I am looking through a piece of code and I cannot figure out what this does. I have seen it in other code but as I am just learning java, I was hoping someone could tell me about it. Here is the code snipet:
line = line.replaceAll("\t", " ");
My question is what does \t do in Java???
\t is an escape sequence that represents a tab. When a String contains a \t in it, a tab will be shown when that String is displayed in the terminal (however, this does not always work in components).
Partly related to regular expression, the code is finding any tab indentation and replacing it with a single space...check regular expression and escape sequences for more information regarding the \t
