Question

I am looking for a Regular expression to match string literals in Java source code.

Is it possible?

private String Foo = "A potato";
private String Bar = "A \"car\"";

My intent is to replace all strings within another string with something else. Using:

String A = "I went to the store to buy a \"coke\"";
String B = A.replaceAll(REGEX,"Pepsi");

Something like this.

Ok. So what you want is to search, within a String, for a sequence of characters starting and ending with double-quotes?

    String bar = "A \"car\"";
    Pattern string = Pattern.compile("\".*?\"");
    Matcher matcher = string.matcher(bar);
    String result = matcher.replaceAll("\"bicycle\"");

Note the non-greedy .*? pattern.
