        String[] arr = fruits.split("~");
        String last = "";  //Last string i need
        if (arr.length > 0 )

//The result

last: apple

//but i want in this case the value of last must be "" because afer "apple" have "~".

Sorry my bad english.

Answer 1

I'm guessing that you are looking for split("~",-1) . By default split removes empty strings ( "" ) from the end, but with negative limit it will leave them.
