Question

提问by Batman

I want to add a '\' character to every string in a list of strings... I m doing something like this but it adds 2 backslashes instead.

我想为字符串列表中的每个字符串添加一个 '\' 字符......我正在做这样的事情，但它添加了 2 个反斜杠。

feedbackMsgs.add(behaviorName+"\\"+fbCode);

result is like: "abc\\def"

结果是这样的： "abc\\def"

how to make sure a single backslash is added??

如何确保添加单个反斜杠？

Answer 1

Looks like either your behaviourNameends with a \or fbCodestarts with one.

看起来要么behaviourName以 a 结尾，\要么fbCode以 one 开头。

Answer 2

I've just run a program with the following -

我刚刚运行了一个具有以下内容的程序 -

String s = "test" + "\" + "test2";
System.out.println(s);

And it prints out the following -

它打印出以下内容 -

test\test2

Are you sure there is no \ in the behaviourNameor fbCodevariables?

您确定behaviourNameorfbCode变量中没有 \吗？

Try to Log/print behaviorNamefbCodeand find it yourself !

尝试记录/打印behaviorNamefbCode并自己找到它！

System.out.println(behaviorName);
System.out.println(fbCode);
