This is what I have made by now, I'm trying to do a java project but I really want to see some examples to understand the way i can make it happen.If I want to take all jtextfield components and save it into a file

The first thing we need to do is get the text from a JTextField and store it in a String, like this:
String textFieldVal = yourTextField.getText();
Then, we have to write the value to a text file, like this:
PrintWriter writer = new PrintWriter("textFieldOutput.txt", "UTF-8");
writer.println(textFieldVal);
writer.close();
So, this is what it would look like in your first class:
String textField1Val = jTextField1.getText();
String textField2Val = jTextField2.getText();
String textField3Val = jTextField3.getText();
String textField4Val = jTextField4.getText();
String textField5Val = jTextField5.getText();
String textField6Val = jTextField6.getText();
String textField7Val = jTextField7.getText();
And when you want to save it to a text file:
PrintWriter writer = new PrintWriter("textFieldOutput.txt", "UTF-8");
writer.println("First text field:");
writer.println(textField1Val);
writer.println("Second text field:");
writer.println(textField2Val);
writer.println("Third text field:");
writer.println(textField3Val);
writer.println("Fourth text field:");
writer.println(textField4Val);
writer.println("Fifth text field:");
writer.println(textField5Val);
writer.println("Sixth text field:");
writer.println(textField6Val);
writer.println("Seventh text field:");
writer.println(textField7Val);
writer.close();
However, this will overwrite the file if it already exists, so in your other classes, do this:
try (PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter("textFieldOutput.txt", true)))) {
writer.println(textField1Val);
writer.println(textField2Val);
// etc...
} catch (IOException e) {
}
That way, it will add to the file instead of erasing all the text. I hope this helps!
EDIT:
Here is an example ActionListener referencing a single void with all of the code:
jTextField1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
saveText(evt);
}
});
And somewhere else in your class:
private void saveText(evt) {
String textField1Val = jTextField1.getText();
String textField2Val = jTextField2.getText();
String textField3Val = jTextField3.getText();
String textField4Val = jTextField4.getText();
String textField5Val = jTextField5.getText();
String textField6Val = jTextField6.getText();
String textField7Val = jTextField7.getText();
PrintWriter writer = new PrintWriter("textFieldOutput.txt", "UTF-8");
writer.println("First text field:");
writer.println(textField1Val);
writer.println("Second text field:");
writer.println(textField2Val);
writer.println("Third text field:");
writer.println(textField3Val);
writer.println("Fourth text field:");
writer.println(textField4Val);
writer.println("Fifth text field:");
writer.println(textField5Val);
writer.println("Sixth text field:");
writer.println(textField6Val);
writer.println("Seventh text field:");
writer.println(textField7Val);
writer.close();
}
