How long is a char in Java?

In Java, char is short for character. It’s 16 bits in size – double that of a byte. Most of the time however, the actual data stored in the char data type doesn’t take up more than 8 bits. The reason Java allows 16 bits is so that all characters in all human languages can be represented.

Is a char 1 or 2 bytes?

How many characters is 2 bytes?

1 byte size of 8 bits can hold a single 8 bit character, hence 2 bytes can hold two 8 bit characters.
