Examples of java.io.ByteArrayOutputStream.toByteArray()

java.io.ByteArrayOutputStream.toByteArray()
Answer the contents of this ByteArrayOutputStream as a byte array. Any changes made to the receiver after returning will not be reflected in the byte array returned to the caller. @return this streams current contents as a byte array.

      out.close();
