Why cannot I assign value to a long variable that is between 2^64 and 2^32?

I am trying to test the difference between int and long data types and I've learned that int has 32 bits whereas long has 64 bits. According to this, long data type's maximum value is 9,223,372,036,854,775,807. I am only using a 13-digit number however I am getting this error:

error: integer number too large: 2147483645234

long exceedLong = 2147483645234;

I thought a long variable should be able to handle that value. I'm using JDK and JRE version 8 and I'm compiling and running the code in command prompt, using javac and java.

add a `L` to the long value – Murat Karagöz Aug 18 '17 at 14:26

literal number declaration without floating part are by default `int`. Suffix it with `l` or `L` to declare a long : `long exceedLong = 2147483645234L;` – davidxxx Aug 18 '17 at 14:27
simply try to use **L** at end of your number long exceedLong = 2147483645234L; – Aug 18 '17 at 14:31
