一.执行的主函数
public void zip() throws Exception {
//文件输出流
FileOutputStream fos = new FileOutputStream("d:/arch/xxx.xar");
//压缩流
ZipOutputStream zos = new ZipOutputStream(fos);
}
String[] arr = {
"d:/arch/1.jpg",
"d:/arch/2.txt",
"d:/arch/3.xml"
};
for(String s : arr){
addFile(zos , s);
}
zos.close();
fos.close();
System.out.println("over");
public static void addFile(ZipOutputStream zos , String path) throws Exception{
File f = new File(path);
zos.putNextEntry(new ZipEntry(f.getName()));
FileInputStream fis = new FileInputStream(f);
byte[] bytes = new byte[fis.available()];
fis.read(bytes);
fis.close();
zos.write(bytes);
zos.closeEntry();
}
四.解压方法
public void unzip() throws Exception{
//
FileInputStream fis = new FileInputStream("d:/arch/xxx.zip");
//
ZipInputStream zis = new ZipInputStream(fis);
//
ZipEntry entry = null ;
byte[] buf = new byte[1024];
int len = 0 ;
while((entry = zis.getNextEntry()) != null){
String name = entry.getName();
读取文件名，然后执行戒指解压方法
FileOutputStream fos = new FileOutputStream("d:/arch/unzip/" + name);
while((len = zis.read(buf)) != -1){
解压用write
fos.write(buf, 0, len);
}
fos.close();
}
zis.close();
fis.close();
}
