Question

I have the problem in bold below. I am completely confused. I am hoping that I will see how you did this and will be able to follow it. Please remember that I have just started this so please don't use any complex features that an absolute beginner (like me) wouldn't know.

Additional information:

  /*This is what everyone owes before tax and tip:

    Person 1: $10

    Person 2: $12

    Person 3: $9

    Person 4: $8

    Person 5: $7

    Person 6: $15

    Person 7: $11

    Person 8: $30

    */

package Tip02;

public class Calculator {

  public double tax = .05;

  public double tip = .15; //Change tax and tip if you prefer different values

  public double originalPrice = 0;

   

  public void findTotal(){

    //Calculate an individual's total after tax and tip

    //Print this value

  }

}

Please give me a solution and (explanation if possible).

Package Tip02;

public class CalculatorTest {

  public static void main(String[] args) {

    //Instantiate a Calculator object

    Calculator calc = new Calculator ();

    

     //Access the Calculator object's fields and methods

    //to find the total for each member of the birthday party

         /*This is what everyone owes before tax and tip:

    Person 1: $10

    Person 2: $12

    Person 3: $9

    Person 4: $8

    Person 5: $7

    Person 6: $15 (Alex)

    Person 7: $11

    Person 8: $30

Answer 1

input code:

package:

Main file:

output:

code:

package:

package Tip02;
class Calculator {
/*declare the variables*/
public double tax = .05;
public double tip = .15; //Change tax and tip if you prefer different values
public double originalPrice = 0;
/*find Total method*/
public void findTotal()
{
/*find and print Total*/
System.out.println(" Total = "+String.format("%.2f",(originalPrice+originalPrice*tax+originalPrice*tip)));
}

}

main file:

import Tip02;

public class CalculatorTest {

public static void main(String[] args) {
  
/*make Calculator object*/
Calculator calc = new Calculator ();
/*for Person 1 Calculate total bill*/
System.out.print("Person 1");
/*set value of originalPrice*/
calc.originalPrice=10;
/*call findTotal method*/
calc.findTotal();
  
/*for Person 2 Calculate total bill*/
System.out.print("Person 2");
/*set value of originalPrice*/
calc.originalPrice=12;
/*call findTotal method*/
calc.findTotal();
  
/*for Person 3 Calculate total bill*/
System.out.print("Person 3");
/*set value of originalPrice*/
calc.originalPrice=9;
/*call findTotal method*/
calc.findTotal();
  
/*for Person 4 Calculate total bill*/
System.out.print("Person 4");
/*set value of originalPrice*/
calc.originalPrice=8;
/*call findTotal method*/
calc.findTotal();
  
/*for Person 5 Calculate total bill*/
System.out.print("Person 5");
/*set value of originalPrice*/
calc.originalPrice=7;
/*call findTotal method*/
calc.findTotal();
  
/*for Person 6 Calculate total bill*/
System.out.print("Person 6");
/*set value of originalPrice*/
calc.originalPrice=15;
/*call findTotal method*/
calc.findTotal();
  
/*for Person 7 Calculate total bill*/
System.out.print("Person 7");
