Count occurrences of a number using Java 8 Streams API

In the above example, The arrayOfNumbers is an array of integers basically, and the targetNumber is the number to count occurrences of. The Arrays.stream method of Java 8 is used to create a stream from the array, and then the filter method is used to filter the stream to only include elements that are equal to the specified target number. Finally, The count method returns the number of elements in the filtered stream, which is the number of times the target number occurs in that particular array.
