Problem description:

When learning to use Java's GUI, insert a picture but do not display it

The code is as follows:

Public abstract class AbstractMainFrame extends JFrame {private JLabel titleLabel = new JLabel (new ImageIcon ("fruit.jpg")); private JButton btn = new JButton ("enter the system"); private void init () {this.setTitle ("welcome to the fruit supermarket"); this.setSize (600600); this.setResizable (false); this.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE) } private void addComponent () {this.add (this.titleLabel, BorderLayout.NORTH); JPanel btnPanel = new JPanel (); this.add (btnPanel,BorderLayout.CENTER); btnPanel.setLayout (null); btn.setBounds (200lr20, 20050); btnPanel.add (btn);} public AbstractMainFrame () {this.init (); this.addComponent ();}}

Cause analysis and solution: pay attention to the storage path of the picture

The fruit.jpg is stored in the wrong location, causing the system to fail to find it.

It turns out that I put the pictures in the src folder.

Should be stored in the Project project folder, at the same level as the src folder. ┑ (traditional Chinese medicine) ┍
