Java（如何在输出中添加小数）

Question

//我不能有任何双打，只有int。我得到了正确的结果，但是可以添加小数？而不是150，我想说1.50。感谢。

import java.util.Scanner;

public class coinsInJar
{
    public static void main(String[] args)
    {
        int quarters, dimes, nickels, pennies, totalValue, totalValue2; 
        Scanner scan = new Scanner(System.in);


        System.out.print ("Enter the number of quarters: "); 
        quarters = scan.nextInt();

        System.out.print ("Enter the number of dimes: ");
        dimes = scan.nextInt();

        System.out.print ("Enter the number of nickels: "); 
        nickels = scan.nextInt();

        System.out.print ("Enter the number of pennies: "); 
        pennies = scan.nextInt();

        totalValue = (quarters * 25) + (dimes * 10) + (nickels * 5) + (pennies * 1);

        System.out.print ("Total value: $" + totalValue);

    }
}

打印整数值，然后打印点，然后打印其余部分：

System.out.print ("Total value: $" + totalValue/100 + "." + totalValue%100);
