java使用java.util.zip实现文件解压缩，javajava.util.zip,需要引用下面两个包imp

需要引用下面两个包

import java.util.zip.*;import java.io.*;

下面的方法实现解压缩：

public static String Unzip(String inFilePath) throws Exception{    GZIPInputStream gzipInputStream = new GZIPInputStream(new FileInputStream(inFilePath));    String outFilePath = inFilePath.replace(".gz", "");    OutputStream out = new FileOutputStream(outFilePath);    byte[] buf = new byte[1024];    int len;    while ((len = gzipInputStream.read(buf)) > 0)        out.write(buf, 0, len);    gzipInputStream.close();    out.close();    new File(inFilePath).delete();    return outFilePath;}
