Remove duplicate values from a string in java

Question

Can anyone please let me know how to remove duplicate values from

String s=\"Bangalore-Chennai-NewYork-Bangalore-Chennai\"; 

and output sh

Answer 1

I'd prefer this which is simpler than all of the above.

public void removeDuplicates() {
  String myString = "Bangalore-Chennai-NewYork-Bangalore-Chennai";

  String[] array = myString.split("-");

  Set hashSet = new HashSet(Arrays.asList(array));

  String newString = StringUtils.join(hashSet, "-");        
}
