JAVA: Convert Byte[] to Char[] and other way.
Author
Hi there.
Dunno if this is correct forum to post this on, but is it possible in java to convert a byte[] to char[] and other way around.
This is for a server.
i got this code
incoming is also a byte[] buffer
it copy incomming to data, decrypt data, copy data to decrypt, then the decryptet data should be in decrypt.
it gives me this error tho :
Server thread[C] started
java.lang.ArrayStoreException
at java.lang.System.arraycopy(Native Method)
at server.loginserver.ClientThread.run(ClientThread.java:143)
Server thread[C] stopped
im using jdk 1.5.0 update 6 and Eclipse as dev tool.
Thanks.
char and byte are different things in Java. char can hold all unicode chars which means it has to have >16 bits.
Quote:arraycopy throws a ArrayStoreException when:
-The src argument and dest argument refer to arrays whose component types are different primitive types.
You want to look into the classes Charset, CharsetDecoder, CharsetEncoder to convert to/from a character buffer and a byte buffer.

tryed this:
however it says :
The method decode(ByteBuffer, CharBuffer, boolean) in the type CharsetDecoder is not applicable
for the arguments (byte[], char[], boolean)
byte[] decrypt = new byte[length - 2]; char[] data = new char[length - 2]; System.arraycopy(incoming, 2, decrypt, 0, decrypt.length); _char.newDecoder().decode(decrypt, data, true);however it says :
The method decode(ByteBuffer, CharBuffer, boolean) in the type CharsetDecoder is not applicable
for the arguments (byte[], char[], boolean)

The point is you use the "array" method to get the underlying charater/byte array.
