正则表达式用于匹配Java中的字符串文字？

在Java中，您可以使用此正则表达式匹配

"

"

boolean valid = input.matches(""[^"\\]*(\\.[^"\\]*)*"");

使用的正则表达式是：

^"[^"\]*(\.[^"\]*)*"$

分手：

^  # line start"  # match literal "[^"\]*       # match 0 or more of any char that is not " and (  # start a group   \         # match a backslash    .          # match any character after    [^"\]*    # match 0 or more of any char that is not " and )* # group end, and * makes it possible to match 0 or more occurrances"  # match literal "$  # line end
