e455. Retrieving a Compressed File from a ZIP File

This example reads a ZIP file and decompresses the first entry.
    try {
        // Open the ZIP file
        String inFilename = "infile.zip";
        ZipInputStream in = new ZipInputStream(new FileInputStream(inFilename));
    
        // Get the first entry
        ZipEntry entry = in.getNextEntry();
    
        // Open the output file
        String outFilename = "o";
        OutputStream out = new FileOutputStream(outFilename);
    
        // 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) {
    }
