Java input == null why? -

i'm using simple way resources project. i'm using eclipse, , have 'res' folder hold needed files. how load stuff, example 'puppy.png' in res folder (no subfolders):

string path = "/puppy.png"; try {     bufferedimage image = imageio.read(getclass().getresourceasstream(path)); } catch(exception ex) { ex.printstacktrace(); } 

and input==null error, , sometiomes not! not time puppy.png loaded next time won't. classes loads correctly, , other classes error. can explain why can happen, , how can fix it, still use getresourceasstream() method?

please have @ how retrieve image project folder?.

i have mentioned no of ways read image different paths.

you can try one

// read same package  imageio.read(getclass().getresourceasstream("c.png"));  // read absolute path imageio.read(new file("e:\\software\\trainpis\\res\\drawable\\c.png"));  // read images folder parallel src in project imageio.read(new file("images\\c.jpg"));

in case image must in same package class , don't prefix /.
