For any two non-null int arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b). The value returned by this method is the same value that would be obtained by invoking the hashCode method on a List containing a sequence of Integer instances representing the elements of a in the same order. Java Arrays. Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type with square brackets:

In Java, an ArrayList is used to represent a dynamic list. While Java arrays are fixed in size (the size cannot be modified), an ArrayList allows flexibility by being able to both add and remove elements. // import the ArrayList package
In Java, Arrays is the class defined in the java.util package that provides sort() method to sort an array in ascending order. It uses Dual-Pivot Quicksort algorithm for sorting. Its complexity is O(n log(n)).
