java - What is the difference between port and localport? -


this question has answer here:

when print object of socket class in java, prints socket details this-- socket[addr=/127.0.0.1,port=49989,localport=10].i know port number.but don't understand why 2 port numbers(port , localport) there ?

as per javadocs

localport - local port socket bound to, or 0 system selected free port.

for other process port number 49989, process using port 10.

imagine telephone call, number ring 49989, telephone number 10

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
