Read this:

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).

P.S. Is this question worth asking? Just 5 seconds of google'ing...

My guess is that it seems the OP asking about the size of Character, not char (though it's not really clear). Though I believe those should be the same.

A Java char is 16 bits, and holds a code unit for UTF-16–encoded Unicode code points.

Character.MIN_VALUE is 0 and Character.MAX_VALUE is 65535.

Strings are UTF-16 encoded and can give you 16-bit unsigned char or code points of type int.
