java - How do I import images using ImageIcon? -

-

here's code, , i've got 2 problems evidently:

package test;  import javax.swing.imageicon; import javax.swing.jpanel; import java.awt.component;  public class { public static void main(string[] args) {     imageicon icon = new imageicon("src/icon.png",("what great image"));      jpanel window = new jpanel();     window.setlocation(100,100);     window.setsize(300, 500);     window.setvisible(true);  }

so don't know why jpanel won't reveal itself, , importing image right? i've created icon , placed in src folder. if i'm not importing right, how import then? question applies graphics swing since i'm interested in learning soon.

so don't know why jpanel won't reveal itself

you've not added can displayed. jpanel plain container allow add other components onto it.

you need kind of window display container, example...

jpanel window = new jpanel();  jframe frame = new jframe("testing"); frame.setdefaultcloseoperation(jframe.exit_on_close); frame.setlayout(new borderlayout()); frame.add(window); frame.setsize(200, 200); frame.setlocationrelativeto(null); frame.setvisible(true);

have read through how make frames (main windows) more details

i've created icon , placed in src folder. if i'm not importing right, how import then?

that's complicated question, because you've added image src directory, changes context of how image can loaded. essentially, becomes embedded resource.

so instead of using...

 imageicon icon = new imageicon("src/icon.png",("what great image"));

you need use more like...

 imageicon icon = new imageicon(something.getclass().getresource("icon.png"),("what great image"));

instead

you may find reading through how use labels, creating gui jfc/swing, initial threads, laying out components within container, reading/loading image helpful

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
