Change Default Cursor to Hand Cursor in Java

[JimmySavel]

In this tutorial, we will create a program that will change the default cursor into a hand cursor in java like the image below.

So, now let's start this tutorial!

1. Open JCreator or NetBeans and make a java program with a file name of jCursor.java.

2. Import java.io package. Hence the cursor class is in the input/output library. Import also javax.swing package because we will use JFrame and setCursor method here in the frame.

1. import
   
   javax.swing.*
   
   ;
   
2. import
   
   java.awt.*
   
   ;
   

3. In your class name make it sure it extends JFrame.

1. public
   
   class
   
   jCursor extends
   
   JFrame
   
   {
   

4. Now, create a constructor that is the same with the file name.

1. public
   
   jCursor(
   
   )
   
   {
   

Create an instance of a Cursor class with a variable cursor and set it into Hand Cursor.

1. Cursor
   
   cursor =
   
   new
   
   Cursor
   
   (
   
   Cursor
   
   .HAND_CURSOR
   
   )
   
   ;
   
2. this
   
   .setCursor
   
   (
   
   cursor)
   

For window characteristics:

1. this
   
   .setDefaultCloseOperation
   
   (
   
   JFrame
   
   .EXIT_ON_CLOSE
   
   )
   
   ;
   
2. this
   
   .pack
   
   (
   
   )
   
   ;
   

5. In your Main, create a JFrame component that will hold all components. This will set the visibility to True, set the size, location, and has the title of the program.

1. public
   
   static
   
   void
   
   main(
   
   String
   
   [
   
   ]
   
   args)
   
   {
   
2. JFrame
   
   cur =
   
   new
   
   jCursor(
   
   )
   
   ;
   
3. cur.setTitle
   
   (
   
   "Hand Cursor"
   
   )
   
   ;
   
4. cur.setVisible
   
   (
   
   true
   
   )
   
   ;
   
5. cur.setSize
   
   (
   
   300
   
   ,250
   
   )
   
   ;
   
6. cur.setLocation
   
   (
   
   250
   
   ,300
   
   )
   
   ;
   
7. }
   

Press F5 to run the program.

Full source code:

1. import
   
   javax.swing.*
   
   ;
   
2. import
   
   java.awt.*
   
   ;
   
3. 
   
4. public
   
   class
   
   jCursor extends
   
   JFrame
   
   {
   
5. 
   
6. public
   
   jCursor(
   
   )
   
   {
   
7. Cursor
   
   cursor =
   
   new
   
   Cursor
   
   (
   
   Cursor
   
   .HAND_CURSOR
   
   )
   
   ;
   
8. this
   
   .setCursor
   
   (
   
   cursor)
   
   ;
   
9. 
   
10. this
    
    .setDefaultCloseOperation
    
    (
    
    JFrame
    
    .EXIT_ON_CLOSE
    
    )
    
    ;
    
11. this
    
    .pack
    
    (
    
    )
    
    ;
    
12. 
    
13. 
    
14. }
    
15. 
    
16. public
    
    static
    
    void
    
    main(
    
    String
    
    [
    
    ]
    
    args)
    
    {
    
17. JFrame
    
    cur =
    
    new
    
    jCursor(
    
    )
    
    ;
    
18. cur.setTitle
    
    (
    
    "Hand Cursor"
    
    )
    
    ;
    
19. cur.setVisible
    
    (
    
    true
    
    )
    
    ;
    
20. cur.setSize
    
    (
    
    300
    
    ,250
    
    )
    
    ;
    
21. cur.setLocation
    
    (
    
    250
    
    ,300
    
    )
    
    ;
    
22. }
    
23. }
    

Hope this helps! :)
