Its complexity is O(n log(n)). It is a static method that parses an array as a parameter and does not return anything. Other inbuilt java methods allow you to sort your arrays. To use the sort method of arrays, you first need to reference a Java library called Arrays.

The java.util.Arrays package has a static method Arrays.toString(). Hence, to use this static method, we need to import that package. Arrays.toString() accepts an array of any primitive type (for example, int, string) as its argument and returns the output as a string type. A normal array in Java is a static data structure, because you stuck with the initial size of your array. To set up an ArrayList, you first have to import the package from the java.util library: import java.util.ArrayList; You can then create a new ArrayList object: ArrayList listTest = new ArrayList( ); The Arrays class contains various methods for manipulating arrays (such as sorting and searching).

To help your Java journey, in this tutorial, we will learn how to implement and use arrays in Java.

The value returned by this method is equal to the value that would be returned by Arrays.asList(a).hashCode() , unless a is null , in which case 0 is returned. For any two long 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 Long instances representing the elements of a in the same order.

In Java, we can compare two arrays by comparing each element of the array. Java Arrays class provides two predefined methods that is used to compare two arrays in Java. In this section, we will learn how to compare two Arrays using Arrays.equals() method and Arrays.deepEquals() method.

Example: 2016-11-15 2016-11-16 2019-07-07 Java 8 introduced lots of new APIs for parallel processing data sets and streams. One such API is Arrays.parallelSort(). It breaks the array into different sub-arrays and each sub-array is sorted with Arrays.sort() in different threads. Finally all sorted sub-arrays are merged to one array as result.
