JAVA to DOS

[FurqanAhmed]

I was wondering how could i pass commands to the DOS command line through my JAVA program. e.g

I want to check whether there is a directory "xyz" on c:. but i dont want to do it by using JAVA but rather pass commands to the DOS command line thorough my JAVA program.

I would really appreciate it.

there is an exec() method somewhere, although I honestly can't remember where.. however, I would urge strongly against using this. One of the strong points of java is its cross-platform capability; executing a &quot;dir&quot; command would be in direct conflict with that.<br><br>Also, I'm not understanding why you wouldn't want to use Java to see if there is an &quot;xyz&quot; directory? <p>Liam Morley<br><A HREF="mailto:"></A><br>&quot;light the deep, and bring silence to the world.<br>light the world, and bring depth to the silence.&quot;

Process p;
Runtime r=Runtime.getRuntime();
p=r.exec(&quot;dir c:\xyz&quot;
InputStream is=p.getInputStream();
byte[] b=new byte[2000];//make big enough
int i;
while ((i=in.read(b))!=-1);
String s = new String(b);
if(s.indexOf(&quot;File Not Found&quot==-1)
{
//file exists
}
