问题
I know that it is possible to write double quotes in Java strings by putting \ symbol before them. But if double quotes are used a lot in a string, is there a way to mark the string once, so there won't be a need to write the \ symbol before each? (just like in C#, it is possible to put the @ symbol before the string)
Example:
String quotes = @"""""""""""""""""""";
instead of
String quotes = "\"\"\"\"\"\"\"\"\"\"\"";
回答1:
You can't. But if you are too lazy to escape each of the double quotes, there are some trick that can do that. For example:
String quotes = "....................".replace(".","\"");
System.out.println(quotes);
output: """"""""""""""""""""
回答2:
No, there is no such way to write a String literal with unescaped quotes.
You can write the text externally and load it at runtime.
回答3:
There is no way to escape all subsequent double quotes in code (that I know of). But, I recommend against hard-coding String literals. Instead, I suggest you use a ResourceBundle (or even Properties). One benefit being you don't have to escape String(s) you read in that way.
