You need to input quarters, dimes etc as integers, not Strings. Try this:

import java.util.Scanner;

public class CoinCounter {

public static void main(String[] args) {

Scanner console = new Scanner(System.in);

double total = 0.0; // in dollars

int quarters, dimes, nickels, pennies;



System.out.println("Please enter the amount of quarters you have.");

quarters = console.nextInt();

System.out.println("Please enter the amount of dimes you have.");

dimes = console.nextInt();

System.out.println("Please enter the amount of nickels you have.");

nickels = console.nextInt();

System.out.println("Please enter the amount of Pennies you have");

pennies = console.nextInt();



total = 0.25*quarters + 0.1*dimes + 0.05*nickels + 0.01*pennies;

System.out.println("Total = $"+total);

}

}

this is supposed to be a program that takes a number input from a user in the terms of coin currency then add it up and output the amount of money they have.

i can get it to take the input from the console but i cant get it to multiply the input by the related amount a coins worth. such as someone inputs 5 for the quarters i cant multiple that 5 by .25

import java.util.Scanner;

public class CoinCounter {

public static void main(String[] args) {





Scanner console = new Scanner(System.in);



System.out.println("Please enter the amount of quarters you have.");

String value = console.nextLine();



System.out.println("Please enter the amount of dimes you have.");

String value2 = console.nextLine();



System.out.println("Please enter the amount of nickels you have.");

String value3 = console.nextLine();



System.out.println("Please enter the amount of Pennies you have");

String value4 = console.nextLine();
