   JAVA: Convert Byte[] to Char[] and other way.
  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    byte[] decrypt = new byte[length - 2]; char[] data = new char[length - 2];    System.arraycopy(incoming, 2, data, 0, decrypt.length);Encryption.prepareKeys(client); //Decrypt the data for(int i = 0; i < 1; ++i)data = Encryption.decrypt(data); System.arraycopy(decrypt, 0, data, 0, decrypt.length);incoming is also a byte[] bufferit 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] startedjava.lang.ArrayStoreException    at java.lang.System.arraycopy(Native Method)    at server.loginserver.ClientThread.run(ClientThread.java:143)Server thread[C] stoppedim 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.   ;  Maybe an exsample on how to do it ?Im still a bit lost :o   ;  tryed this: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)   ;  found a sollution, takes a bit more ram, but o well.   ;Quote:Original post by NightMarezThe 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.
