Program to convert Primitive Array to Stream in Java

An array is a group of like-typed variables that are referred to by a common name. An array can contain primitives data types as well as objects of a class depending on the definition of the array. In case of primitives data types, the actual values are stored in contiguous memory locations. In case of objects of a class, the actual objects are stored in heap segment. A Primitive array is an array which is defined with the help of the primitive wrapper classes, instead of objects. Example: Integer a = new Integer(4); When a Primitive Array is converted into a Stream, primitive Streams will be obtained like IntStream, DoubleStream and LongStream. Examples:

Input: Double Array: [1.2, 2.4, 3.6, 4.8, 5.0] Output: DoubleStream: [1.2, 2.4, 3.6, 4.8, 5.0] Input: Integer Array: [1, 2, 3, 4, 5] Output: IntStream: [1, 2, 3, 4, 5]

Below are methods to convert Primitive Array to Stream in Java:

1. Using Arrays.stream(): Algorithm:
   1. Get the Array to be converted.
   2. Convert the array into Stream using Arrays.stream() method by passing the array as the parameter.
   3. Return the formed Stream
   Program:
   Output:

   Array: [3, 2, 5, 4, 1]
   Stream: [3, 2, 5, 4, 1]
   

2. Using IntStream.of(): The IntStream.of() method creates a Stream directly with the primitive values or collection passed as the parameter. Algorithm:
   1. Get the Array to be converted.
   2. Convert the array into Stream using IntStream.of() method by passing the array as the parameter.
   3. Return the formed Stream
   Program:
