import java.util.Scanner;

public class TipCalculator {

public static void main(String [] args) {

double rate1 = 0.1;

double rate2 = 0.15;

double rate3 = 0.2;

Scanner keyboard = new Scanner(System.in);

System.out.print("Enter the purchase price: ");

double total = keyboard.nextDouble();

System.out.printf("10%%: %.2f \n", (total*rate1));

System.out.printf("15%%: %.2f \n", (total*rate2));

System.out.printf("20%%: %.2f \n", (total*rate3));

}

}

I really need help with a simple JAVA program to calculate a tip.. I am very new to JAVA. Going for I.T. but have to take this for the degree. Here are requirements:

 Declare a variable for the purchase price input from the keyboard.

 Declare the necessary variables for the calculations. Since there is

more than one way to do this, I will let you decide what variables to

create.

 Display the three tip rates (use 10%, 15% and 20%) and amounts on

three separate lines, with appropriate labels in text.

 Use: good variable names, indentations, comments, and labels for

the output.

Here is what I have so far:

import java.util.Scanner;



public class TipCalculator

{

public static void main(String [] args)

{

Scanner keyboard = new Scanner(System.in);

double tipRate1, tipRate2, tipRate3;

System.out.println("Enter the purchase price: ");

double subTotal = keyboard.nextInt ();

System.out.println("Enter how much would you like to tip: ");

double tip = 0;

tipRate1 = 0.1;

tipRate2 = 0.15;

tipRate3 = 0.2;





subTotal = keyboard.nextInt ();

System.out.print("tip rate");

System.out.println( subTotal + "tip: " + tip);

System.out.printf("A dollar amount: $%.2f", tipRate1);







}

}



Any help would be greatly appreciated.
