This tutorial introduces how to sort array elements in Java and lists some example codes to understand it. There are several ways to sort an array elements, like Arrays.sort(), sorted(), and parallelSort() methods, etc. Let’s see the examples. Sort Array Elements Using the sort() Method in Java.In this example, we first utilize the Scanner class to accept user input and save the array size in the size variable.

06:10. An Array of Objects is created using the Object class, and we know Object class is the root class of all Classes. We use the Class_Name followed by a square bracket [] then object reference name to create an Array of Objects. Class_Name[ ] objectArrayReference; Alternatively, we can also declare an Array of Objects as :

The Java Array.sort method takes an array B as input and sorts it according to the compare(a, b) method of the array's elements. So if the array stored Integer objects, it would sort them according to Integer.compare(a, b) by default. This just sorts the integers in increasing order.May 17, 2021 · 1 (A)Ascending Order. This sort () Method accepts the list object as a parameter and it will return an ArrayList sorted in ascending order. The syntax for the sort () method is like below.

Arrays is a class in the java.util package, which has a sort method. By calling your own class Arrays , you hide the java.util one from your code (this is sometimes called "shadowing"), so the Arrays.sort(names); line is trying to use a sort method on your class (and it doesn't have one).

After sorted the array you can easily pick up the minimum and maximum value from the sorted array, first element and the last element of the array. For calculate the average you have to use separate method as you used or you can use static variable to calculate the total inside the sorting method.
