![]() ![]() The IntStream.of() method function is very similar to using curly braces. This statement will produce an Array of exact 20 integers, from 1 to 20: Īlthough it is not necessary but If you want to include the last element of the range, IntStream.rangeClosed() method can be used instead of range() method: int myArr = IntStream.rangeClosed(1, 20).toArray() The method toArray() is then used with it that convert the range to an Array. It is to be noted that the second parameter is not included, so you will always have to take 1 value greater than the intended. The range() method is used here that takes the start and end of the data sequence as parameters. This code creates an Array of 20 integers, containing the numbers from 1 to 20: While declaring and initializing an Array of integers using streams, the IntStream Java interface is used to create the Array, int myArr = IntStream.range(1, 21).toArray() Int myArr = IntStream.rangeClosed(1, 20).toArray() See the code demonstration below showing the initializing of an integer Array of size 20 using three IntStream methods: int myArr = IntStream.range(1, 21).toArray() It includes the use of multiple IntStream interfaces mentioned in the below example.
