Why does JLS state that the largest int literal is 2147483648?

java, jls

Solution

The largest decimal literal of type int is 2147483648 (231).

All decimal literals from 0 to 2147483647 may appear anywhere an int literal may appear.

It is a compile-time error if a decimal literal of type int is larger than 2147483648 (231), or if the decimal literal 2147483648 appears anywhere other than as the operand of the unary minus operator (§15.15.4).

Problem

JLS `3.10.1. Integer Literals` http://docs.oracle.com/javase/specs/jls/se7/html/jls-3.html#jls-3.10.1 states ``` The largest decimal literal of type int is 2147483648. ``` At the same time this line ``` int x = 2147483648; ``` produces a compile error ``` The literal 2147483648 of type int is out of range ``` Is JLS wrong?
