用JAVA读取rar文件中文件的名称和打开文件读出文件的内容

package com;
import java.util.*;
import java.lang.Runtime.*;
import java.io.*;

public class UnRarTest {
public static void main(String[] args) throws Exception
{
   Scanner in=new Scanner(System.in);
   System.out.println("输入你要解压的文件(包括路径,后缀)");
   String filename=in.nextLine();
   showList(filename);
  
   System.out.println("从中选择你要打开的文件");
   String nfilename=in.nextLine();
   unRar(nfilename);  
}
/*D:\\Program Files\\WinRAR\\为我的WinRAR目录
* 根据自己的情况改下
* 得到RAR文件目录
*/
   public static void showList(String compress)throws Exception 
   {
    Runtime rt =Runtime.getRuntime();
    Process p = rt.exec("D:\\Program Files\\WinRAR\\UnRAR.EXE l " + compress );
    InputStream fis = p.getInputStream();//获得子进程的输入流
    BufferedReader in=new BufferedReader(new InputStreamReader(fis));
    String line;
    while((line=in.readLine())!=null)
    {
     System.out.println(line);
    }
            in.close();
    fis.close();
   
   }
   /*
   * 显示你要打开的文件内容
   */
   public static void unRar(String ncompress)throws Exception
   {
    Runtime rt =Runtime.getRuntime();
    Process p = rt.exec("D:\\Program Files\\WinRAR\\UnRAR.EXE e -o+ -p- " + ncompress );//将指定的压缩文件解压到D:\Program Files\WinRAR\目录下
    BufferedReader in=new BufferedReader(new FileReader("D:\\Program Files\\WinRAR\\"+ncompress)); 
    String line;
    while((line=in.readLine())!=null)
    {
     System.out.println(line);
    }
   
    in.close();
   }


}

 

 

都在控制台实现此功能
