windows - Java reading from binary file -


i have calculated data (floats , integers), written 12mb file this

dataoutputstream os3; os3 = new dataoutputstream(new fileoutputstream(cache.class.getresource("/3w.dat").getpath())); ...... (some loops)      os3.writefloat(f);      os3.writeint(r); os3.close();

and after read way

datainputstream is3; is3 = new datainputstream(new fileinputstream(cache.class.getresource("/3w.dat").getpath())); ...... (same loops)      is3.readfloat();      is3.readint(); is3.close();

so, wrote file once on windows 7. after read while app starts. file reading works fine on windows 7, when try on ubuntu, eof exception (code , file same).

i suspect problem may caused nan values written file.

btw. while debugging figured out on ubuntu reading process runs 15% of loop , throws exception. values reads "0.0", file doesnt contain zeros.

the problem should different of line break between linux , windows. mentioned clark, replace \n \r\n , end of line character resolve this. can use notpad++ simplify work. click on menu :

edit -> eol conversion -> convert unix format

it might problem of encoding. if you'are using windows, default encoding windows-1252 or called cp-1252, specially microsoft thing , cannot recognized on linux. change encoding utf-8 can recognized os. using notpad++:

encoding -> convert utf-8

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.
