详解Java无需解压直接读取Zip文件和文件内容

整理文档，搜刮出一个java无需解压直接读取zip文件和文件内容的代码，稍微整理精简一下做下分享。

package test;

import java.io.bufferedinputstream; 
import java.io.bufferedreader; 
import java.io.fileinputstream; 
import java.io.inputstream; 
import java.io.inputstreamreader; 
import java.util.zip.zipentry; 
import java.util.zip.zipfile; 
import java.util.zip.zipinputstream; 


public class aaaa {

  public static void main(string[] args) throws exception {
    try { 
        readzipfile("d:\\ztree.zip"); 
      } catch (exception e) { 
        // todo auto-generated catch block 
        e.printstacktrace(); 
      } 
  }
  
  public static void readzipfile(string file) throws exception { 
      zipfile zf = new zipfile(file); 
      inputstream in = new bufferedinputstream(new fileinputstream(file)); 
      zipinputstream zin = new zipinputstream(in); 
      zipentry ze; 
      while ((ze = zin.getnextentry()) != null) { 
        if (ze.isdirectory()) {
        } else { 
          system.err.println("file - " + ze.getname() + " : " 
              + ze.getsize() + " bytes"); 
          long size = ze.getsize(); 
          if (size > 0) { 
            bufferedreader br = new bufferedreader( 
                new inputstreamreader(zf.getinputstream(ze))); 
            string line; 
            while ((line = br.readline()) != null) { 
              system.out.println(line); 
            } 
            br.close(); 
          } 
          system.out.println(); 
        } 
      } 
      zin.closeentry(); 
    } 
}
