Convert feet to inches

I'm trying to make a program that converts inches to feet, and returns the number of feet and the number of leftover inches if any. I tried this:

public class Convertor
{
/**
 * Fields
 */
    private int inches;
    private int feet;
    private int yards;
    private int leftoverInches;

    /**
     * Constructor for objects of class Convertor
     */
    public Convertor()
    {
        inches=0;
        feet=0;
        yards=0;
        leftoverInches=0;
    }

    /**
     * Mutator method to convert inches to feet
     */
    public void convertValuesInchtoFeet(int anyInches)
    {
        inches=anyInches;
        feet=(anyInches * 0.083);
        leftoverInches= inches%feet;
        System.out.println(inches+" inches = " +feet+" feet.");
        System.out.println("There are " +leftoverinches +"  leftover inches");

    }

Doesn't work.

Someone help me on this, please! Thank you.

The primary reason your code doesn't work is because you're doing

leftoverInches = inches%feet;

Suppose you gave it 13 inches. You would have feet = 1 (13 * 0.083 rounded down), and inches = 13 % 1 = 0. What you mean to do was

leftoverInches = inches%12;

With 13, 13%12 = 1, which is indeed the number of leftover inches.

A smaller but still important error is that you multiply by 0.083, which is NOT 1/12, and will give you serious inaccuracies. For example, if you enter 1,000,000 inches, you will get

1000000 * 0.083 = 83000 feet

But

1000000 / 12 = 83333 feet rounded down

So you would be 333 feet off.

try this:

public void convertValuesInchtoFeet(int anyInches)
    {
        inches = anyInches;
        feet = Math.floor(inches/12);
               //if int than no need for the Math.floor()
        leftoverInches = inches%12;
        System.out.println(inches + " inches = " + feet + " feet.");
        System.out.println("There are " + leftoverInches + " leftover inches");

    }

int inches = 34;
int feet = inches / 12;
int leftover = inches % 12;
System.out.println(feet + " feet and " + leftover + " inches");
