Hey there!

I was doing the Mortgage Calculator and found out I had a very repetitive pattern on the CalculateMortgage class. Let me just show you:

```java
package me.oriol;

public class MortgageCalculator {

    private final Console console = new Console();

    public double calculateMortgage() {
        return console.principal
                * console.monthlyInterest * Math.pow(1 + console.monthlyInterest, console.numberOfPayments)
                / (Math.pow(1 + console.monthlyInterest, console.numberOfPayments) - 1);
    }

    private double calculateBalance(short numberOfPaymentsMade) {
        return console.principal
                * (Math.pow(1 + console.monthlyInterest, console.numberOfPayments)
                - Math.pow(1 + console.monthlyInterest, numberOfPaymentsMade))
                / (Math.pow(1 + console.monthlyInterest, console.numberOfPayments) - 1);
    }

    public double[] getRemainingBalances() {
        var balances = new double[console.numberOfPayments];
        for (short month = 1; month <= balances.length; month++)
            balances[month -1] = calculateBalance(month);
        return balances;
    }
}

```

As you can see, there’re lots of console. and the variable I want to use from the Console class. Is there a way to cut down on those (other than just setting 3 fields specifying each variable to a new name, that’s not what I’m looking for)?  
I’m looking for a clean solution which doesn’t need to use 3 fields in the CalculateMortgage class.

Edit: any other observation to clean the code/improve it or whatever is useful as well!

We can probably resolve this over in your original post ([Any flaws on my Mortgage Calculator?](https://forum.codewithmosh.com/t/any-flaws-on-my-mortgage-calculator/15844)), but basically it looks like your Console class is not the right place to be storing those values.
