Is this type of while loop acceptable in Java? -

-

i have seen form used in snippets , wondering if correct implementation of while loop in java: 

while ((bytesread = bin.read(contentbytes)) != -1) {     response = new string(contentbytes, 0, bytesread);     responsebuffer.append(response); }

it reads byte contentbyte , stores in bytesread, if byte read not end of file (-1 indicates end of file) executes statements in loop body. hope helps
