|
This Java tip illustrates a method of retrieving a compressed file from a ZIP file.
This example reads a ZIP file and decompresses the first entry. Developer may modify
the code according to his needs.
try {
// Open the ZIP file
String sourcefile = "source.zip";
ZipInputStream in = new ZipInputStream(new FileInputStream(sourcefile));
// Get the first entry
ZipEntry entry = in.getNextEntry();
// Open the output file
String targetfile = "target";
OutputStream out = new FileOutputStream(targetfile);
// Transfer bytes from the ZIP file to the output file
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
// Close the streams
out.close();
in.close();
} catch (IOException e) {
}
