Arrayis a collection of elements of same type.For examplean int array contains integer elements and a String array contains String elements. The elements of Array are stored in contiguous locations in the memory
Example of an arrayint[] a = new int[5]; a[0] = 1; a[1] = 2; a[2] = 4; a[3] = 8; a[4] = 16; A pictorial representation of the above example can be as below. 2. Features of an Array Arrays are also a subtype of Object in Java. Arrays are objects so we can fi...

Array allows us to search it’s elements. It provides a method calledindex(x). This method takes in an element,x, and returns the index of the first occurrence of the element. Example 14:Find the index of an element in an array with index() ...
In this example, Comparator.comparingInt(Math::abs) tells the min() method to evaluate values by their absolute magnitudes. The orElseThrow() method throws an exception if the list is empty, ensuring we handle that case safely. Similarly, we can use the max() method with the same comparat...
