Explanation

Java's long type is a 64-bit signed integer. The range is -2^63 to (2^63 - 1), which equals -9223372036854775808 to 9223372036854775807.

AI explanation

Java's long is a 64-bit signed two's-complement integer type, so its range runs from -2^63 to 2^63 - 1. The int type is the one bounded by -2^31 to 2^31 - 1, and there is no unsigned equivalent in standard Java for these primitives, so the -2^63 to 2^63 - 1 range is correct for long.
