You said "You are attempting to load the image inside paintComponent(). This is not the place to do it."

Could you type out some code I could paste in to display the image? A bit over my head right now.

public void test(){ Graphics g = getGraphics(); g.drawImage("https://timedotcom.files.wordpress.com/2015/01/trump.jpg", 200, 200, SimpleGuiB.this); }

Not sure if I am doing the last parameter correctly, I am following other examples, but I am getting an error:

Multiple markers at this line
- Line breakpoint:SimpleGuiB [line: 23] - test()
- The method drawImage(Image, int, int, ImageObserver) in the type Graphics is not applicable for the arguments (String, int, int,
SimpleGuiB)

import javax.swing.*; import javax.swing.text.Utilities; import java.awt.Color; import java.awt.Graphics; import java.awt.Image; import java.awt.event.*; import java.net.MalformedURLException; import java.net.URL; import java.awt.*; public class SimpleGuiB extends JPanel implements ActionListener { JButton button; public static void main (String[] args) { SimpleGuiB gui = new SimpleGuiB(); gui.go(); } public void test(){ Graphics g = getGraphics(); g.drawImage("https://timedotcom.files.wordpress.com/2015/01/trump.jpg", 200, 200, SimpleGuiB.this); } public void go(){ URL test; try { test = new URL("https://timedotcom.files.wordpress.com/2015/01/trump.jpg"); Image image = new ImageIcon(test).getImage(); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } SimpleGuiB gui = new SimpleGuiB(); JFrame frame = new JFrame(); /* button = new JButton("It's Time to Make America Great Again."); button.setSize(50,50); button.addActionListener(this); frame.setTitle("Trump 2016"); frame.getContentPane().add(button); */ frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(970, 600); frame.add(gui); frame.setVisible(true); } /* public void paintComponent(Graphics g){ super.paintComponent(g); g.setColor(Color.red); g.drawRect(100, 150, 100, 100); g.drawOval(255, 255, 255, 255); g.setColor(Color.BLACK); g.drawLine(10, 10, 500, 500); g.setColor(Color.DARK_GRAY); } public void actionPerformed(ActionEvent event){ button.setVisible(false); } */ }

Ahh, I removed it from there. Would I create a custom method for it? I tried it in the go() method but it wont load there either. Any suggestions?

I did have some paintcode just didnt want to complicate and divert attention to it.

Oh, sorry forgot to mention.

Got it to get past the exception error with a new image link with two slashes "//" but the JFrame its supposed to display the image on is just blank.

Any ideas?

Full code:

public class SimpleGuiB extends JPanel implements ActionListener {
JButton button;

public static void main (String[] args) {
SimpleGuiB gui = new SimpleGuiB();
gui.go();
}

public void go(){
SimpleGuiB gui = new SimpleGuiB();
JFrame frame = new JFrame();

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(970, 600);
frame.setVisible(true);
frame.add(gui);
}

public void paintComponent(Graphics g){

URL test;
try {
test = new URL("https://timedotcom.files.wordpress.com/2015/01/trump.jpg");
Image image = new ImageIcon(test).getImage();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Ive been following my book on ImageIcons but decided to try out a URL:

URL test; try { test = new URL("http:/cdn.bgr.com/2015/06/usa-election-trump-6.jpg"); Image image = new ImageIcon(test).getImage(); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); }

Can anyone explain why this is not working or give me a tip on how I can?

Thank you.

Can someone explain what exactly is going on in this statement?

Sequencer sequencer = MidiSystem.getSequencer();

Am I thinking correctly about this statement? You are creating a reference variable called "sequencer" to the Sequencer Interface, yet its calling a method?

I am understanding of object creation and polymorphism such as: Sequencer sequencer = new Sequencer(); or Animal a = new lizard(); But here I am a bit confused to what is going on.
