Delete Special Charecters form the String

[Saathvik Reddy]

Hi,

I have a String s1 = "abc@!&def(*)";
I want to delete all the special charecters from the String s1.
The expected result should be s1 = "abcdef"

How can i achive this?

Thanks,

s1.replaceAll("[^\\w]", "")

This will look for all substrings matching the regular expression "[^\w]" which means everything except a word character (0-9, a-z, A-Z and _), and then replace them with the empty string.

If you thing that a word character is still too lenient, you can use "[^a-zA-Z0-9]", or even "[^a-zA-Z]".
