is it possible to do a loop based on a if statment? : **ok so im trying to have my code loop if the user clicks no after entering their input **
`import java.awt.event.WindowAdapter;
import javax.swing.JFrame;
import javax.swing.JOptionPane;

	public class Sizer extends WindowAdapter 
	{
			public static void main (String[]args){
				
		
			JFrame m = new JFrame();
			JOptionPane.showMessageDialog(m,"Ok To set the window size you are going to type in the number for each value REMEMBER THE SIZE IS IN PIXELS");
			
			
			String input1= JOptionPane.showInputDialog("Height (suggested under 1080 and above 300)");
			int Height= Integer.parseInt( input1);
			
**after this input i have it set to confirm if this user entered it in correctly if they click yes it keeps going if they click no it exits i want it to have the user type it in again how would i do this** 
			
			int a1 = JOptionPane.showConfirmDialog(m,"Are you sure that this is the correct Height"+ Height);
			if (a1==JOptionPane.YES_OPTION){
			if (a1==JOptionPane.NO_OPTION){
				
			}
			
			String input2= JOptionPane.showInputDialog("Width (suggested under 1920 and above 300)");
			int Width = Integer.parseInt( input2);
				
			
			
			
			JFrame frame = new JFrame();					
			Slop comp = new Slop();
			frame.add(comp);
			frame.setSize(Height,Width);
			frame.setTitle("Slop of a Line");
			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
			frame.setVisible(true);
					}	
			}
	}
