[@pierotorchio1945]

how can I sort alphabetically items inside a combobox ? Thanks

[@MrLoser-ks2xn]

Thanks

[@PMe-my1td]

Hey Bro! Question for you!
How do you setSelectedItem(String_var_here) from another class calling the JcomboBox. It doesnt show the change on the GUI and the box is 'frozen'.

keep it on

How to store user’s selection in a variable

[@jaybartgis5148]

Oh never mind never mind I got it. For the actionPerformed method, you would then continue it with numerous if statements and say "if(animals.getSelectedIndex()==0 {sysout("German Sheppard")" i see now, i get it

[@AnthonyR007]

You should’ve replied this to your original comment lol

[@joaquingutierrez7296]

Can i change the color of scroll? How?

[@Artimer]

how much do you program every day?

[@BroCodez]

I mostly code exclusively for these videos almost daily, but I do have other projects I work on occasionally

[@jaybartgis5148]

4:25 so what if you want the getSelectedItem to show different text that corresponds to each string on the GUI? So let's say I want to click dog and I want the sysout to say "German Sheppard", how you do that?
Thanks for the reply and your free educational videos

[@AnthonyR007]

If statement, in the action listener, if the text is dog, output German shepard

[@jaybartgis5148]

@@AnthonyR007 so i did exactly that but now i have hundreds of if statements for every single dog breed and it looks totally all unprofessional and not "programmer like". I'm trying to make an array of dog breeds and just writing one if statements with the array number in the parameters

[@jaybartgis5148]

@@AnthonyR007 i can't quite get it to work because I'm not trained or a professional so i guess I'll just continue writing hundreds of if statements like a noob lol

[@AnthonyR007]

@@jaybartgis5148 you could use a switch case statement with the indexes?

[@AnthonyR007]

It’ll still be a lot of code, but it will be less resource intensive

Can I add a JComboBox on a JFrame with null Layout or a BorderLayout?

[@Michel-dx1bn]

Yes, in this video he used a border layout ( If you don't set a layout for a JFrame, it will use a BorderLayout by default )
Also it works for null layout but don't forget to set the bounds and pack the frame.

Hey.

[@miguelosvaldofloresdomingu8911]

Hi, guys. Can someone help me with one situation I noticed? When I use the setEditable method and type one item that isn't the first one it executes the action performed method twice. This doesn't happen when I type in the comboBox the first Item.
I'm goin' to let the code here in case anyone knows what is wrong here, and how can I make it work better.

Yo just wanna say that GOD loved the world so much he sent his only begotten
son Jesus to die a brutal death for us so that we can have eternal life
and we can all accept this amazing gift this by simply believing in him (Jesus) asking for the forgiveness of your sins
and forming a relationship with heavenly father.
