[JAVA] Decomprimere zip

[morphy79]

boh... cmq ho trovato quest'altro che funziona...

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;



public class ZipHelper {

	// FUNZIONE PER DECOMPRIMERE I FILES ZIP
	public boolean unzip(String pathFile) throws IOException {
		boolean trovatiErrori = true;
		final int BUFFER = 2048;
		try {
			BufferedOutputStream dest = null;
			FileInputStream fis = new FileInputStream(pathFile);
			ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
			ZipEntry entry;
			while((entry = zis.getNextEntry()) != null) {
				int count;
				byte data[] = new byte[BUFFER];
				FileOutputStream fos = new FileOutputStream(entry.getName());
				dest = new BufferedOutputStream(fos, BUFFER);
				while ((count = zis.read(data, 0, BUFFER)) != -1) {
					dest.write(data, 0, count);
				}
				dest.flush();
				dest.close();
			}
			zis.close();
			trovatiErrori = false;
		} catch(Exception e) {
			trovatiErrori = true;
		}
			
		return trovatiErrori;
	}

}
