Question

Create a graphical spell checker program that The File menu has the three items shown. On Open, the program reads a text file (!) with the current directory set to the directory where your program is located. Save saves the current text in the window to the file selected over a dialog and The Edit menu has one menu item: Spell Check.

Answer 1

HI,

I created the program and added the comments.

File menu is showing open and save and edit will show spell check menu.

1. Open method is reading text file and adding content in text area.its just like working editor program.

2. save menus will save the text area content in new file by swing File Chooser.

3. Edit is a graphical menus and showing Spell checker sub menu.

class SpellCheckMenu  implements ActionListener
{  
              
          JMenu menu, editMenu;  // Main menu which will show file and edit menus
                  JTextArea ta;    //text area where we will display content from the file 
          JMenuItem menuOpen, menuSave, menuSpell;   //menu items which will be added in menus
                  // class constructor
          SpellCheckMenu(){  
          JFrame frame= new JFrame("Menu and MenuItem Example");  
          JMenuBar menubar=new JMenuBar();   // all the menus will be added in this to show on window

public static void main(String args[])
