WebMar 22, 2012 · The SIZE of a Character is the storage needed for a char, which is 16 bit. The length of a string (also the length of the underlying char-array or bytes-array) is the number of characters (or bytes), not a size in bit. That's why you had do to the division by 8 for the size, but not for the length. The length needs to be multiplied by two. WebSep 7, 2014 · The range of a char is 0 to 65535. There are no negative chars. The standard set of characters known as ASCII still ranges from 0 to 127 as always, and the extended 8-bit character set, ISO-Latin-1, ranges from 0 to 255.

WebMar 28, 2010 · A Java char takes always 16 bits. A Unicode character, when encoded as UTF-16, takes "almost always" (not always) 16 bits: that's because there are more than 64K unicode characters. Hence, a Java char is NOT a Unicode character (though "almost always" is). "Almost always", above, means the 64K first code points of Unicode, range … WebJul 7, 2016 · Converting a byte to a char is considered a special conversion. It actually performs TWO conversions.
