    Default How to print to textarea? really no idea.

    Im pretty new to this programming so forgive me if i make any mistakes. Im making a little program with NetBeans, only now i have to add something which i really dont know how to do.

    I've made a little program with which you can calculate your interest. You have three jTextFields:

    1.Your starting amount of money.
    2.The percentage of interest you're dealing with.
    3.The amount of years you want to calculate.

    So further i have a jButton which contains the most of my code.

    double inputNumberInterest = Double.parseDouble(interest.getText());
        double inputNumberMoney = Double.parseDouble(money.getText());
        int inputNumberYears = Integer.parseInt(years.getText());
        DecimalFormat decimaal = new DecimalFormat("#,###.##");
     
        double result = inputNumberMoney * Math.pow(inputNumberInterest / 100 + 1,    inputNumberYears);
     
        this.reply.setText("" + decimaal.format(result);

    So this code prints the end result of the calculation. Now what my question is, I want to years in between to be printed also in a textArea. For example the user of this program enters 5, as years of interest. I want the 1st, 2nd, 3rd and 4th to be printed in a textArea. And the 5th year as it is now printed in a jTextField as i already have.

    Does anyone know how to do this?

    I hope to hear from you soon.

    Use append() to add multiple lines of text, one after the other, in a JTextArea.

    Now what my question is, I want to years in between to be printed also in a textArea. For example the user of this program enters 5, as years of interest. I want the 1st, 2nd, 3rd and 4th to be printed in a textArea. And the 5th year as it is now printed in a jTextField as i already have.
    Show an example of how you imagine what you've described should look. To include multiple items in a single String object, use the concatenation operator, '+', e.g. "this" + "that" = "thisthat".
