Zlib压缩算法在java上的应用

JAVA实现

　　在JDK中，在java.util.zip包中已经内置了ZLIB的实现，示例代码如下：

1//解压
2 public String decompressData(String encdata) {
3 try {
4 ByteArrayOutputStream bos = new ByteArrayOutputStream();
5InflaterOutputStreamzos = newInflaterOutputStream(bos);
6 zos.write(convertFromBase64(encdata));
7 zos.close();
8 return new String(bos.toByteArray());
9 } catch (Exception ex) {
10 ex.printStackTrace();
11 return "UNZIP_ERR";
12 }
13 }
14
15 //压缩
16 public String compressData(String data) {
17 try {
18 ByteArrayOutputStream bos = new ByteArrayOutputStream();
19 DeflaterOutputStream zos = new DeflaterOutputStream(bos);
20 zos.write(data.getBytes());
21 zos.close();
22 return new String(convertToBase64(bos.toByteArray()));
23 } catch (Exception ex) {
24 ex.printStackTrace();
25 return "ZIP_ERR";
26 }
27 }

不过我Android里面InflaterOutputStream好像不支持 我还没想到如何在android里实现
