java - Right place to flush the object -


i have written small piece of code printing:

        bufferedwriter out = null;         try {             out = new bufferedwriter(new outputstreamwriter(                     new fileoutputstream(filedescriptor.out), "ascii"), 512);             out.write(msg + '\n');             out.flush();         } catch (unsupportedencodingexception e) {              throw new illegalstateexception(                     "test failed ",                     e);         } catch (ioexception e) {              throw new illegalstateexception(                     "test failed", e);         } {             if (out != null) {                 out = null;             }         }

flushing of obj done in try block only. way or should flush object in block?

use modern syntax if can , don't worry that. closing automatically flush it, use try-with-resources syntax. code shorter , more readable:

    try(bufferedwriter out = new bufferedwriter(new outputstreamwriter(                 new fileoutputstream(filedescriptor.out), "ascii"), 512)) {         out.write(msg + '\n');     } catch (unsupportedencodingexception | ioexception e) {         logger.info("test failed due exception.");         throw new illegalstateexception("test failed", e);     }

see more try-with-resources if unfamiliar syntax.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
