How to implement an input in a loop

Question

I wanted to create a loop where I can input my name using a Scanner, but the system keeps spamming "Gimme your name" and doesn't leave me the chance to input my name. I want the system to output "Gimme your name" and wait for my input.

Scanner sc = new Scanner(System.in);
char reponse = 'O';
name = sc.nextLine();
while (reponse=='O')

    System.out.println("Gimme your name! ");
    name = sc.nextLine();
    System.out.println("Hello "+name+"How are you doing ? \n Wanna retry ? (O/N)" );
    reponse = sc.nextLine().charAt(0);

Your while only applies to System.out.println("Gimme your name! ");. Missing braces around your block — lurker

Try putting open close brackets around the while statement:

   char reponse = 'O';
    name = sc.nextLine();
    while (reponse=='O') {

        System.out.println("Gimme your name! ");
        name = sc.nextLine();
        System.out.println("Hello "+name+"How are you doing ? \n Wanna retry ? (O/N)" );
        reponse = sc.nextLine().charAt(0); ``` 

    }

Because there is not a open and close bracket, the way the code was written may be read from the compiler like:

while (respose == 'O') System.out.println("Gimme your name! ");

The ending semicolon would "combine" the two lines into one, per se.

Include the open and closed bracket after the while loop and at the end of the looping statements to fix.
