上面的程序是一个解压缩操作，在d盘的根目录下有压缩文件zip.test,压缩实体是一个文件夹下面的4个文件
运行上面的程序 ，提示的错误:
解压缩test\3.txt名字
Exception in thread "main" java.io.IOException: 系统找不到指定的路径。
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.createNewFile(File.java:947)
at IO.ZipInputStreamDemo.main(ZipInputStreamDemo.java:25)
这儿的路径没问题，为什么总是找不到路径？
------解决方案--------------------
修正一下，刚才的程序如有先前有文件夹了可能会报错，用下面这个
- Java code
import java.io.*;import java.util.zip.*;public class ZipInputStreamDemo { public static void main(String[] args) throws Exception { File file=new File("d:" +File.separator+"test.zip"); File outFile=null; InputStream in=null; OutputStream out=null; ZipFile zf=new ZipFile(file); ZipInputStream zips=new ZipInputStream(new FileInputStream(file)); ZipEntry entry=null; while((entry=zips.getNextEntry())!=null){ System.out.println("解压缩"+entry.getName()+"名字"); outFile=new File("d:" +File.separator +entry.getName() ); /*if(!outFile.getParentFile().exists()){ outFile.mkdir(); }*/ if (entry.isDirectory()) { if (! outFile.exists()) { outFile.mkdir(); } else { continue; } } if(!outFile.exists()){ outFile.createNewFile(); } in=zf.getInputStream(entry); out=new FileOutputStream(outFile); int temp=0; while((temp=in.read())!=-1){ //文件结束标识为-1 out.write(temp); } in.close(); out.close(); } //in.close(); //out.close(); }}
