Introduction to JFrame in Java. JFrame is a java class that is extended by Frame class of Java. JFrame is treated as the main window. In JFrame different elements such as labels, text fields, buttons can be added. These elements on JFrame create Graphical User Interface. JFrame is also known as Swing top-level container.
In this video, we create our first window using Java Swing and a JFrame. The code from this video is below: import javax.swing.JFrameJFrame myFrame = new JF
Write main method and inside the main method create an object of the JFrame class. This is because you will have to import JFrame from the Java Swing library. It's not hard; just add this line to the very top of your code: If you're using Eclipse, you can simply hit ctrl+shift+o to fix all of your imports automatically. This is handy so that you don't have to memorize how to import individual parts. Otherwise, newly created JFrames will have their Window decorations provided by the current window manager. You can get the same effect on a single JFrame by doing the following: JFrame frame = new JFrame(); frame.setUndecorated(true); frame.getRootPane().setWindowDecorationStyle(JRootPane.FRAME); import java.awt.Color; import java.awt.BorderLayout; import java.awt.GridLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.ButtonGroup; import javax.swing.JButton; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JRadioButton; public class Director extends JFrame implements CollisionListener { private BrickWall wall; private JLabel gameTitle, gameScore import javax.swing.JFrame; import javax.swing.JLabel; public class StoryFrame extends JFrame { public StoryFrame() { setTitle("見張ってしながら"); setSize(400,500); setDefaultCloseOperation(EXIT_ON_CLOSE); setLocationRelativeTo(null); setVisible(true); } public void displayText() { JLabel Text = new JLabel(); add(Text); // I feel I need to add a lot more here to connect the two classes } } import java.util.Scanner; import java.io.File; import java.io.IOException; class ShowIntro We have imported javax.swing.JFrame to be able to use the JFrame component. Inside our constructor is the calling of different methods in the creation of a JFrame: frame = new JFrame () – Create an instance of JFrame and store it to the variable frame.
