Which of the following methods in the Stream API can change the type of the elements in a stream?

  • collect()
  • filter()
  • forEach()
  • map()
The map() method in the Stream API is used to transform elements in a stream. It takes a function as an argument and applies that function to each element in the stream, producing a new stream with the transformed elements. This can change the type of elements in the stream if the mapping function converts them to a different type. The other methods listed do not change the type of elements in the stream.
