为了在文件中搜索字符串并将匹配字符串的行写入另一个文件,对于70MB(压缩状态)的单个zip文件,需要15-20分钟.有没有办法减少它.

我的源代码:

获取Zip文件条目

zipFile = new ZipFile(source_file_name);

entries = zipFile.entries();

while (entries.hasMoreElements())

{ ZipEntry entry = (ZipEntry)entries.nextElement();

if (entry.isDirectory()) 
{ 
continue; 
} 
searchString(Thread.currentThread(),entry.getName(), new BufferedInputStream (zipFile.getInputStream(entry)), Out_File, search_string, stats); }

zipFile.close();

搜索字符串

public void searchString(Thread CThread, String Source_File, BufferedInputStream in, File outfile, String search, String stats) throws IOException

{ 

    int count = 0; 
    int countw = 0; 
    int countl = 0; 
    String s; 
    String[] str; 
    BufferedReader br2 = new BufferedReader(new InputStreamReader(in)); 
    System.out.println(CThread.currentThread()); 

        while ((s = br2.readLine()) != null) 
        { 
            str …
