如何用java或者批处理命令　实现解压一个rar或zip文件 到选择的目录下 并生成桌面快捷方式

/**
* 解压课件包中的某个课件
* @param zipFilePath 课件包路径
* @param outDirPath 输出目录路径
* @return 解压出来文件的绝对路径，失败返回null
* @throws IOException
*/
public String decompressAllFileToDir(String zipFilePath, String outDirPath) throws IOException {
ZipFile zip = new ZipFile(zipFilePath, "GBK");

@SuppressWarnings("unchecked")
Enumeration entries = zip.getEntries();
if (entries == null) {
return null;

java.io.File file = new java.io.File(outDirPath);
String path = file.getAbsolutePath();

return null;
}
while(entries.hasMoreElements())

ZipEntry entry = entries.nextElement();

InputStream is = zip.getInputStream(entry);
java.io.File tempFile = new java.io.File(nameInZip);
FileOutputStream fos = new FileOutputStream(new StringBuilder(path).append("/").append(tempFile.getName()).toString());
byte[] bytes = new byte[MAX_BUFFER];
int size = 0;

}

return zipFilePath;
