Remove all occurrences of char from string

Question

I can use this:

String str = "TextX Xto modifyX"; str = str.replace('X','');//that does not work because there is no such character '' 

Is there a way to remove all occurrences of character X from a String in Java?

I tried this and is not what I want: str.replace('X',' '); //replace with space

Answer 1

Try using the overload that takes CharSequence arguments (eg, String) rather than char:

str = str.replace("X", ""); 

Answer 2

Using

public String replaceAll(String regex, String replacement) 

will work.

Usage would be str.replace("X", "");.

Executing

"Xlakjsdf Xxx".replaceAll("X", ""); 

returns:

lakjsdf xx
