Java使用gzip对字符串进行压缩和解压缩详解编程语言

public static String uncompressString(String str) throws IOException { 

 if (str == null ¦¦ str.length() == 0) { 

 return str; 

 ByteArrayOutputStream out = new ByteArrayOutputStream(); 

 ByteArrayInputStream in = new ByteArrayInputStream(str 

 .getBytes("ISO-8859-1")); 

 GZIPInputStream gunzip = new GZIPInputStream(in); 

 byte[] buffer = new byte[256]; 

 int n; 

 while ((n = gunzip.read(buffer)) = 0) { 

 out.write(buffer, 0, n); 

 // toString()使用平台默认编码，也可以显式的指定如toString("GBK") 

 return out.toString(); 

public static void main(String[] args) throws IOException { 

 String a = compressString("China"); 

 System.out.println(a); 

 System.out.println(a.length()); 

 String b = uncompressString(a); 

 System.out.println(b); 

}
