Thread: Display in JOptionPane

I have my code done, but i need to display the results with JOptionPane. Is there a way to store the result of the for loops so i can recall it with JOptionPane.showmessage()?
thanks

 
import javax.swing.JOptionPane;
 
public class pyramid {
	public static void main(String[] args) {
		String LinesString = JOptionPane.showInputDialog("Enter the number of lines: ");
		int row = Integer.parseInt(LinesString);
 
		int spaces = row - 1; 
		int numPrint = 1; 
 
 
		for(int x = 0; x < row; x++){  
		  for(int y = 0; y < spaces; y++){  
		   System.out.print("   ");}  
		    for(int i = numPrint; i > 0; i--){ 
		      System.out.printf("%3d",i);  
		}  
		   for(int z = 1; z < numPrint; z++){   
 
		   System.out.printf("%3d",z + 1);  
 
		}  
		numPrint += 1;  
		spaces -= 1;  
		System.out.println();
 
		}
	}
}

Your code with its inconsistent formatting is next to impossible to read. Please go through

You can store each line as an element of a String array and pass the array as the message parameter to JOptionPane.showMessageDialog

It depends if you like a JOptionPane for each iteration of the loop or not.

If you do, I have no clue how to do the %3d with JOptionPane, but you'd

do this:

JOptionPane.showMessageDialog(Component parent, Object message, String title, int messageType);

message Types are JOptionPane.PLAIN_MESSAGE, JOptionPane.WARNING_MESSAGE; JOptionPane.INFORMATION_MESSAGE, JOptionPane.QUESTION_MESSAGE, and JOptionPane.ERROR_MESSAGE.

You're probably using JOptionPane.INFORMATION_MESSAGE.
