Problem

Develop a Java application that provides a GUI that contains

-a single-selection list box, LB1

-a second list box, LB2

-a label "----->" that indicates the direction of movement of items between the list boxes, namely, from LB1 to LB2

-a command button Exit with legend "Exit"

When your application begins it must do the following initialization

-Load LB1 with items shown in the Sample Program Dialogue. (Note The items contains the course numbers for undergraduate Computer Science courses, one course-number-string per file record).

-Empty (clear the contents of) LB2.

When your application is running it must respond to the following GUI events

-Double-left-clicking on an item in LB1 causes that item to be moved from LB1 to LB2. (Note A move copies the item from LB1 to LB2 then deletes the item from LB1.)

-Typing Shift+M after selecting exactly one item in LB1 causes the selected item to be moved from LB1 to LB2. Note Shift+M keyboard events must be ignored when no item is selected in LB1.

-Single-left-clicking the Exit command button causes the application to normally terminate.

PLEASE take screenshot of GUI when completefd

LB1.setFont(font);

Input records from text file "Problem2.in" and use each record as a single string to initialize

the contents of LB1. Hints (1) Study sequential file input in Section 17.4; and (2) use the

DefaultListModel method addElement().

Place LB1 into the GUI

Define a mouseClicked event handler to handle a double-left-click event for LB1. Note JList does not

provide any special event handling of multiple (2 or more) mouse clicks, so you have to provide

logic that distinguishes between one-click and double-click events. To handle a multi-click mouse

event, add a MouseListener. Hints Use (1) the MouseEvent method getClickCount(); (2) the

DefaultListModel methods getElementAt(), addElement(), and removeElementAt(); and (3) the JList

methods getSelectedIndex() and clearSelection().

Define keyTyped event handler to handle the typing of Shift+M event. Hints Use (1) theKeyEventmethod

getKeyChar(); (2) the DefaultListModel methods getElementAt(), addElement(), andremoveElementAt();

and (3) the JList methods getSelectedIndex() and clearSelection(). Note getSelectedIndex() returns -1

when no item is selected.

// "----->" label

arrow = new JLabel("----->");

Place arrow label into the GUI

// LB2 list box

LB2List = new DefaultListModel();

LB2 = new JList(LB2List);

LB2.setBounds(330,30,200,500);

// "Exit" command button

Exit = new JButton("Exit");

Exit.setBounds(540,510,100,20);

Exit.setFont(font);

// The event handler for the Exit command button (defined below) is coded as an anonymous inner class!
