    Default ArrayList value to another ArrayList

    Hello, Is there a way to insert one value of an araryList into another ArrayList?
    One arraylist will be printed, the user should chose what value he wants to be inserted into another arraylist (using index numbers).

    ex. Arraylist
    Index 0 | Name: ... Lastname: ... City: ...
    Index 1 | Name: ... Lastname: ... City: ...
    Index 2 | Name: ... Lastname: ... City: ...

    the user choses the value that is in index 1, that name, lastname and city should be inserted into anoter arraylist, thoughts?

    Is there a way to insert one value of an araryList into another ArrayList?
    Yes. Look at the API doc for the ArrayList class. There are methods for getting a value from an arraylist and methods for adding that value to another arraylist.
    If you don't understand my answer, don't ignore it, ask a question.

    Are you using parallel ArrayLists to store/track data? If so, stop it.

    Store the data in the instance of a class, appropriately named. Since what you posted looks like an address, I'll call the class Address. If you need to collect a number of Address instances based on user selection, put the whole instance into a collection, maybe an ArrayList<Address>. Then, to print the collected instances, iterate the collection and print each part of the instance as needed or using the Address class' toString() method.

    If I've missed the mark, provide more details about what you're doing.
