How can we compare two Strings and get duplicates values

I created a window with a button and 3 fields, 1st, 2nd field is the text, and in the 3rd field, it is necessary to write down words that are repeated in 1st & 2nd fields. How to make it?
JFrame frame = new JFrame("new Frame");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Label lbTextLabel = new Label("1:");
lbTextLabel.setBounds(50, 10, 120, 20);
Label lbTextLabel2 = new Label("2:");
lbTextLabel2.setBounds(50, 50, 120, 20);
Label lbTextLabel3 = new Label("3:");
lbTextLabel3.setBounds(50, 90, 120, 20);
JTextArea TextArea = new JTextArea("Welcome to javatpoint");
TextArea.setBounds(50,30, 120,20);
JTextArea TextArea2 = new JTextArea("Welcome to javatpoint 2");
TextArea2.setBounds(50,70, 127,20);
JTextArea TextArea3 = new JTextArea("");
TextArea3.setBounds(50,110, 127,20);
JButton button =new JButton("Click Here");
button.setBounds(140,130,95,30);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
}
});

Tell me that the below code does what you want and I will add explanations.

}
public static void main(String[] args) {

}
}
This is what it looks like when I run it (before clicking on the button).

You have to split both textarea word and check if first textarea word is matched with second textarea word, If match print it in third textarea.
Here down is example:
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
class CompareWord{
public static void main(String[] args) {
JFrame f;
JLabel lbTextLabelt1, lbTextLabel2, lbTextLabel3;
JTextArea TextArea, TextArea2, TextArea3;
JButton button;
f = new JFrame("new Frame");
lbTextLabelt1 = new JLabel("1:");
lbTextLabelt1.setBounds(50, 10, 120, 20);
lbTextLabel2 = new JLabel("2:");
lbTextLabel2.setBounds(50, 70, 120, 20);
lbTextLabel3 = new JLabel("3:");
lbTextLabel3.setBounds(50, 140, 120, 20);
TextArea = new JTextArea("Welcome to javatpoint");
TextArea.setBounds(50,30, 120,30);
TextArea2 = new JTextArea("Welcome to javatpoint");
TextArea2.setBounds(50,90, 127,30);
TextArea3 = new JTextArea("");
TextArea3.setBounds(50,160, 127,30);
button = new JButton("Click Here");
button.setBounds(120,200,95,30);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
String str1 = TextArea.getText(); // 🍎 🥭 🍊;
String str2 = TextArea2.getText(); // 🥭 🍊 🍌
String str3 = "";
String arrStr1[] = str1.split("//s+");
String arrStr2[] = str2.split("//s+");
List<String> wordsOfFirstStr = Arrays.asList(str1.split(" "));
for (String wordsOfSecondStr : str2.split(" ")) {
if(wordsOfFirstStr.contains(wordsOfSecondStr))
{
str3 += wordsOfSecondStr + " ";
}
}
TextArea3.setText(str3);
}
});
f.add(lbTextLabelt1);
f.add(lbTextLabel2);
f.add(lbTextLabel3);
f.add(TextArea);
f.add(TextArea2);
f.add(TextArea3);
f.add(button);
f.setSize(400, 400);
f.setLayout(null);
f.setVisible(true);
}
}
Output:

component must be showing on the screen to determine its location when changing JCOMBOX

I am receiving this error when i change items in the Jcombobox, nothing breaks it just shows this error, is there anyway to just throw it so it doesn't show up. everything still works fine, but if you wish to have a look at the code. i will post below.
Error message:

Don't create multiple JComboBoxes and then swap visibility. Instead use one JComboBox and create multiple combo box models, such as by using DefaultComboBoxModel<String>, and then swap out the model that it holds by using its setModel(...) method. Problem solved.

How to pass an object argument to a method called in actionPerformed?

I am writing a stock control system program for a school project. This is the last thing I need to do, but seeing as I am a relative Java noob, I kindly request your assistance.
I have a DisplayRecord class, which is created by taking String input from a "search" JTextField in the Search class, finding the Object (Product p) it's linked to, and passing it to the displayRecord method. This part works perfectly.
I want to take that Product p and pass it to the EditProduct class or the DeleteRecord class (depending on the JButton pressed) so the user can then edit the Name, Quantity or Cost of that same Product. Here are my DisplayRecord, EditProduct and DeleteRecord classes. I have no idea what to do.

I'm sorry for the massive post and text wall but I honestly have no idea where my problem is or how to work around this problem (and I'm also new to StackOverflow). Can anyone help me?

It seems to me that DisplayRecord can only display one Product at a time. If that is indeed the case, you can store that Product in a field and then access it from actionPerfomed().

JButton + radiobox + checkbox

I'd like this program I have to have some kind of "sum" button which will add in the column "Description" summarised information about the movie. Lets say I have "die hard" as a title, age 7 from radiobutton, and horror selected from the checkbox. Pressin the button would put "Die hard, 7, horror" under the column. I have no idea how to aproach this case.

You need to declare your variables either before you try to access them, or declare them global, which I did. I prefer this way.
Use .pack() on your frame to when you start the program, something actually shows.
Learn to use LayoutManagers for a better look.
Use arrays of RadioButtons and CheckBoxes so its easier to loop through them. I has to manually write a bunch of if statements, which would not be necessary if I could loop through them.
To get is a RadioButton or CheckBox is selected, use .isSelected()
.setVisible(true) after you add all your components.
Here's is your refactored code. I did nothing else to it, but fix the issue posted in your question. It now adds the info the desciption, when you hit the Add Film button.

Radio buttons and Check Buttons don't work like textfields. In a textfield, the useful values are picked up from the "text" member (example: getText()). A radioButton instead defines a set of fixed choices (well, you can make them dynamic, but it doesn't worth it, there are better components for that kind of work) like "yes" and "no". Usually, when you pickup some rabiobutton, you use the isChecked() method (returns boolean, it may be isChecked(), I don't remember) to react in one way or another. Example:
String age = 0;
if(sevenbutton.isSelected()){
age = 7;
}
Nonetheless, I think you can get the value from the text in the sevenbutton using getText(), but you're gonna need to check which radiobutton is checked anyway. A checkButton works in a pretty similar way, but for non-exclusive choices, so you need to use the isSelected() method, or similar, anyway.
Your method should look like:
private void addMovie(){
String age = "0";
String gender = "";
//Evaluate radioButtons
if(sevenbutton.isSelected()){
age = 7;
}
//Evaluate checkbuttons
if(Horror.isSelected()){
gender = gender+" horror";
}
String movie = film+" "+age+" "+gender;
//do anything else
}

Moving from one frame to another in java swing

I'm just making a small application on window builder and need some help with it. I've made 2 frames individually and I don't know how to specify the action of the button in such a way that when I click on the 'next' botton in the first frame, I want it to move to the second frame.

Having multiple JFrame instances in one application is bad usability
Consider using something like a CardLayout instead.

Modify like this-
JButton btnNext = new JButton("Next");
btnNext.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
second_add second = new second_add();
setVisible(false); // Hide current frame
second.setVisible(true);
}
});

You can navigate to a frame by creating its object and using setVisible method to display it. If you want to do it on a button click, write it inside its event handler.
JFrame o = new JFrame();
o.setVisible(true);
dispose(); // This will close the current frame

The quick and dirty solution would to set the first frame's visibility to false and the second frames visibility to true in your buttonclick action. (see Sajal Dutta's answer)
But to have a consistent behaviour even for more than 2 frames, let each frame be stored in a HashTable in your main class (class holding the main method and not extending JFrame) with the ID being the order of the frame (first frame D 1, second: ID 2, etc.).
Then create a static method
public void switchFrame(JFrame originatingFrame, int NextFrame){
originatingFrame.this.setVisible(false);
((JFrame) myHashTable.get(NextFrame)).setVisible(true);
}
in your main class which can be called from each frame using
mainClass.switchFrame(this, IdOfFrameYouWantToGoTo);
that way you can also implement "Back"- and "Skip"-Buttons should you want to create something like a wizard.
NOTE: I did not test this code. This should just be seen as a general overview of how to do this.

The below piece of code will show to navigate from one page to another page in a menu format.
