Java programming

a) Write a stream pipeline to compute the sum of the odd integers from 10 to 20. b) Use an infinite stream to compute the sum of the odd integers from 10 to 20. c) Suppose you have a List of Strings called stringList. Use the reduce operation to create a stream pipeline that returns a String composed of each element of stringList separated by a comma. As an example, suppose string List contains the Strings test1, test2, and test3. The stream pipeline should return test1, test2, test3.
