Java - Do you want to continue?(Y/N)

I want to write a simple loop for the program to go back and restart it again.

Just a simple 1 question program. Then the system ask if the user want to do it again. If the user inputs Y ... the program will loop it back to the beginning and run the entire program again. If the user inputs N, it exits.

import java.util.Scanner; // show them as code

public class HowToDoLoop {

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

    System.out.print("How much money do you want to have? ");
    double money = input.nextDouble();

    System.out.println("Ok, here is yours $" + money);

    System.out.println("Do you want to continue y or n");

Scanner sc = new Scanner(System.in);

    String response = "";
    do {
        System.out.println("Enter your marks");
        float marks = sc.nextFloat();
        
        if (marks > 90 && marks <= 100) {
            System.out.println("You have scored A grade");
        } else if (marks > 80 && marks <= 90) {
            System.out.println("You have scored B grade");
        } else if (marks > 70 && marks <= 80) {
            System.out.println("You have scored C grade");
        } else if (marks > 60 && marks <= 70) {
            System.out.println("You have scored D grade");
        } else if (marks > 50 && marks <= 60) {
            System.out.println("You have scored E grade");
        } else {
            System.out.println("You have failed");
        }
        System.out.println("do you want to continue y or n?");
        response = sc.next();


    }while(response.equalsIgnoreCase("y"));
}

String c = "";
do{
    System.out.println("How much money do you want to have? ");
    double money = input.nextDouble();

    System.out.println("Ok, here is yours $" + money);

    System.out.println("Do you want to continue y or n");
    c = input.nextLine();

}while(c.equalsIgnoreCase("Y"));

while(true){

    System.out.println("How much money do you want to have? ");
    double money = input.nextDouble();

    System.out.println("Ok, here is yours $" + money);

    System.out.println("Do you want to continue y or n");
    String c = input.nextLine();

   if(c.equalsIgnoreCase("n")){ 
      break;
     }//else continue to loop on any string ;-)

}
