List of Keywords in Java

Hi welcome to the Java session. Today we are going to see the list of keywords available in Java.

We already know that keywords are reserved words which are having special meaning to the Java language. Hence we are not allowed to use keywords to name a variable, method or class name etc. A total of 50 reserved words are there in Java.

The list of keywords are:

1. abstract
2. assert (This is added in JDK 1.4)
3. boolean
4. break
5. byte
6. case
7. catch
8. char
9. class
10. const (This is not used)
11. continue
12. default
13. do
14. double
15. else
16. enum (This is added in JDK 1.5)
17. extends
18. final
19. finally
20. float
21. for
22. goto (This is not used)
23. if
24. implements
25. import
26. instanceof
27. int
28. interface
29. long
30. native
31. new
32. package
33. private
34. protected
35. public
36. return
37. short
38. static
39. strictfp (This is added in JDK 1.2)
40. super
41. switch
42. synchronized
43. this
44. throw
45. throws
46. transient
47. try
48. void
49. volatile
50. while

Apart from the above keywords true, false and null might look like keywords, but actually they are not keywords. Still these are not allowed to name a variable.

Do remember that main is not a keyword in Java. That means main can be used for naming a variable. Of course it's a bad programming practice!

All these keywords will be covered in our tutorial. Hope the today session is useful to you.
