What is a Reverse List? Reverse a list is an operation of swapping or interchanging the elements position into a particular list. While you are writing a code in Java, you can easily reverse the order of a certain flow. It is a conventional way of any programming language in computer science. The reverse () method is a collection of class which reverses the position of first element to last element. Last element will earn the first position itself after the termination of the process. A list is an interface where the class method is denoted as a signature with ... Read More

Linked List and Pointers In Java Linked list is liner data structure in Java environment, which use to store the elements in an adjacent manner. A linked list contains with some addresses and pointers which are used to create a link between the elements present in a list. There are two types of elements present in a linked list. Those are - data element and address element. The value of an element indicated by the data part where the address part helps to create a link between the elements aka node. In Java there is an another concept of ... Read More

We can use an array loop to return back the largest element from a list. Primarily this method, known as the comparison model. The maximum number present here in a certain list will be compared with the all elements present in that particular list. The process considers “n” as a number of inputs which will store as data value in an array. After that the program will display the largest element on the output console after refining the loop. In this article today; we will help you to understand and write some Java code by which you can find the ... Read More

What is the Odd Position in a List? In Java, a List does not have predefined odd and even positions. However, if one considers the first position as index 0, then an odd position in the given List would be any index that is not divisible by 2. To determine if a position is odd, use the modulo operator (%).   How to Find Elements at Odd Position in a List? Below approaches are followed to find out the elements at the odd position in a list − By dividing index with 2 ... Read More

Suppose you are given a set of numbers, your task is to write a Java program to print their summation. To find summation, you need to add all the given numbers with the help of addition operator. In Java, a set of numbers can be represented by an array. Let's understand the problem with an example − Example Scenario: Input: number_set = 34, 11, 78, 40, 66, 48; Output: summation = 277 Sum of all the numbers is 277 as 34 + 11 + 78 + 40 + 66 + 48 = 277. Using Iteration The most ... Read More
