Question

How can I create a data Model class ? , The data will be stored in an ArrayList. The array will store 4 pieces of data [ID,NAME,AGE,Gender]. the data will be sent to this class from JTextField.

I’m also willing to use vector instead of ArrayList.

I’ve tried looking for example but I can’t seem to find any that I can use for reference.
Thank you.

Use a custom Class and implements Comparable interface write your sorting logic. Insert all data to List. sort it by Collections.sort(list);

class User implements Comparable<User>{
    private String name;
    private long id;
    private Date age;
    private boolean gender;
    @Override
    public int compareTo(User user1) {
        return this.age.compareTo(user1.age);
    }
} 

List<User> users = new ArrayList();
users.add(user);
...
Collections.sort(list);
