Java code - number of files in a JAR -

i want find number of files jar contains. there way without looping through this:

while (enumentries.hasmoreelements()) {     enumentries.nextelement();     count++; } 

i want have number of files before loop through entries. seems not elegant loop through them twice.

you can use size() count number of entries that's loop return.

uses

jarfile f = new jarfile(new file("path.jar")); system.out.println(f.size());
