[a-zA-Z0-9_.$]+[.]txt ::: This regex can also take "...txt" file name.. (two dots, then .txt) . But this is an invalid file name. Could you please let me know whether I am right or wrong?
Sir, in this example of extracting all the mobile numbers, if a number of the form 929292929292 is present which is not a valid mobile number, it will still extract it as a seperate mobile number. How to overcome this without breaking the single line into multiple tokens??
@@saurabhprakash3831 line will contain other chars too, so it may return false.. it will return true only when there is only number present in the line
I got the same doubt...we can't even use stringtokenizer here as there is no guarantee that normal text and mobile number are separated with space or any other character...if there is any solution..please post here..
sir only these characters (/ \ : * ? " < > |) are not allowed in file names, so if i am making a file with name aman !£$¬`jain.txt than how can i make regular expression for this? i need to exclude only these 9 characters.
