Creating a list with repeating element

Question

Is there an utility method in Java that generates a list or array of a specified length with all elements equal to a specified value (e.g [\"foo\", \"foo\", \"foo\", \"foo\"

Answer 1

If your object are not immutable or not reference-transparent, you can use

Stream.generate(YourClass::new).limit()

and collect it to list

.collect(Collectors.toList())

or to array

.toArray(YourClass[]::new)
