Chapter 19, Problem 9RE

Explanation of Solution

Five different ways of producing an “IntStream”:

Option 1: Creating an “IntStream” from individual integers or from array:

IntStream stream= IntStream.of(2,5,4,3,6,9);

int[] arr= {4,3,2};

stream= IntStream.of(arr);

In the above code snippet, an object is created for “IntStream” and it holds the set of integers values. An integer array “arr” is created to hold the array values and the created array is parsed to the “IntStream.of()”.

Option 2: Creating an “IntStream” from a range of integers:

IntStream stream= IntStream.range(a,b);

In the above expression, the “range()” method returns a sequential ordered “IntStream”. The parameter “a” holds the initial value and parameter “b” holds the upper bound value.

Option 3: Creating an “IntStream” from a random range of integers:

Random rand =new Random();

IntStream toss=rand...
