Question

I am converting a String to byte[] and then again byte[] to String in java using the getbytes() and String constructor,

String message = "Hello World";
byte[] message1 = message.getbytes();

using PipedInput/OutputStream I send this to another thread, where,

byte[] getit = new byte[1000];
pipedinputstream.read(getit);
print(new String(getit));

This last print result in 1000 to be printed… I want the actual string length. How can i do that?

Answer 1

When reading the String, you need to get the number of bytes read, and give the length to your String:

byte[] getit = new byte[1000];
int readed = pipedinputstream.read(getit);
print(new String(getit, 0, readed));

Note that if your String is longer than 1000 bytes, it will be truncated.
