What is char in java?

char is a reserved word in Java, representing a data type. Unlike other languages, char is 16-bit in Java because Java uses Unicode encoding. However, the 8-bit ASCII code is included in the Unicode encoding, and its value corresponds to 0~127.

Char is one of the eight basic data types of Java.

Char is called "character type" in Java and occupies 2 bytes.

A character constant is a character enclosed in single quotes, and what a character constant stores in memory is the sorting position of the character in the Unicode character set, that is, an integer.
