java - How can i check if there is incoming data from a TCP Socket without receiving it? -


basically need notification, proceed receive data using class datainputstream , method read().

the problem datainputstream not have method check if there read , doing tests read() method interfere further calls read().

i can hack make test reading 1 byte , append further data it, see if there more elegant solution.

datainputstream not have method check if there read

yes does. missed available() method, doesn't return non-zero, depending on you're connected to.

have @ pushbackinputstream.
