c - What is a clean way to modify arguments inside a function in java? -

-

i interested in doing c code in java:

// sets n's ith bit right, starts 0 void setbit(int* n, int i){    *n = *n | (1 << i); }

however, looks java can't pass addresses, clean approaches?

i thought of 2 approaches, wondering if there better ways it?

approach 1: using array

 // sets n[0]'s ith bit right, starts 0 public void setbit(int[] n, int i){    n[0] = n[0] | (1 << i); }

approach 2: using class

private class data{    int value; }  // sets d.value's ith bit right, starts 0 public void setbit(data d, int i){    d.value = d.value | (1 << i); }

nope, no better way it...

unless you'd traditional java way, is

d = setbit(d, i);  public int setbit(int d, int i) {   return d | (1 << i); }

this in java "modifying arguments function" inherently unclean. clean way find alternative modifying arguments.

(sometimes it'll inevitable, in case workarounds way go. said, if want write method modify(mydata), it's better add modify() method mydata's class.)

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
