Splitting String with Regular Expression

Question

Hi I really don't understand Regular Expressions :P

This is the input string:

"{\"Name\", \"Surname\", \"Age\", \"Other string with letters and numbers\"}"

And this is the output array of strings that i want:

Name;
Surname;
Age;
Other string with letters and numbers

In other words, i have to eliminate ", { and ,

I think he means "{\"Name\", \"Surname\", \"Age\", \"Other string with letters and numbers\"}" — Federico klez Culloca

Any character list can be a string.. if he says this is the string, maybe this is the string! — Kyle Wild

Where's this data coming from? Is it JSON? If so, there are several libraries out there to aid in marshalling/unmarshalling JSON content. — Rob Hruska

This will match all the terms you specify:

\"(.*?)\"

    String str = "{\"Name\", \"Surname\", \"Age\", \"Other string with letters and numbers\"}";
    String strArr[] = str.replaceAll("\\}|\\{|\"", "").split(",");
    for (String tmpStr : strArr) {
        System.out.println(tmpStr);

    }

Output:

Name
Surname
Age
Other string with letters and numbers

You've forgotten to remove double quotes from the input string

Perhaps he only asked for a regex because he didn't know there's a perfectly good split() method? :)
