Java Replacing & Removing Characters in Strings

This video will show you how to remove specified characters, alphabetic letter, numeric values and sub-strings from a string. In this video you will learn to either remove or replace the specified value.

Assuming you want to remove all symbols(I guess thats what you would call it) I would use the ^ with the tools in this video to remove all of them

x = x.replaceAll("[^a-zA-Z0-9]", "");

Basically this is not touching letters or numbers.

If you want to just remove one symbol say just the # sign do this

x = x.replaceAll("#", "");

Of course if you have several replaces needed I would create a method to work through the string to clean it up.

I hope this helps

Can this be used to remove, say, Japanese text from a dumped videogame and replace it with English characters? Intended to replace the kanji menu to an English one.

Thanks for the vid man, one question though. How would I make it so characters such as # and @ are omitted. I understand a-zA-z for letters and 0-9 for numbers, so is there one for all the other characters?

This video works best if you choose 720p and reload so that the text will be clear.

What if you wanted to remove a character but but have a group of them. e.g
5*4*3*2*1* =
How would I remove the "*" after the number 1?
