非法逃脱字符“\” [英] Illegal Escape Character "\"

问题描述

我想得到一个链接的最后的名称，所以我做了

i want to get the name at the final of a link so i did that

if( invName.substring(j,k).equals("\")){
                                 copyf=invName.substring(0,j);}

$ b b

所以eclipse说的字符串文字没有被一个双引号正确关闭

so eclipse said String literal is not properly closed by a double-quote

我如何使用这个char \

how can i compaire String with this char \

推荐答案

字符'\'是一个特殊字符，需要在用作字符串的一部分时进行转义，例如\ 。下面是使用'\'字符的字符串比较示例：

The character '\' is a special character and needs to be escaped when used as part of a String, e.g., "\". Here is an example of a string comparison using the '\' character:

if (invName.substring(j,k).equals("\\")) {...}

字符比较使用类似于以下逻辑：

You can also perform direct character comparisons using logic similar to the following:

if (invName.charAt(j) == '\\') {...}
