Java Program to Illustrate a Method with 2 Parameters and without Return Type
A method without a return type is termed a void method since it returns nothing. This method can accept multiple parameters. In this tutorial, we will implement Java programs illustrating a method with two parameters and without return type. First of all, we are going to get acquainted with the syntax, examples, and, finally implementation. Syntax public static void method_name (int parameter1, int parameter2) Here, public − It is the access specifier specifying who can access this method. static − It is mandatory to make the method static to avoid errors. void − it denotes that this method returns ...
Read MoreJava Program to Get Year from Date
In our day to day life, there is a huge data being generated in this real world. Among the information generated, Dates are generally used for various things such as scheduling an appointment, planning for day-to-day activities. While working with dates in programming, extracting the year from a specific date can be a common task. We can extract the Year from a particular Date using different in-built functions in Java programming language. In this article we will be discussing different approaches for extracting year from a particular date. Example Input: "13-07-2000" Output: 2000 Example Input: "1997/07/13" Output: 1997 ...
Read MoreJava Program to Find G.C.D and L.C.M of Two Numbers Using Euclid\'s Algorithm
Euclid’s Algorithm is an efficient algorithm which helps us to find G.C.D and L.C.M of two numbers. In this article, we are learning to write a Java program to find the G.C.D and L.C.M of two numbers using Euclid’s Algorithm. G.C.D. of two numbers G. C. D, known as Greatest Common Divisor is the highest common factor that divides the two given numbers exactly. Now let us look into an example and calculate the G.C.D of a two numbers. Factors − In mathematics, Factors are the numbers that can divide a given number. Ex − 8 can be divided ...
Read MoreJava Program to Find Chromatic Index of Cyclic Graphs
Chromatic Index of a graph is the parameter which indicates the minimum number of colours needed to colour all the edges of graph such that no two edges sharing the common vertex have same coloured edge. In this article, we will discuss how to find the chromatic index of cyclic graphs using the Java programming language. What is a Cyclic Graph? Cyclic Graph is a graph which consists of at least one cycle path in that particular graph. Cyclic path is a path that starts from a specific node and ends at the same node. What is Graph Colouring? ...
Read MoreJava vs C#
Java is a dynamic, secured and class based high level object oriented programming language developed by Oracle Corporation. On the other hand; C# is a .Net Framework object oriented programming language developed by Microsoft. Java and C# both are the general purpose programming paradigm or basically known as the imperative environment for coding. And these two languages are capable to provide some high level results as output. In a broad view there are many differences between these two OOPs − Java Runtime Environment designed to run a Java code where C# runs on CLR Environment (Common Language Runtime). Java ...
Read MoreJava Program to Compute the Sum of Numbers in a List Using For-Loop
Introduction Java is a popular programming language that is used for developing a wide range of applications, including those that involve working with lists of numbers. One common task is to compute the sum of numbers in a list, which can be accomplished using a for-loop. In this approach, we first create a list of numbers, then initialize a variable to hold the sum. We then use a for-loop to iterate over each element in the list, adding it to the sum variable. After the loop has completed, the sum variable contains the total sum of all the numbers in ...
Read MoreJava Program to Compute the Area of a Triangle Using Determinants
Introduction The Java program to compute the area of a triangle using determinants is a concise and efficient program that calculates the area of a triangle given the coordinates of its three vertices. This program is useful for anyone studying or working with geometry, as it demonstrates how to use basic arithmetic and algebraic calculations in Java, and how to read in user input using the Scanner class. The program prompts the user to enter the coordinates of three points of the triangle, which are then read in and used to calculate the determinant of the matrix of coordinates. The ...
Read MoreJava Program to search ArrayList Element using Binary Search
Searching is a sorting process to find a particular information from a set of random elements. In a Linear Data structure, there are two types of searching process - Linear Search Binary Search Linear search is a simple searching method by which we can find an element from a data source in a sequential manner. For this searching process the best execution time is 1 and worse is always considered as n. Binary search is a searching process of a particular key element from a stock of multiple elements which follows divide and conquer approach. In this search ...
Read MoreJava Program to Check the Accessibility of an Static Variable By a Static Method
Introduction In Java, we can define variables and methods as static. A static variable or method belongs to the class itself rather than to the individual objects of the class. Therefore, we can access a static variable or method using the class name, without creating an object of the class. In this program, we will explore how to check the accessibility of a static variable by a static method. We will define a class with a static variable and a static method that accesses the variable. We will then call the static method to check if it can access the ...
Read MoreBest Practices for Deploying Hadoop Server on CentOS/RHEL 8
Hadoop is an open-source framework that is used for distributed storage and processing of large datasets. It provides a reliable, scalable, and efficient way to manage Big Data. CentOS/RHEL 8 is a popular Linux distribution that can be used to deploy a Hadoop server. However, deploying Hadoop on CentOS/RHEL 8 can be a complex process, and there are several best practices that should be followed to ensure a successful deployment. In this article, we will discuss best practices for deploying a Hadoop server on CentOS/RHEL 8. We will cover following sub-headings − Pre-requisites for Deploying Hadoop on CentOS/RHEL 8 ...
