Centering Text in ouput?

Question

I have an issue where i am trying to center output of priority que.
I am not sure how to call the centerformat in display PQ() to format the print statement?
Basically the output has to be like.
BR - Brown
SM - Smith
but centered in the middle of the screen?
class pq
public void displayPQ()
            linein =  queArray[1].getStateRgnNum() + queArray[1].getStateRgn());  
            System.out.println("Region " + queArray[1].getStateRgnNum() + ":" + queArray[1].getStateRgn());        //formating for display output
            System.out.println(" ");
            for(int j=0; j<queArray.length && queArray[j] != null; j++)       //goes through each Priority Queue and displays items
                System.out.println(queArray[j]);
                }//end of for loop
            System.out.println("");
            System.out.println("");
        }//end of displayArray()
class App
public void centerformat(String linein)
            String space = null;
            int spaces = (28 - linein.length())/2;
            for(int i = 0; i < spaces; i++)
                space = space + " ";
        }

Although, looking at your centerformat() method, it has some defects. More so: it isn't doing anything.
