Re: How to make a system call in Java

[Yuet Sim Lee]

I tried the following code:

   import java.io.*;

   public class runabl {
       public static void main( String[] args )
    {
       try{
        Runtime rt = Runtime.getRuntime();

        Process prcs = rt.exec( "a.out" );
        System.out.println("Inside try");
        System.out.println(prcs);
           }
       catch( Exception e ) {
         System.out.println("Catch something");
         System.out.println(e);
       }
     }
   }

However, the output is :

   Inside try
   java.lang.UNIXProcess@156d6e

instead of the result from typing "a.out" directly.
