This is just part of the code. Where's the
while loop?
LynAs
you don't need while loop. you can do your action with this. to finish taking input you can set a flag.
Scanner scanner = new Scanner(System.in); boolean flag = true; while(flag) { String str = scanner.nextLine(); // Add any condition to set flag = false to exit from while loop } 5 Comments

i dnt knw much abt that operator in c++.What luiggi explain me i rght it @LynAs
Luiggi Mendoza
Kinda. Another way can be
String str = null; while ((str = scanner.nextLine() != null) { ... }.Kick
yes,to exist the loop we need to write break inside it
you can do it either with a GUI style .
import javax.swing.JOptionPane; String Input=JOptionPane.showInputDialog("Title","Message");
