What is the numerical range of char?

0 to 32767
0 to 65535
-256 to 255
-32768 to 32767

Correct Answer: 0 to 65535

Explanation:

The char type is integral but unsigned. The range of a variable of type char is from 0 to 2¹⁶-1 or 0 to 65535. Java characters are Unicode, which is a 16-bit encoding capable of representing a wide range of international characters. If the most significant nine bits of a char are 0, then the encoding is the same as seven-bit ASCII.
