Java Gui cannot scroll through scrollPane

I am creating a Gui in java and I wanted to have a list of selectable checkboxes in a smaller pane that allows you to scroll through it. I have it set up but I may have messed up somewhere that it does not allow me to scroll, any help is appreciated.
GUI:
Code:

frame.getContentPane().add(panel_1);

I've tried to do it myself
btnManga.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
manga mangaWindow = new manga();
mangaWindow.setVisible(true);
}
});
However, this displays an empty window when I click on it.

In your main method in manga you show the window correctly.
`mangaWindow.frmAcheterDesLivres.setVisible(true);`
In your action listener you call mangaWindow.setVisible(true); but mangaWindow has no components added to it. You need to includ the reference to the JFrame.
btnManga.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
manga mangaWindow = new manga();
mangaWindow.frmAcheterDesLivres.setVisible(true);
}
});
You should delete the extends JFrame to avoid this confusion. You should also use JDialog extra windows.

if you are using netbeans, create a button, then generate actionperformed on that button, then you can follow the following
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
manga mangaWindow = new manga();
mangaWindow.setVisible(true);
}

Did you try adding mangaWindow.setSize before setVisible?
Edit: also you shouldn't have two different main methods in your application (technically there is nothing bad on it but it can be confusing because only one of them will be used when launching the application)

Why does this program's interface disappear to the right?

I'm working on a group project with my friends for a school assignment. Unfortunately, one of my group members made this program which was much worse before (I tried to fix most of the main issues). Only problem now is, the program doesn't load all of the text on the right, instead leaving ellipses (...).
I've tried modifying and removing setBounds, setSize, and contentPane, yet all those proved ineffective. I'm fairly new to Java all round, so please do go easy on my inexperience.

Instead of "WE DO nothin..." and "Wel..." (at the top right), it should display "WE DO nothing at ALL!" (Also, do let me know if the code doesn't work.)

can not refer a value to a radiobutton

i write a convert temperature code using radiobutton, but when i use actionListener to print the value to a label, it show "Cannot refer to the non-final local variable valueto defined in an enclosing scope"
can some one show me the problem and how to fix it? (also sorry for my English)
the Radiobutton
JRadioButton Cbutton = new JRadioButton("Celsius");
Fbutton.setFont(new Font("Tahoma", Font.PLAIN, 12));
Fbutton.setBounds(10, 40, 109, 23);
contentPane.add(Cbutton);
JRadioButton Fbutton2 = new JRadioButton("Fahrenheit");
Fbutton2.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
label.setText(String.valueOf(valueto));
}
});
i use this to convert
if(Fbutton.isSelected()&&Cbutton2.isSelected()){
value=F;
valueto=(F-32)/1.8;
}else if(Fbutton.isSelected()&&Kbutton2.isSelected()){
value=F;
valueto=(F+459.67)*5/9;
}else if(Cbutton.isSelected()&&Fbutton2.isSelected()){
value=C;
valueto=C*1.8+32;
}else if(Cbutton.isSelected()&&Kbutton2.isSelected()){
value=C;
valueto=C+273.15;
}else if(Kbutton.isSelected()&&Cbutton2.isSelected()){
value=K;
valueto=K-273.15;
}else if(Kbutton.isSelected()&&Fbutton2.isSelected()){
value=K;
valueto=K*9.5-459.67;
}
Edit : i declare valueto at the bottom of the class
double value = 0;
double valueto = 0;
double F = 0, C = 0, K = 0;
it ask me to add final to "double valueto", but when i add it the valueto in "if" become error

Java Swing GUI Invisible

basically I have a very simple GUI, but for some reason when I run the code the JButtons only appear when I mouse over them, and the JTextField only appear if I click on them. How do I fix this so that they are visible when the program runs? Thanks.
Here is my code:
//JFrame + settings
JFrame frmFormSubmission = new JFrame();
frmFormSubmission.setSize(new Dimension(350, 165));
frmFormSubmission.setTitle("Form Submission - Client");
frmFormSubmission.setLocationRelativeTo(null);
frmFormSubmission.setVisible(true);
frmFormSubmission.setResizable(false);
frmFormSubmission.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//JPanel
JPanel panel = new JPanel();
frmFormSubmission.getContentPane().add(panel, BorderLayout.CENTER);
panel.setLayout(null);
//JLabels
//Name
JLabel lblName = new JLabel("Name:");
lblName.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblName.setBounds(46, 12, 40, 14);
panel.add(lblName);
//Address
JLabel lblAddress = new JLabel("Address:");
lblAddress.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblAddress.setBounds(33, 37, 53, 14);
panel.add(lblAddress);
//Phone
JLabel lblPhone = new JLabel("Phone #:");
lblPhone.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblPhone.setBounds(28, 62, 58, 14);
panel.add(lblPhone);
//Email
JLabel lblEmail = new JLabel("Email:");
lblEmail.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblEmail.setBounds(46, 87, 36, 14);
panel.add(lblEmail);
//JTextFields
//Name
nameField = new JTextField();
nameField.setBounds(93, 11, 137, 20);
panel.add(nameField);
nameField.setColumns(10);
//Address
addressField = new JTextField();
addressField.setColumns(10);
addressField.setBounds(93, 36, 137, 20);
panel.add(addressField);
//Phone
phoneField = new JTextField();
phoneField.setColumns(10);
phoneField.setBounds(93, 61, 137, 20);
panel.add(phoneField);
//Email
emailField = new JTextField();
emailField.setColumns(10);
emailField.setBounds(93, 86, 137, 20);
panel.add(emailField);
//JButtons
//Submit
JButton btnSubmit = new JButton("Submit");
btnSubmit.setBounds(240, 10, 89, 23);
panel.add(btnSubmit);
//Cancel
JButton btnCancel = new JButton("Cancel");
btnCancel.setBounds(240, 44, 89, 23);
panel.add(btnCancel);
//Flush
JButton btnFlush = new JButton("Flush");
btnFlush.setBounds(240, 76, 89, 23);
panel.add(btnFlush);
//Checkbox
JCheckBox chckbxPromotions = new JCheckBox("Email me with new and promotions!");
chckbxPromotions.setBounds(25, 108, 205, 23);
panel.add(chckbxPromotions);
Any help is very much appreciated!

Call frmFormSubmission.setVisible(true); as the last thing you do. setVisible will layout your components so they can be properly drawn. If you add components without laying them out, then you'll have graphical issues.
For more information on what that means, check out the documentation on the validate method.

Also, try
frmFormSubmission.invalidate();
frmFormSubmission.validate();
frmFormSubmission.repaint();
If this still does not work, you can try this:
SwingUtilities.updateComponentTreeUI(frmFormSubmission);
