[FIXED] How to check if string list contains anything other than some value?

Issue

If we have two simple lists where one have only one repeating value:

List<String> states = Arrays.asList("Excelent", "Excelent", "Excelent");

and the other one have one different value:

List<String> states = Arrays.asList("Excelent", "Excelent", "Good");

how can I check if list contains anything other than "Excelent" in this case?

It should looks something like:

private boolean check(List<String> states){
    //Some condition where we can say if there is any item not equal to "Excelent"
}

Solution

There are many ways to solve it.

You can for example streaming it and filter for values different to Excelent

private boolean check(List<String> states){
    return states.stream()
              .filter(item -> !item.equals("Excelent"))
              .count() > 0;
}
