Java programmers look inside!

[Slimfast]

Hi, for the programming course at school I need to figure out how to display a jpg image in java in an application, not applet, at the end of a game that I wrote. Can anyone help me out? thanks!

[mprielozny]

not applet,

can you at least use swing?

[Slimfast]

i'm ******** at swing....(I can only do really basic level programming) but can you post some demo code? the stuff i find on google won't compile..maybe i'm doing something wrong. I'm using ConTEXT and compiling stuff through there.

especially look for something like

jPanel1 = new JPanel();
jPanel1.setBorder(new javax.swing.border.EtchedBorder());
jPanel1.setBounds(408, 164, 160, 170);
getContentPane().add(jPanel1);

jLabel1 = new JLabel(new ImageIcon("resources/legend.png"));//new ImageIcon("resources/icon_thing.gif").getImage());
jLabel1.setBounds(0, 0, 200, 200);
jLabel1.setVisible(true);
jPanel1.add(jLabel1);

[Slimfast]

I need all that to display one lousy picture? yowch

[mprielozny]

definately not ;)

tihs is enough

jPanel1 = new JPanel();
jPanel1.setBorder(new javax.swing.border.EtchedBorder());
jPanel1.setBounds(408, 164, 160, 170);
getContentPane().add(jPanel1);

jLabel1 = new JLabel(new ImageIcon("resources/legend.png"));//new ImageIcon("resources/icon_thing.gif").getImage());
jLabel1.setBounds(0, 0, 200, 200);
jLabel1.setVisible(true);
jPanel1.add(jLabel1);

[chatbox]

Damn, that's still close to a dozen lines to display a pic!

[fwhc022883]

Damn, that's still close to a dozen lines to display a pic!

Some of those lines are just for visual enhancements such as the setBorder and the setBounds method. I just squeeze it into 4 lines.

[Slimfast]

i got it working! Thanks a lot guys!

[deep]

definately not ;)

jPanel1 = new JPanel();
jPanel1.setBorder(new javax.swing.border.EtchedBorder());
jPanel1.setBounds(408, 164, 160, 170);

jLabel1 = new JLabel(new ImageIcon("resources/legend.png"));//new ImageIcon("resources/icon_thing.gif").getImage());

jLabel1.setVisible(true);
jPanel1.add(jLabel1);

Java seems so efficient suddenly. :|

well you can go this

getContentPane().add(new JLabel(new ImageIcon("resources/legend.png")));


and i guess you never used any of the real programming languages like 10-15 years ago when displaying JPG took close to 2000 lines.

now they make it too easy for newbies they dont appriciate how easy they have it.

[temporalillusion]

do(whatImThinking);

Thats how java is. If you want to do this stuff with less code, choose a different language, that or find some java libraries that will make it easier.

Firstly,no, thank God for that! At this time in computing history, I don't even care about the 2000 lines from 10-15 years ago. It just doesn't contribute to the languages of today's computing.

Secondly, I do appreciate the fact that I don't have to write 2000 lines of code, but that doesn't stop me from not accecpting (or dislike) the 9 lines of code. i.e. Me appreciating something doesn't mean I can't request a further improvement. That's how technology improves over time, by people like us demanding more.

oh well.. it's easy to run on different OS..

Lol, haven't looked at Java since 1995?

Great to see decade old myths and generalizations are alive and well.

this is a typical reply of someone who has not done any research on it.

java is faster than gcc and definately anything microsoft comes up with.

the only faster compiler is Intel C optimized.

as we all know memory is cheap now and as memory will get faster the faster will Java get.
