java - what does getNextEntry() do? -

i have checked java api document, says getnextentry() reads next zip file entry , positions stream @ origin of entry data.

what mean "reads next zip file"? why "next" ?

i have piece of code, what's point of line　ze = zin.getnextentry()？

public void unzip() { seek { fileinputstream fin = new fileinputstream(_zipfile); zipinputstream zin = new zipinputstream(fin); zipentry ze = null; while ((ze = zin.getnextentry()) != null) { log.v("decompress", "unzipping " + ze.getname()); if(ze.isdirectory()) { _dirchecker(ze.getname()); } else { fileoutputstream fout = new fileoutputstream(_location + ze.getname()); (int c = zin.read(); c != -1; c = zin.read()) { fout.write(c); } zin.closeentry(); fout.close(); } } zin.close(); } catch(exception e) { log.e("decompress", "unzip", e); } }

it reads next entry within zip file.

a zip file logically contains main other files - foo.zip can contain files a.txt , b.txt. getnextentry() moves on next file within archive.

(i've never been particularly keen on way zipinputstream modeled using inheritance inputstream, that's different matter.)
