[@somerandomuser8005]

Thanks for everything so far! Definitely will continue watching. This is like a game using the slider and a couple labels. (main method just has to have "new GetThere();" asides from the pre-generated stuff) import java.awt.*; import javax.swing.*; import javax.swing.event.*; import java.util.Random; public class GetThere implements ChangeListener{ //Game variables Random r = new Random(); //Edit Here int min = 0; // any number int max = 100; // must be greater than min int goal = r.nextInt(max-min)+min; int points; //GUI JFrame frame; JPanel panel; JLabel current; JLabel point; JLabel goalLabel; JSlider slider; GetThere(){ frame = new JFrame("Slider Demonstration"); panel = new JPanel(); current = new JLabel(); point = new JLabel(); goalLabel = new JLabel(); slider = new JSlider(min,max,(max+min)/2); // Low , High, Start slider.setPreferredSize(new Dimension(1000,200)); //size of the slider in the frame slider.setPaintTicks(true); // See ticks on the track slider.setPaintTrack(true); // See the track slider.setPaintLabels(true); // See number labels slider.setBackground(Color.black); panel.setBackground(Color.black); //Edit based on slider size slider.setMinorTickSpacing(5); slider.setMajorTickSpacing(25); //Fonts of ... slider.setFont(new Font("MV Boli",Font.BOLD,15)); //Slider numbers slider.setForeground(new Color(25,155,25)); // Text Color current.setFont(new Font("MV Boli",Font.BOLD,15)); //Current current.setForeground(new Color(25,155,25)); point.setFont(new Font("MV Boli",Font.BOLD,18)); //Point point.setForeground(new Color(35,175,35)); goalLabel.setFont(new Font("MV Boli",Font.BOLD,15)); //Goal goalLabel.setForeground(new Color(25,155,25)); //Default Texts current.setText("Current Pos: "+ slider.getValue()); point.setText("| Points: "+ points +" |"); goalLabel.setText("Goal: "+ goal); //slider.setOrientation(SwingConstants.VERTICAL); // Default is horizontal slider.addChangeListener(this); // when you move the thing /* * Only way I could keep things from shaking and having the labels under the slider * and all that stuff (high x-distance between things in FlowLayout). * A better way will prob show up */ panel.setLayout(new FlowLayout(FlowLayout.CENTER,1000,10)); //Add things to the panel panel.add(slider); panel.add(current); panel.add(point); panel.add(goalLabel); //Add things to the FRAME frame.add(panel); //Frame stuff frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(1250,750); //So frame isn't smol frame.setVisible(true); } @Override public void stateChanged(ChangeEvent e) { // TODO Auto-generated method stub //Format: Current Pos: 69 | Points: 1 | Goal: 420 //Updates Text current.setText("Current Pos: "+ slider.getValue()); point.setText(" | Points: "+ points +" | "); goalLabel.setText("Goal: "+ goal); if(slider.getValue() == goal) { goal = r.nextInt(max-min)+min; points ++; } } } //edit was for rearranging sentences

//is there a significant difference between this code: slider.addChangeListener(this); @Override public void stateChanged(ChangeEvent e) { label.setText("°C = "+ slider.getValue()); } // and this one?: slider.addChangeListener(new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { label.setText("°C = "+ slider.getValue()); } });

[@BroCodez]

I believe both would be fine. They perform the same task. The second one might be better for a larger program, because you're using an anonymous inner class. It's more efficient. I have a video on inner classes coming up in this playlist

[@angelcastineira2561]

@@BroCodez thanks!

[@lequangnghi194]

I'm wondering why my label is not underneath the slider but on the right side, can someone help me please?

[@Arthur-g5n8q]

Why use the stateChanged rather than the actionListener?

[@giahuypham1857]

[@uykerrykaberga]

thnx bruh

[@Soyosan22]

You forgot: frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

[@nehalayaaz9406]

thanks 😊

[@nawfalnjm5699]

thank you

[@matheustavares4597]

I rewrote the code i realized i don't need a panel to use JSlider, why did you use panel in this code? example: import javax.swing.JFrame; import javax.swing.JSlider; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; public class Main extends JFrame { JButton b; JPanel panel; JSlider slider; Main(){ b = new JButton(); b.setText("Click here"); b.addActionListener(new event()); slider = new JSlider(0,100); slider.setPaintTicks(true); slider.setMinorTickSpacing(10); slider.setPaintTrack(true); slider.setMajorTickSpacing(25); slider.setPaintLabels(true);// this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setLayout(new FlowLayout()); this.add(b); this.add(slider); this.pack(); this.setVisible(true); } public static void main(String[] args){ new Main(); } class event implements ActionListener{ @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub System.out.println("You have manipulated the temperature to " + slider.getValue()); } } }

[@michalj121]

Hi! label.setText(“C “+slider.getValue()); label.setVerticalTextPosition(JLabel.Top); label.setHorizontalTextPosition(JLabel.Left); Whatever position I set (Left,Right,Top etc..), the text doesn’t move after restart the program. Why??

[@sehejkumar9984]

change the left to LEFT and Top to TOP cuz it shld be capitalized

[@arpitchauhan5212]

how to increase and decrease the Value by taking input from the User?

[@jakubmrazek001]

You can do it with a scanner + method setValue(int value) Scanner scanner = new Scanner(System.in); JSlider slider = new JSlider(); int value = scanner.nextInt(); slider.setValue(value);

It's a great video , I like this . But , I don't know when we should use panel , label . I usually think frame can add everything we want :(
