Can't properly unzip archive when use ZipInputStream

Question

Hello.
Have some problem with ZipInputStream.
I have two simple tasks:
1. Download zip file from web.
2. Unzip file.
Zipped archive contains four text files.
So, all of the above is simply resolved with a help of ZipFile class, but when i use ZipInputStream, i got only one of four files unzipped in output, where i am did a mistake?
Here is the code:
URL url01=new URL(....);
ZipInputStream zis01=new ZipInputStream(url01.openStream());
            ZipEntry zipEntry;
          while((zipEntry=zis01.getNextEntry())!=null){
                if(!zipEntry.isDirectory()){
                    PrintStream ps01=new PrintStream(new FileOutputStream(zipEntry.getName()),true);
                    BufferedReader bffr01=new BufferedReader(new InputStreamReader(zis01));
                   String line;
                    while((line=bffr01.readLine())!=null){
                        ps01.println(line);
                    ps01.close();
                zis01.closeEntry();
            zis01.close();Edited by: 814785 on Sep 4, 2011 6:03 PM

PrintStream also swallows exceptions.Of course you are right. I handle all necessary exceptions ...You're missing the point. PrintStream doesn't throw them in your code. None of the print() or println() methods throws any exception at all. You have to write extra code. You have to call checkError(). See the Javadoc.Thank you, EJP, I'm already know about this moment. The question is about ZipInputStream behavior, not about how to catch and handle exceptions. There is no exceptions in my code. I tried methods with buffering, without buffering - no success.
As i wrote, the solution is in compression method. ZipFile works - that is enougth, ZipInputStream understrand only old zip archives, to be more exact: method getNextEntry() can't read all entries. You can do your own test, i can send you my archive if you want.
One of other variant of code without any buffers (also doesn't work properly):
ZipInputStream zis01=new ZipInputStream(new FileInputStream("unzipme.zip"));
            ZipEntry zipEntry;
            while((zipEntry=zis01.getNextEntry())!=null){
                if(!zipEntry.isDirectory()){
                    FileOutputStream fos01=new FileOutputStream(zipEntry.getName());
                    int count;
                    while((count=zis01.read())!=-1){
                        fos01.write(count);
                    fos01.close();
                zis01.closeEntry();
            zis01.close();Edited by: user124 on Sep 5, 2011 4:34 PM
