Question

How would it be possible to return the values in the arraylist onto the screen e.g. System.out.println

I was thinking of a for loop e.g.

for (String s : list)
{
    System.out.println(s);
}

But it complains it can’t convert an object to string – how can I convert it to string?

Code:

public static void GetStatsProc(String operation)
{
     try { 
        Process p=Runtime.getRuntime().exec(operation); 
        p.waitFor(); 
        BufferedReader reader=new BufferedReader(new InputStreamReader(p.getInputStream())); 
        String line=reader.readLine(); 
        while(line!=null) 
        { 
            // Add all lines into an array
            ArrayList list = new ArrayList();
            list.add(line);
            System.out.println(line); 
            line=reader.readLine(); 
        } 

     }
     catch(IOException e1) {}
     catch(InterruptedException e2) {}   
}

If your issue is with printing in the for loop, then your list should be declared

ArrayList<String> list = new ArrayList<String>();

and the for loop needs to look like

for (String s : list)
{
    System.out.println(s);
}
