Trying to Update Values of JThermometer and JSliders Dynamically in a for loop

I am new in java and trying to create a dashboard where I have N number of sensors and now i wants to show values of Humidity and temperature of each sensor in a separate panels . So firstly i have created N number of panels containing a JSlider and JThermometer for Humidity and temperature each. Now in a loop it reads the lines of outputs from arduino and i am trying to provide that values to that thermometers and sliders .
But i am not able to differentiate that output for which panel it is goin to set . even when i tried to set values to them it is not working at all.
Kindly give any idea how can i implement.
Thank you for help.

JButton update label

As in my last question, I declare that I'm very new to coding and Java is my only current language.
I'm building my first entirely independent project in eclipse, using a lot of Java imports.
It is a POS till system, it has 24 menu item buttons which are labelled by taking a string that holds null value to begin with.
I have an admin panel and from this panel I can update the title and price associated with the menu item button.
When I click "set" button relating to that particular menu item button, the string and double for item name and price update properly but title printed on JButton does not change.
What am I doing wrong/missing please?
Code follows:
public class Background implements ActionListener {
double menitprice1 = 0.0;
double menitprice2 = 0.0;
double menitprice3 = 0.0;
double menitprice4 = 0.0;

double menitprice7 = 0.0;
double menitprice8 = 0.0;

You could just create a String and then pass the value from that String into your action listener. Please find underneath a local String (should be an Instance, but for testing I have made a local one). And then I have passed it to the button.
if (source == menItSet1){
String text = setItem1.getText();
menitprice1 = Double.parseDouble(setPrice1.getText());
menuItem1.setText(text + " " + menitprice1);

How to append a scrollbar for the window?

How to append a scroll pane for my window?

Never add components directly to a scroll pane.
l1.setBounds(10,70,100,50);
Don't use setBounds(...). It is the job of the layout manager to set the size/location of the component.
The basic logic would be:
JPanel panel = new JPanel(); // set your layout manager for the panel.
panel.add( someComponent );
panel.add( anotherComponent );
JScrollPane scrollPane = new JScrollPane( panel );
frame.add( scrollPane );
Read the Swing Tutorial for Swing basics. Every section in the tutorial has working examples. Maybe start with the section on How to Use Scroll Panes.

This works, but you'll need to layout the components better..

Notes:
As mentioned by #camickr, setting the bounds of the components won't work reliably. Java GUIs have to work on different OS', screen size, screen resolution etc. using different PLAFs in different locales. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or combinations of them along with layout padding and borders for white space.
Please try to solve programming errors before you've got to dozens of components! For simple testing of layouts with many components, just add dummy components in a loop. To put that another way: For better help sooner, post a Minimal, Complete, and Verifiable example or Short, Self Contained, Correct Example.
Safer to use logical font names that specific one, e.g. Algerian will only work on systems with that font installed!

Passing Parameters to the print method (JAVA)

I need some help with my code. What i need it to do is everytime a page is added to the Java Book different data needs to be on the page every time. I've tried it a number of different ways and i just can't work it out!
Here's my code:
dataBase data = new dataBase();
int userCountAmount = data.getAmountOfUsers();
Book bk = new Book();
PrinterJob PJ = PrinterJob.getPrinterJob();
String[] pupilName = new String[userCountAmount];
String[] parentsName = new String[userCountAmount];
int parCount = 0;
int pupCount = 0;
public void print2() {
System.out.println(pupilName.length);
System.out.println(parentsName.length);
System.out.println(userCountAmount);
String[] custData = processData(data.getAllCustomers());
PageFormat portrait = PJ.defaultPage();
int pupNameCount = 0;
int parNameCount = 0;
portrait.setOrientation(PageFormat.PORTRAIT);
for (int i = 0; i < userCountAmount; i++) {
pupilName[i] = custData[pupNameCount];
parentsName[i] = custData[parNameCount];
System.out.println(custData[pupNameCount] + " " + custData[parNameCount]);
pupNameCount = pupNameCount + 13;
parNameCount = parNameCount + 13;
bk.append(new IntroPage(), PJ.defaultPage());
parCount++;
pupCount++;
System.out.println(parCount+" " + pupCount);
}
// setWindow();

So basically, all i need to do is pass additional parameters to the print method, but this is impossible! It wouldn't implement the print class other wise!
I've tried substituting arrays and a lot more, i can't think of anything else!

You can't add arguments to the print() as it must implement the interface.
However you can add any number of arguments to the constructor, and these can be used in your method.
bk.append(new IntroPage(arg1, arg2, arg3), PJ.defaultPage());

You could add fields to the class IntroPage. Then when you create IntroPage pass appropriate arguments to initialize your fileds. And later, in print(), you can use the data from your fileds.

Add a focus listener to your length text field when it loses focus and the round tub is selected, compute and set the the width.
