Question

I’ve a string that consists of duplicate values.I’m using split() method to split it into substrings.The problem is split() returns array of different values and i need to retain duplicate values.how to achieve this?

Answer 1

split doesn’t remove dupliates. It returns an array not a set.

String text = "dup dup dup dup dup dup dup dup";
String[] parts = text.split(" ");
System.out.println(Arrays.toString(parts));

prints

[dup, dup, dup, dup, dup, dup, dup, dup]
