Great channel, helped me with my grade 12 summative the whole way through!

Thank you very much for sharing this video, easy to understand.

[somerandomuser]

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
See the track
// See number labels




//Edit based on slider size



//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);

// Default is horizontal

// 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.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

Hi!
label.setText(“C “+slider.getValue());



Whatever position I set (Left, Right, Top etc..), the text doesn’t move after restart the program. Why??

[angelcastineira]

//is there a significant difference between this code:


@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());

}
});

[matheustavares]

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

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);





<<This is where magic happens>>



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());
}

}

}

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

[tingping]

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 :(
