Document

Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:Main.java

public static void main(String[] args) throws IOException {
    String outputFile = "new.zip";
    int level = 9;
    int start = 1;

    FileOutputStream fout = new FileOutputStream(outputFile);
    ZipOutputStream zout = new ZipOutputStream(fout);
    zout.setLevel(level);//  ww  w .  j a  v a2 s  .  c  o  m
    for (int i = start; i < args.length; i++) {
        ZipEntry ze = new ZipEntry(args[i]);
        FileInputStream fin = new FileInputStream(args[i]);
        try {
            System.out.println("Compressing " + args[i]);
            zout.putNextEntry(ze);
            for (int c = fin.read(); c != -1; c = fin.read()) {
                zout.write(c);
            }
