Java Programming for Complete Beginners - Java 16 - Step 08 - Stream Intermediate Operations - Sort, Distinct, Filter, a

This video tutorial covers intermediate operations on streams, including sorting, finding distinct elements, and mapping elements to their squares. It demonstrates how to perform these operations on a list of numbers, highlighting the use of methods like sorted, distinct, and map. The tutorial emphasizes the ability to chain multiple intermediate operations on a stream, with a single terminal operation to produce a final result.

What is the result of sorting a stream of numbers?

• A list of unsorted numbers

• A new sorted stream

• A string of numbers

• A single integer

Which method is used to find unique elements in a stream?

• reduce

• filter

• distinct

• map

What happens when you combine 'distinct' and 'sorted' operations on a stream?

• The stream is split into two separate streams

• The stream is sorted and then duplicates are removed

• The stream is filtered and then reversed

• Duplicates are removed and then the stream is sorted

What does the 'map' operation do in a stream?

• It filters out elements based on a condition

• It transforms each element to another form

• It combines all elements into a single result

• It duplicates each element in the stream

How can you print the squares of distinct numbers in a stream?

• Use 'filter' followed by 'map'

• Use 'distinct' followed by 'map'

• Use 'reduce' followed by 'sorted'

• Use 'sorted' followed by 'distinct'
