Is there a way to ping in
I need to have echo response times of some addresses but I could not find a spesific class that does ping.

Ping is implemented using a low-level protocol named ICMP, and Java doesn't support it directly. You have three choices:
Use the UDP 'echo' protocol or something similar instead of real 'ping', like
Execute an external 'ping' program using Runtime.exec(); or
Use JNI to interface to native code that implements ICMP ping.
