Java : Char vs String byte size

getBytes() outputs the String with the default encoding (most likely ISO-8859-1) while the internal character char has always 2 bytes. Internally Java uses always char arrays with a 2 byte char, if you want to know more about encoding, read the link by Oded in the question comments.

I would like to say what i think,correct me if i am wrong but you are finding the length of the string which is correctly it is showing as 1 as you have only 1 character in the string. length shows the length not the size . length and size are two different things.

check this Link.. you are finding the number of bytes occupied in the wrong way
