Java Parsing Strings in Strings

Hello,

Curious issue...
I have a requirement to parse out an incoming string with a string embedded in the string. i.e.
String myString = {"/12345hnd/"a new string"/679hh/"};
where the slashes,"/", are a part of the message and are the key to the parser of a new field in the
stream-of-things. I have tried split() and StreamTokenizer with no success. Since the quotes are an actual part of the message I cannot replace them with a single quote as in " ' " for the recognizer.
Eclipse/Java is not happy with my test setup because it complains bitterly about the string-in-a-string, when I test my Parser.

Curious....

Thank  You

You need to escape the double quotes (").  

You will have to do something like this:
String myString = "\"/12345hnd\"/a new string\"/679hh\"/";
		
String[] myValues = myString.split("\"/");
 
for(String s : myValues) {
    System.out.println(s);
}

Hello,

Yes, Neat...Now some wrinkles...The slashes represent the field delimeters. How to split() along the delimeters while retaining only the escapes of the quoted Strings, so that the quoted strings are also extracted along with the other fields.

Thank You for the mental prodding...

Further analysis has revealed that the "with wrinkles" solution is to make the spit() regex as follows:
("/"); and include the quoted Strings as escaped.

This permits the use of the slashes as delimeters and provides the quoted string intact.

Anyway, yes not a big deal as you found no major wrinkles to end up with "a string".
String myString = "/\"12345hnd\"/\"a new string\"/\"679hh\"";
		
String[] myValues = myString.split("/");
		 
for(String s : myValues) {
    System.out.println(s);
}
