Tip Calculator Help in Java?

Question

import java.util.Scanner;

public class TipCalc
{
public static void main(String[] args);
    Scanner cin = new Scanner(System.in);
{
    System.out.println("Tip Calculator");
    System.out.println("===============");
    System.out.print("Enter check subtotal (9.25): ");
    double subtotal = cin.nextDouble();
    System.out.print("Enter gratuity percentage (20): ");
    int gratuity = cin.nextInt();
    System.out.println("");
    double gratuityAmount = gratuity * .01 * subTotal;
    System.out.println("\tGratuity: " + gratuityAmount);
    double total = gratuityAmount + subTotal;
    System.out.println("\tTotal: $" + total);
}
}

I get these errors: 3 errors found: [line: 5] Error: missing method body, or declare abstract [line: 15] Error: cannot find symbol symbol: variable subTotal location: class TipCalc [line: 17] Error: cannot find symbol symbol: variable subTotal location: class TipCalc I just started to learn Java. I am confused on to what went wrong. Any advice?

Answer 1

Your main method lacks a body.

  public class TipCalc
  {
    public static void main(String[] args)
    {
      Scanner cin = new Scanner(System.in);
      System.out.println("Tip Calculator");
      System.out.println("===============");
      System.out.print("Enter check subtotal (9.25): ");
      double subtotal = cin.nextDouble();
      System.out.print("Enter gratuity percentage (20): ");
      int gratuity = cin.nextInt();
      System.out.println("");
      double gratuityAmount = gratuity * .01 * subTotal; //Note: subTotal variable isn't defined
      System.out.println("\tGratuity: " + gratuityAmount);
      double total = gratuityAmount + subTotal;
      System.out.println("\tTotal: $" + total);
    }
  }

That should help your formatting errors.

The method body comes immediately after such as: public void doSomething(){ <-begins body and ends with-> }

In the beginning, methods are only briefly discussed but you will go more in-depth and get the hang of it.
