What are duplicates in a list? If an integer or string or any items in a list are repeated more than one time, they are duplicates.
If you don't want duplicates, use a Set instead of a List . To convert a List to a Set you can use the following code: // list is some List of Strings Set<String> s = new HashSet<String>(list); If really necessary you can use the same construction to convert a Set back into a List .
Python list can contain duplicate elements.
In Python, is the a simple way to test that all values in a list are equal to one another?
