Hi, i wanted to create a JTextField to receive the user input instead of having the user key in the input through the IDE console. This is my code. Now, my code just runs fine if the user key in the inputs through the console. After running the code, the result i append to text area meaning after the run is complete, a text area will pop out show the results. Now what i wanted to do is i want create a GUI Jtextfield to accept user input rather than having user to key in through the console. This is my code.

}Can anyone guide me to do the text field from the looks of my code ? Thanks. The user receive input from this line of code.

Scanner scanner = new Scanner(System.in);
String word2 = scanner.nextLine();
