我想在我的Java代码中重复相同的过程

Question

大家好，我是初学者，这是我的第3个代码。 基本上，每当控制台向我显示力值时，我都希望它问我“什么是新质量”或类似的东西，或者一遍又一遍地重复相同的过程。谢谢

public static void main(String[] args) {
    int force;
    double Acceleration;
    double Mass;

NewInput();

{
    Scanner myScanner = new Scanner(System.in);

      System.out.print("What is a given Mass"); 

      Mass = myScanner.nextDouble();

}
      Acceleration = 9.8;
      force = (int)(Mass*Acceleration);

      if(force < 0)
          throw new IllegalArgumentException("Must be > 0!");

      System.out.print("Gravitational force for given mass is ");
      System.out.print(force);




      if (force > 1)
      System.out.println(" Newtons");
      else System.out.println("Newton");


}

private static void NewInput() {
    // TODO Auto-generated method stub

}

}
