Can't add scroll bar to JTextarea

Hello Everyone I am new to Java so I am sure I am doing something obviously wrong here but I just keep going in circles.
I am trying to add a scroll to a JTextarea. Here is what I have tried but it doesn't show up.
textarea1 = new JTextArea();
textarea1.setBounds(251,26,795,345);
textarea1.setBackground(new Color(255,255,255));
textarea1.setForeground(new Color(0,0,0));
textarea1.setEnabled(true);
textarea1.setFont(new Font("sansserif",0,12));
textarea1.setText("");
textarea1.setBorder(BorderFactory.createBevelBorder(1));
textarea1.setVisible(true);
JScrollPane ScrollPane1 = new JScrollPane(textarea1);
ScrollPane1.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
//adding components to contentPane panel
contentPane.add(browseFileOne);
contentPane.add(browseOutput);
contentPane.add(button1);
contentPane.add(button2);
contentPane.add(button4);
contentPane.add(fileOneText);
contentPane.add(fileTwoText);
contentPane.add(label1);
contentPane.add(label2);
contentPane.add(label3);
contentPane.add(outputTextFile);
contentPane.add(textarea1);

see working example:

Why after I added a JComboBox into one of the JPanels, all JPanels were not rendered

When the JComboBox, cmbox was not added to a JPanel, two panels, p1 & p2 could be rendered. You may comment out the combo box portion to see the result. But after I added the combo box into one of the panels, all panels were not rendered.
My code is like the following:
import java.awt.*;
import javax.swing.*;
public class TestCombo {
public static void main(String[] args) {
JFrame frame = new JFrame("康樂彩歌");
frame.setVisible(true);
frame.setBounds(0, 0, 1368, 500);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel p1 = new JPanel();
p1.setBackground(Color.CYAN);
JRadioButton rb1 = new JRadioButton("加簡譜", false);
rb1.setFont(new Font("新細明體", Font.PLAIN, 20));
JRadioButton rb2 = new JRadioButton("加人聲", false);
rb2.setFont(new Font("新細明體", Font.PLAIN, 20));
rb1.setBounds(450, 180, 50, 50);
rb2.setBounds(500, 180, 50, 50);
JButton btPlay = new JButton("PLAY");
btPlay.setFont(new Font(Font.DIALOG_INPUT, Font.BOLD, 25));
btPlay.setBounds(100, 20, 100, 20);//x axis, y axis, width, height
JButton btStop = new JButton("STOP");
btStop.setFont(new Font(Font.DIALOG_INPUT, Font.BOLD, 25));
btStop.setBounds(140, 20, 100, 20);//x axis, y axis, width, height
//p1.add(cmbox);
p1.add(rb1);
p1.add(rb2);
p1.add(btPlay);
p1.add(btStop);
p1.setBorder(BorderFactory.createLineBorder(Color.black));
JPanel p2 = new JPanel();
p2.setBackground(Color.PINK);
p2.setBorder(BorderFactory.createLineBorder(Color.red));
JComboBox cmbox = new JComboBox(); //The JComboBox to be added to a JPanel
cmbox.setFont(new Font("新細明體", Font.PLAIN, 20));
cmbox.addItem("紫竹調");
cmbox.addItem("走一同去郊遊");
cmbox.addItem("大野狼");
cmbox.addItem("歸來吧蘇連多");
cmbox.addItem("追尋");
cmbox.addItem("三輪車");
cmbox.addItem("我家門前有小河");
cmbox.addItem("漁家樂");
cmbox.addItem("嚕啦啦");
cmbox.addItem("踏雪尋梅");
p2.add(cmbox);
frame.add(p1, BorderLayout.PAGE_START);
frame.add(p2, BorderLayout.CENTER);
}
}

Implementing the changes as detailed below the code, solves the problem.
import java.awt.*;
import javax.swing.*;
public class TestCombo {
public static void main(String[] args) {
JFrame frame = new JFrame("康樂彩歌");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel p1 = new JPanel();
p1.setBackground(Color.CYAN);
JRadioButton rb1 = new JRadioButton("加簡譜", false);
rb1.setFont(new Font("新細明體", Font.PLAIN, 20));
JRadioButton rb2 = new JRadioButton("加人聲", false);
rb2.setFont(new Font("新細明體", Font.PLAIN, 20));
JButton btPlay = new JButton("PLAY");
btPlay.setFont(new Font(Font.DIALOG_INPUT, Font.BOLD, 25));
JButton btStop = new JButton("STOP");
btStop.setFont(new Font(Font.DIALOG_INPUT, Font.BOLD, 25));
p1.add(rb1);
p1.add(rb2);
p1.add(btPlay);
p1.add(btStop);
p1.setBorder(BorderFactory.createLineBorder(Color.black));
JPanel p2 = new JPanel();
p2.setBackground(Color.PINK);
p2.setBorder(BorderFactory.createLineBorder(Color.red));
JComboBox cmbox = new JComboBox(); //The JComboBox to be added to a JPanel
cmbox.setFont(new Font("新細明體", Font.PLAIN, 20));
cmbox.addItem("紫竹調");
cmbox.addItem("走一同去郊遊");
cmbox.addItem("大野狼");
cmbox.addItem("歸來吧蘇連多");
cmbox.addItem("追尋");
cmbox.addItem("三輪車");
cmbox.addItem("我家門前有小河");
cmbox.addItem("漁家樂");
cmbox.addItem("嚕啦啦");
cmbox.addItem("踏雪尋梅");
p2.add(cmbox);
frame.add(p1, BorderLayout.PAGE_START);
frame.add(p2, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
}
}
btPlay.setBounds(100, 20, 100, 20); Do not set the bounds of components. Let the layouts (padding and borders) do their job.
frame.setBounds(0, 0, 1368, 500); That's just a guess, and if it's the right guess on one OS, it will be the wrong guess on others. Instead pack() the window after components are added.
Sidebar: GUIs should be started on the EDT. (Not implemented above: 'batteries not included'.)

Why JComponents does not appear in the frame?

I'm pretty new to java. And i can't get this to work... I'm trying to add components using this code:
public class Board
{
public static void main(String[] args) {
JFrame window = new JFrame("Tellraw Generator");
window.setVisible(true);
window.setSize(400, 600);
window.setResizable(false);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
JLabel label = new JLabel();
panel.setLayout(null);
window.add(panel);
//"Generate" Button
JButton button1 = new JButton("Generate");
button1.setBounds(262, 485, 100, 37);
panel.add(button1);
//"Add Text" Button
JButton button2 = new JButton("Add Text");
button2.setBounds(51, 337, 88, 33);
panel.add(button2);
//Title
JLabel txt1 = new JLabel("Tellraw Generator");
txt1.setFont(new Font("Minecrafter Alt Regular", Font.BOLD, 29));
txt1.setBounds(61, 18, 278, 30);
panel.add(txt1);
}
}
But when i'm trying to do it, the components aren't showing up on the screen.
So are there someone who can tell me why it isn't working/Showing up and how i can add it in ?
Thanks

You mean that JLabel and JButton don't appear? right ? not JTextField because there is no JTextField in the code
Anyway just add this line of code to the end:
window.add(panel);
Here you are adding the JPanel that contains all the JComponents to the JFrame

and always: have the setVisible(true) call as last call. Everything that you add to the window/frame must be done before the setVisible call

This is how to declare a JTextField
final JTextField variableName = new JTextField(size);
This is how you get the text from JTextField
variableName.getText()
Hope that helps.

Try this:
public class Board
{
public static void main(String[] args) {
JFrame window = new JFrame("Tellraw Generator");
window.setVisible(true);
window.setSize(400, 600);
window.setResizable(false);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
JLabel label = new JLabel();
panel.setLayout(null);
window.add(panel);
//"Generate" Button
JButton button1 = new JButton("Generate");
button1.setBounds(262, 485, 100, 37);
panel.add(button1);
//"Add Text" Button
JButton button2 = new JButton("Add Text");
button2.setBounds(51, 337, 88, 33);
panel.add(button2);
//Title
JTextField txt1 = new JTextField ();
txt1.setFont(new Font("Minecrafter Alt Regular", Font.BOLD, 29));
txt1.setBounds(61, 18, 278, 30);
panel.add(txt1);
}
}

RE-enable a button after closing a frame java

so im making a program for my project.
and when i clicked a button it must open anohter frame and make the button unclickable. and when you closed the popup frame the button must re enable. so this is

Any Suggestions about my coding is accepted. Sorry Still learning about Java :)

and when i clicked a button it must open anohter frame
You should NOT be creating another JFrame.
Instead you should be creating a modal JDialog. The dialog will not allow you to click on the frame until the dialog is closed.
Any Suggestions about my coding is accepted
Follow Java naming conventions. Variable names should NOT start with an upper case character. Sometimes you follow this guideline and sometimes you don't. Be consistent!
Don't use setBounds(...). Swing was designed to be used with layout managers!

First, please read Java naming conventions.
You need to pass the reference of MainMenu to PersonalInfo in order to achieve what you need, here:
button1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a){
PersonalInfo objPI = new PersonalInfo(this);
objPI.menu1();
button1.setEnabled(false);
}
});
And you need to add a constructor to PersonalInfo:
private MainMenu m;
public PersonalInfo(MainMenu m) {
this.m = m;
}
Add a public method to MainMenu:
public void enableMyButton() {
button1.setEnabled(true);
}
Now you can add an event listener to PersonalInfo to enable the button of the MainMenu frame:
frame1.addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
this.m.enableMyButton();
}
});

JTextField and JLabel not appearing

My JLabel and JTextField are not appearing overtop the image and I'm not sure why. I've put the image on a JLabel and setOpaque(false) but no luck. Any advice? Thanks for the help in advance.
private JTextField tf;
private JLabel jl2;
private JLabel jl3;
public void window() {
ImageIcon ic = new ImageIcon("hangman.png");
JFrame gameFrame = new JFrame();
JPanel jp = new JPanel();
jp.setOpaque(false); //!!
jp.setBorder(BorderFactory.createTitledBorder(""));
JLabel img = new JLabel(ic, JLabel.CENTER);
img.setOpaque(false);
JLabel jl = new JLabel("Enter a Letter:");
jl.setFont(new Font("Rockwell", Font.PLAIN, 20));
tf = new JTextField(1);
jl2 = new JLabel("Letters Used: ");
jl3 = new JLabel();//blank spaces
tf.setFont(new Font("Rockwell", Font.PLAIN, 20));
jl2.setFont(new Font("Rockwell", Font.PLAIN, 20));
jp.add(jl);
jp.add(tf);
jp.add(jl2);
jp.add(jl3);
gameFrame.add(img);
img.add(jp);
gameFrame.setTitle("Hangman");
gameFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
gameFrame.setIconImage(
new ImageIcon("Hangman-Game-grey.png").getImage());
gameFrame.setResizable(false);
gameFrame.pack();
gameFrame.setLocationRelativeTo(null);
gameFrame.setVisible(true);

A JLabel doesn't use a layout manager by default so components added to the label will not be painted.
Try setting the layout manager. Maybe:
img.setLayout( new BorderLayout() );
or choose a layout that meets your requirements.

You should add image, label and textfield objecs to panel, respectively. Then, you should add that panel to your frame. Also, put gameFrame.add(img); code before calling jp.add() methods. I don't know, if this is what you want but from what you try to do, I can say below code should work:
public void window()
{
ImageIcon ic = new ImageIcon("hangman.png");
JFrame gameFrame = new JFrame();
JPanel jp = new JPanel();
jp.setOpaque(false); // !!
jp.setBorder(BorderFactory.createTitledBorder(""));
JLabel img = new JLabel(ic, JLabel.CENTER);
img.setOpaque(false);
JLabel jl = new JLabel("Enter a Letter:");
jl.setFont(new Font("Rockwell", Font.PLAIN, 20));
tf = new JTextField(1);
jl2 = new JLabel("Letters Used: ");
jl3 = new JLabel();// blank spaces
tf.setFont(new Font("Rockwell", Font.PLAIN, 20));
jl2.setFont(new Font("Rockwell", Font.PLAIN, 20));
jp.add(img);
jp.add(jl);
jp.add(tf);
jp.add(jl2);
jp.add(jl3);
gameFrame.add(jp);
gameFrame.setTitle("Hangman");
gameFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
gameFrame.setIconImage(new ImageIcon("1.jpg").getImage());
gameFrame.setResizable(false);
gameFrame.pack();
gameFrame.setLocationRelativeTo(null);
gameFrame.setVisible(true);
}
