Can I have a Java method have params but doesn't require an arguement to be passed in? -


so have program need call method 2 items in object. thought, if have if user passes in nothing arguement...

x.getitem();

it work , return 1 of 2 items.

but if wanted specific item...

x.getitem(0); or x.getitem(1);

is possible in java? didn't want 0 random , 1 , 2 default...because confusing read later.

it sounds want 2 methods:

private a[] = new a[2]; public getitem() {     return a[new random().nextint(1)]; } public getitem(int index) {     return a[index]; }

given parameters different 2 methods, can use same name (because compiler can distinguish 1 calling depending on actual parameters).

if implement fakey optional parameter, single method more complex - have both ways of looking return value plus logic decide parameter had been omitted. 2 methods nice, clean solution.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
