SampleCode:

/**
* @param command the string containing the command to execute
*/
public void executeCommand(String command)
{
Process p;
try{
p=Runtime.getRuntime().exec(command);
BufferedReader in=new BufferedReader(new InputStreamReader(p.getInputStream()));

int i=p.waitFor();
if(i==0)
System.out.println("Command executed successfully");
else
System.out.println("Failed to execute command");
String s=null;

while((s=in.readLine())!=null)
System.out.println(s);
}

for example, ls

import java.io.InputStream;
import java.io.IOException;

public class foo
{
   public foo()
   {
       Runtime rt = Runtime.getRuntime();
       Process p = null;
       try
       {
           p = rt.exec( "ls -l" );
       }
       catch ( IOException ioe )
       {
           System.out.println( "Error executing file" );
       }
       InputStream output = p.getInputStream();
       System.out.println( output );
   }

   public static void main( String args[] )
   {
       foo f = new foo();
       System.exit( 0 );
   }
}
