    Question How to create Choices in Java?

    Can you please tell me how to create multiple Choices in one Panel?
    I need to create a program that will choose a number in these choices then it will display the words at the bottom.

    E.g. "Two Thousand Fourteen"
    "Three Thousand"
    "Two Thousand"

    Please help me.

    Supposing in Swing, a "choice" can be created with the JComboBox component. In order to have more JComboBox components in a single JPanel, you need a specific layout manager in the JPanel or you can use "absolute" positioning.

    Here's a link to the Swing tutorials. Your question is not specific enough to determine what help you need.

    I'm sorry. I just need to know how to create choices like these. 4 choices. The first one is from 0-3, the second up to the fourth one is 0-9. When you choose a number, it will display the corresponding words instead of numbers.

    I don't know how to create these choices using the For Loop. Please help me.

    I'm not sure of the purpose of the for loop. Perhaps you could explain that part, but before then, read the Swing tutorial on using the JComboBox. There's not much more we can do for you until you understand Swing basics and make an attempt to code that part.

    If the number of choice components is known/fixed and if the values are also known/fixed, there's no really need to use "loops".

    Here is a simple example:

    Integer[] evenValues = { 2, 4, 6, 8 };     // note: autoboxing since Java 5
    JComboBox evenNumbersCombo = new JComboBox(evenValues);

    If you use JComboBox as I have described above, you have an Integer object as the "selected" value (not a primitive int).
    How to generate a number in letters is another story. Every language, english, italian, etc... has its specific rules to form "literal numbers". And in general there are also many special/corner cases. You have to known these rules.
