Hi, i would like to ask about one problem that i tried to resolve in java. I have a lot of objects (textFields in this case) and i would like to read from them (calling method getText()) at the same time, or better explained, in one or few commands.
I have already tried adding them into the container but it didnt work. Maybe ihave done it wrong. Is there any method how to work with them as a group and calling their methods simultaneosly(in one or few command)? I thought, it could work using Java Message Service but i havent worked with it yet. Sending the message to all these objects that they have to do somethin.

What do you mean at the same time? What do you need to do exactly?

i need to have several objects(of the same type) in a group, so that i can work with them.
For example i have 4 textFields and i want to read from them. Now i have to do this

String s1 = jTextField1.getText();
String s2 = jTextField2.getText();
String s3 = jTextField3.getText();
String s4 = jTextField4.getText();

Because if i have 20 text fields its a little bit huge code :c-smile:

[eafkuor]

int SIZE=20;
JTextField [] fields = new JTextField[SIZE];
String [] strings = new String[SIZE];


for(int i=0;i<SIZE;i++)
    strings[i]=fields[i].getText();

Here you go ;)

I would suggest to add the objects into a collection class, and do the "work" with the collection class. I mean by adding some method to the collection class. This way it's easier to maintain and to improve.

Yes but he has to get rid of redundant code, and the only way to go are arrays.

Hi eafkuor,

My suggestion is for the real implementation. There is no problem with your code, however it's better use your code inside a collection class for the reasons I mentioned. :)
