问题描述

我想更换一个空格字符到一个连字符我在我的字符串。

 字符串replaceText =AT AT;
replaceText.replace('',' - ');
 

但是当我这样做,我似乎无法取代的角色。我试过的replaceAll()方法,它也不行。

++++++回答+++++++

对不起我的错......深夜节目的结果:(

感谢您的回答,我不能大概回答所有的,所以我将检查的第一个答案

  replaceText = replaceText.replace('',' - ');
 

解决方案

  replaceText = replaceText.replace('',' - ');
 

字符串是不变,它们不能被创建后改变。不知怎的,修改字符串的所有方法都将返回一个新字符串纳入了修改。

I am trying to replace a space character into a hyphen I have in my string.

String replaceText = "AT AT";
replaceText.replace(' ', '-');

but when I do this, I cannot seem to replace the character. I tried the replaceAll() method and it doesn't work either.

++++++Answer+++++++

sorry my mistake.. the result of late night programming :(

thanks for the answer i cant probably answer all so i will check the first answer

replaceText = replaceText.replace(' ', '-');

解决方案

replaceText = replaceText.replace(' ', '-');

Strings are immutable, they cannot be changed after creation. All methods that somehow modify a string will return a new string with the modifications incorporated.
