Question 4[8] Complete the following code to create a GUI that has the same appearance as the given GUI(s). Some GUI objects are already created in the code. You need to create the rest of the objects and complete the code. After that, add event handling functionality to the code so that when the button is clicked, the inputs in the textfields are swapped (Check Fig 1 & Fig 2). You need to perform following tasks to complete the GUI: . . . Create the "Swap" button object Set the frame object's layout properly and call necessary methods Add components to the frame Make the frame visible Perform button click handling [You can also use corresponding AWT classes (Frame etc.) instead of Swing classes (JFrame) if you want] Swapping App abc 123 public class GUITest { public static void main(String[] args) { JFrame frame = new JFrame(); frame.setSize(275, 120); JTextField tf1 = new JTextField(10); JTextField tf2 = new JTextField(10); Swap! // Add your code 1: Complete the GUI Fig 1: Before clicking Swap button // Add your code 2: Complete button // click handling Swapping App } 123 abc Swap!
