    Does this answer your question? [Why does the Java char primitive take up 2 bytes of memory?](https://stackoverflow.com/questions/3956734/why-does-the-java-char-primitive-take-up-2-bytes-of-memory) – sanjeevRm May 24 '21 at 16:04
  • Tip: For working with individual characters, learn to use the methods related to [code point](https://en.wikipedia.org/wiki/Code_point) integers, the number assigned by the Unicode Consortium to each of the 143,859 known characters. The `char` type is obsolete. – Basil Bourque May 24 '21 at 16:26

The char data type in Java originally used for representing 16-bit Unicode. Therefore the size of the char data type in Java is 2 byte

Java uses UTF-16 encoding. C/C++ is using UTF-8.

8 and 16 are the number of bits here.

The evolution of Java was at the time when the Unicode standards had been defined for a very smaller character set. Java was designed for using Unicode Transformed Format (UTF)-16 when the UTF-16 was designed. The char data type in Java is originally used for representing 16-bit Unicode. Therefore the size of the char data type in Java is 2 byte, and same for the C language is 1 byte. Hence Java uses Unicode standard.

Java follows the Unicode standards. Java was developed for worldwide interchange, processing, and display of the written texts of the diverse languages and technical disciplines whereas C and C++ not . So the char size for java is 2 bytes and that for C and C++ is 1 byte.
