Java bitwise error

Hi there,

I have this code

Code:

---

import static java.lang.Long.*;
public class bit {
public static void main(String[] args) {
long number = 0xF000_0000_0000_000FL;
System.out.println(number);
}
}

---

I get this compile error:

bit.java:4: ';' expected
long number = 0xF000_0000_0000_000FL;

Are the _ underscores just used in the examples to make it easier to read what is going on? Or are they used in code and something is wrong with my setup? I am running Ubuntu 11 and JDK 6

java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)


Thanks,
Ajt

The code is correct, but works only in Java 7 !

According to me the problem is underscore. How can we insert underscores between numbers and store them in an numerical data type like long.

So remove the underscore.
