Thread: Save Textfield to an Array

I have a crossword generator project, and the user is going to list in their words in text fields to generate a crossword puzzle from those words.
I need to write a proper code to take in the words from the textfields and save them in an array.
and then save them to a text field. to make it easier for the user to look at his word when he comes back to the application.
I wrote A code, but it doesnt seem to be appropriate because everytime I try to print the array contents it prints nothing.
I might need help with the line that takes the text from a text field and saves it in an array , or a new idea to do it.
I am new to java and not very fimiliar with it.

I am using Netbeans IDE

Hello NorahPoly!
Can you post the code you are having trouble with? Or better yet, a simple program that executes and shows the problem?

Thanks andreas for your replay,

this is my code that takes words from everytext field and save it to an array and then write it to a file, but it doesnt work.

String[] words = null;// = new String[15];

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
words[0] = word1TXT.getText();
words[1] = word2TXT.getText();
words[2] = word3TXT.getText();
words[3] = word4TXT.getText();
words[4] = word5TXT.getText();
words[5] = word6TXT.getText();
words[6] = word7TXT.getText();
words[7] = word8TXT.getText();
words[8] = word9TXT.getText();
words[9] = word10TXT.getText();
words[10] = word11TXT.getText();
words[11] = word12TXT.getText();
words[12] = word13TXT.getText();
words[13] = word14TXT.getText();
words[14] = word15TXT.getText();

try
{
PrintWriter pr = new PrintWriter("blabla");

for (int i=0; i<words.length ; i++)
{
pr.println(words[i]);
}
pr.close();
}
catch (Exception e)
{
System.out.println("No such file exists.");
}
}

okay, find the attachment.. there are 15 text fields. I need to save each word of the textfield in a new line of a .txt file. words do not save in a .txt file,, and a .txt file doesnt happen to be created when i run.

the file cannot be created idk why

I'm going to assume you are using the Swing API? If yes, then JTextField has an inherited getText() method that returns a String.

What kind of array are you wanting to save it to? A String is already an array of characters by default.
