

enum Num {

	Num1(9223372036854775797),
	Num2(Long.MAX_VALUE - 985),
	Num3(Long.MAX_VALUE - 130);
	
	Num(long l){
		this.l = l;
		out.println("Num constructor called!");
	}
	
	private long l;
	
	public long getL(){
		return l;
	}
}

public final class Elaborator {

	public static void main (String[] args){	
		for(Num n : Num.values())
			out.println(n + " " + n.getL());
		
	}
}

I receive 1 error:


Elaborator.java:5: integer number too large: 9223372036854775797
Num1(9223372036854775797),
^
1 error


I don't understand why!!

Thanks!

Non floating point numeric literals in Java are considered to be integers and that number is too large to be an integer. If you want it to be considered a long put L on the end

Num1(9223372036854775797L)

Note - always use a capital L for this as a lowercase l might be mistaken for the digit 1.
