Searching Impl.

This is one bad implementation of the last blog. Need to change a lot of part to run in generic way, I am too lazy :)

import java.util.*;
public class SearchFile
{
public static void main(String args[])
{
try
{
String osName = System.getProperty("os.name" );
System.out.println(osName);
String[] cmd = new String[5];
if( osName.equals( "Windows Vista" ) )
{
cmd[0] = "cmd.exe" ;
cmd[1] = "/C" ;
cmd[2] = "dir *.java /s";
cmd[3] = ">";
cmd[4] = "Hello.txt";
}
/* else if( osName.equals( "Unix" ) )
{
find name filename

...

} */
Runtime rt = Runtime.getRuntime();
System.out.println("Executing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]+ " " + cmd[3]+ " " + cmd[4]);
Process proc = rt.exec(cmd);
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
{
t.printStackTrace();
}
}
}

Look at the search speed after first run. Its simple awesome. But it will create problem if user dont have permission to run a process.
