从字符串中删除所有出现的字符 [英] Remove all occurrences of char from string

问题描述

我可以用这个:

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

有没有办法从 Java 中的字符串中删除所有出现的字符 X?

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

我试过了，这不是我想要的:str.replace('X',' ');//用空格替换

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

推荐答案

尝试使用 采用CharSequence 参数 的重载(例如，String) 而不是 char:

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

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