Java: How to print to a scrollable dialog using a void Print() function?


There are probably a few dozen ways you could do something like this...

Start by taking a look at How to Make Dialogs for more details

The following just creates a html based list of the items...

public void showProfessorList(){
    StringBuilder sb = new StringBuilder(25);
    sb.append("<html>");
    for (int i=0; i < professorList.size();
i++){
       
sb.append(professorList.get(i).getName())).append("<br>");
    }
    JOptionPane.showConfirmDialog(this,
                                  new
JScrollPane(new JLabel(sb.toString),
                                  "Behold",
                                 
JOptionPane.OK_CANCEL_OPTION,
                                 
JOptionPane.PLAIN_MESSAGE);    
}

You could get fancy and use a JList instead, but that comes down to your needs...

Is there another method other than ctrl-p to get print dialog box in datatable print?
If i get your question right, you can do something like this (boostrap icon in this example): <span class="glyphicon glyphicon-print" onclick="javascript:window.print()"></span>

threads and function 'print'
Method start() seems not to work. When I replace for t in types: t.start() for t in types: t.join() with for t in types: t.__run__() It works fine (at least for now, I don't know if it will still when I'll add other commands).

Generic function to print an array in C
Why are you copying at all? What you actually want is to pass a char pointer, that way you can increment it by size from 0 to numElements times, passing it to printFunction each time. Notice, you've actually written a more general function than something that just prints an array. You're effectively writing a 'map' function that maps a function on to an array. Something like this should work (

I am using a recursive function and need to print from within the function just once
You just need to move your print statement out of the reverseDisplay and into main: def reverseDisplay(number): #base case #if number is only one digit, return number if number<10: return number else: result = int(str(number%10) + str(reverseDisplay(number//10))) return result def main(): number = 12345 print reverseDisplay(number) main()

how would I print a pattern then print the reverse pattern next to that pattern?
You have to consider it as one pattern. triangle of numbers as well as blank space. And you have to print whole line and then only you can go to next line (System.out.print(i + " ");). If you print 1st triangle, there is no way you can move last triangle from down to up.
