Search an arraylist by the contents of a JTextField - arraylist.contains(jtextfield)?

Call 'getText' on the JTextField to get the string that they've entered. You'll basically do something like the following.

Currently, I'm trying to write a system, which is focused around inputting data into lists and arraylists, and implementing search and sort functionality. Currently on my system, I have: A class to store data An arraylist class which gets data from an object within the data storage class. And finally, a swing GUI class, which contains a JList which displays the Arraylist.

What i'm trying to do is search through the arraylist with a JButton actionlistener, and then output the results on the search to the JList. The JButton would take the contents of a JTextField, and check if the string is present in the ArrayList. My question first of all is, how would I go about creating a search function in the arraylist class, and call the contents of a JTextField in a seperate class?

Secondly, would I need to convert the jtextfield to a string before I could call a . Contains method on the arraylist? And thirdly, once the search function is implemented, how would I go about selecting a record from the arraylist if the text searched for is present Here is my Data storage class: http://pastebin.com/hwyD8r1j My arraylist class: http://pastebin.com/d3ftLsJb I'm not expecting you guys to write it for me, although that would be nice, haha.

But any pointers or insight on how I could go about implementing this functionality into my arraylist would be appreciated, Oh and if you need me to post my GUI class, just ask. Java search sorting arraylist jlist link|improve this question asked Dec 4 '11 at 19:06user1080390386 67% accept rate.

Call 'getText' on the JTextField to get the string that they've entered. You'll basically do something like the following. // Somehow you've initialized your array list List data = ...; // within your action listener - invoked when the button is clicked.

You'll need to // make sure the textField is "final" String selected = textfield.getText(); // Linear search through your strings for one matching your text for (String datum : data) { if (selected. Contains(datum)) { // do whatever you want here; you found a match } }.

– user1080390 Dec 4 '11 at 19:21 Look into model view controller pattern - will help you decide where code should reside. IMO you probably don't need a custom arraylist class. What are you adding to it?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
