Whats the wrong with this code?
- by girinie
Hi in this code first I am downloading a web-page source code then I am storing the code in text file. Again I am reading that file and matching with the regex to search a specific string.
There is no compiler error.
Exception in thread "main" java.lang.NoClassDefFoundError: java/lang/CharSequence
Can anybody tell me Where I am wrong.
