Using Java to implement Zip compressed file and directory program code (b) __java

Today wrote a Java compression function, you can achieve the compression of files and directories.

Because Java.util.zip.ZipOutputStream has the Chinese garbled problem, therefore uses the Org.apache.tools.zip.ZipOutputStream.
Here's the code:
Java code
Package net.szh.zip;

Import Java.io.BufferedInputStream;
Import Java.io.File;
Import Java.io.FileInputStream;
Import Java.io.FileOutputStream;
Import java.util.zip.CRC32;
Import Java.util.zip.CheckedOutputStream;

Import Org.apache.tools.zip.ZipEntry;
Import Org.apache.tools.zip.ZipOutputStream;

public class Zipcompressor {
static final int BUFFER = 8192;

Private File ZipFile;

Public Zipcompressor (String pathName) {
ZipFile = new File (pathName);
}

public void compress (String srcpathname) {
File File = new file (srcpathname);
if (!file.exists ())
throw new RuntimeException (Srcpathname + "does not exist.) ");
try {
FileOutputStream FileOutputStream = new FileOutputStream (ZipFile);
Checkedoutputstream cos = new Checkedoutputstream (FileOutputStream,
New CRC32 ());
Zipoutputstream out = new Zipoutputstream (COS);
String basedir = "";
Compress (file, out, basedir);
Out.close ();
catch (Exception e) {
throw new RuntimeException (e);
}
}

private void compress (file file, zipoutputstream out, String basedir) {
/* Determine whether the directory or file * *
if (File.isdirectory ()) {
System.out.println ("Compression:" + Basedir + file.getname ());
This.compressdirectory (file, out, basedir);
} else {
System.out.println ("Compression:" + Basedir + file.getname ());
This.compressfile (file, out, basedir);
}
}

/** Compress a directory * *
private void Compressdirectory (File dir, zipoutputstream out, String basedir) {
if (!dir.exists ())
Return

file[] files = dir.listfiles ();
for (int i = 0; i < files.length; i++) {
/* Recursive * *
Compress (Files[i], out, Basedir + dir.getname () + "/");
}
/** Compress a file */
private void Compressfile (file file, zipoutputstream out, String basedir) {
if (!file.exists ()) {
Return
}
try {
Bufferedinputstream bis = new Bufferedinputstream (
New FileInputStream (file));
ZipEntry entry = new ZipEntry (Basedir + file.getname ());
Out.putnextentry (entry);
int count;
byte data[] = new Byte[buffer];
while (count = bis.read (data, 0, BUFFER)!=-1) {
Out.write (data, 0, count);
}
Bis.close ();
catch (Exception e) {
throw new RuntimeException (e);
}
}
}

Package net.szh.zip;

Import Java.io.File;
Import Java.io.FileInputStream;
Import Java.io.FileOutputStream;
Import java.util.zip.CRC32;
Import Java.util.zip.CheckedOutputStream;

Import Org.apache.tools.zip.ZipEntry;
Import Org.apache.tools.zip.ZipOutputStream;

public class Zipcompressor {

Private File ZipFile;

Public Zipcompressor (String pathName) {

}

public void compress (String srcpathname) {

if (!file.exists ())
throw new RuntimeException (Srcpathname + "does not exist.) ");
try {
FileOutputStream FileOutputStream = new FileOutputStream (ZipFile);
Checkedoutputstream cos = new Checkedoutputstream (FileOutputStream,
New CRC32 ());
Zipoutputstream out = new Zipoutputstream (COS);
String basedir = "";
Compress (file, out, basedir);
Out.close ();
catch (Exception e) {
throw new RuntimeException (e);
}
}

private void compress (file file, zipoutputstream out, String basedir) {

This.compressdirectory (file, out, basedir);
} else {
System.out.println ("Compression:" + Basedir + file.getname ());
This.compressfile (file, out, basedir);
}
}

/** Compress a directory * *
private void Compressdirectory (File dir, zipoutputstream out, String basedir) {
if (!dir.exists ())
Return

file[] files = dir.listfiles ();
for (int i = 0; i < files.length; i++) {
/* Recursive * *
Compress (Files[i], out, Basedir + dir.getname () + "/");
}
/** Compress a file */
private void Compressfile (file file, zipoutputstream out, String basedir) {
if (!file.exists ()) {
Return
}
try {
Bufferedinputstream bis = new Bufferedinputstream (
New FileInputStream (file));
ZipEntry entry = new ZipEntry (Basedir + file.getname ());
Out.putnextentry (entry);
int count;
byte data[] = new Byte[buffer];
while (count = bis.read (data, 0, BUFFER)!=-1) {
Out.write (data, 0, count);
}
Bis.close ();
catch (Exception e) {
throw new RuntimeException (e);
}
}
}

It turns out that you can use Ant's Org.apache.tools.ant.taskdefs.Zip to make it easier.
Java code
Package net.szh.zip;

Import Java.io.File;

Import Org.apache.tools.ant.Project;
Import Org.apache.tools.ant.taskdefs.Zip;
Import Org.apache.tools.ant.types.FileSet;

public class Zipcompressorbyant {

Private File ZipFile;

Public zipcompressorbyant (String pathName) {
ZipFile = new File (pathName);
}

public void compress (String srcpathname) {
File Srcdir = new file (srcpathname);
if (!srcdir.exists ())
throw new RuntimeException (Srcpathname + "does not exist.) ");

Project PRJ = new Project ();
Zip zip = new zip ();
Zip.setproject (PRJ);
Zip.setdestfile (ZipFile);
Fileset fileset = new Fileset ();
Fileset.setproject (PRJ);
Fileset.setdir (Srcdir);
Fileset.setincludes ("**/*.java"); Include which files or folders eg:zip.setIncludes ("*.java");
Fileset.setexcludes (...); Which files or folders are excluded
Zip.addfileset (Fileset);

Zip.execute ();
}
}

Package net.szh.zip;

Import Java.io.File;

Import Org.apache.tools.ant.Project;
Import Org.apache.tools.ant.taskdefs.Zip;
Import Org.apache.tools.ant.types.FileSet;

public class Zipcompressorbyant {

Private File ZipFile;

Public zipcompressorbyant (String pathName) {
ZipFile = new File (pathName);
}

public void Compress (String srcpathname) {
File srcdir = new file (srcpathname);
if (!srcdir.exists ())
Throw The new RuntimeException (Srcpathname + "does not exist.) ");

Project PRJ = new Project ();
Zip zip = new zip ();
Zip.setproject (PRJ);
Zip.setdestfile (ZipFile);
Fileset fileset = new Fileset ();
Fileset.setproject (PRJ);
Fileset.setdir (Srcdir);
//fileset.setincludes ("**/*.java"), including which files or folders eg:zip.setIncludes ("*.java");
//fileset.setexcludes (...); Which files or folders to exclude
Zip.addfileset (fileset);

Zip.execute ();
}
}
Test
Java Code
Package Net.szh.zip public class Testzip {
public static void Main (string[) a RGS) {
Zipcompressor ZC = new Zipcompressor ("E:" "Szhzip.zip");
Zc.compress ("E:" "Test");

Zipcompressorbyant zca = new Zipcompressorbyant ("E:" "Szhzipant.zip");
Zca.compress ("E:" "Test");
}
}
