Can the char type be categorized as an integer?

Question

Just now I read \"char is the only unsigned integral primitive type in Java.\" Does this mean the char is one of the integral types in Java?

Same as in C, recently I

Answer 1

According to the Java Primitive Data Types tutorial:

char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

So yes, it is a 16-bit unsigned integer. Whether you use the type to represent a number or a character is up to you...

Also keep in mind that while the char type is guaranteed to be 16 bits in Java, the only restriction C imposes is that the type must be at least 8 bits. According to the C spec reference from this answer:

maximum number of bits for smallest object that is not a bit-field (byte)

CHAR_BIT 8

So a char in C does not necessarily represent the same range of integer values as a char in Java.
