This article explains how to handle XML documents in PHP. XML (eXtensible Markup Language) is defined as a textual markup language designed for both people and computers. It is a format used for storing and moving data between applications. PHP simplexml_load_string() function provided by PHP allows us to parse XML strings with ease and this function will convert XML string into an object for us which can be examined in order to understand XML data. Usong PHP simplexml_load_string() Method PHP simplexml_load_string() function accepts an XML string and returns a SimpleXMLElement object, the object has properties and methods that will ...

Remote Work and Hybrid Work spaces have the strongest growth rates in recent years, primarily due to the advancement in technology and the global pandemic. These models of work have dramatically altered how we imagine the office, balance work and life, and achieve productivity. Let's dive into what each model means, its advantages and disadvantages, and how companies and employees can make the best of them. Remote WorkRemote work or working from home (WFH) is a job type where the employees need not be physically present in the office but can do their job from anywhere, even from home, though ...

Network performance, including throughput and latency, is important for many applications. These include devices that manage wired and wireless systems, such as routers, firewalls, etc. High performance is also crucial for services like video streaming etc. Traditional networks are struggling with performance issues because the hardware they use to send and receive data packets has limitations. The main problem is that these networks rely on the kernel network protocol stack. This approach can be slow and inefficient, leading to delays. As networks handle more and more data, they need high-performance solutions to process traffic faster and more efficiently. What ... Read More
Mean, median and mode are three basic concepts of statistics. These quantities help in understanding the central tendency and distribution of given data. In this article we are going to learn, how we can find the Mode if the Mean and Median of a given array (which is the same as ungrouped data) in C++. Problem statement We are given an array of numbers and we have to find the mode if mean and median are given in C++. Example Input [5, 15, 25, 35, 35, 40, 10] Mean = 20Median = 25 Output 35 Brute Force Approach Mode is ... Read More
In this article, we will understand how to check if a string is empty or null in Java. The string is a datatype that contains one or more characters and is enclosed in double quotes(“ ”). We’ll start by learning to detect these cases directly within the main method, and then we’ll see how to achieve the same result using encapsulation for better code organization and reusability. Problem Statement Write a program in Java to check if a string is empty or null. Below is a demonstration of the same − Input Input string: null Output The string is a null ... Read More
This article includes the way to read text files line by line in Java. Here, the three different methods are explained with examples. Storing a file in text format is important especially when data from one structured /unstructured form is transferred to another form. Therefore, basic file transfer systems integrate the txt file reading and writing process as their application components. Therefore, how to use text file reading and writing methods is also important for making the parsers. Multiple Approaches The given problem statement is solved in three different approaches − By using the BufferedReader ... Read More
In this article, we will learn to print unique values from a List in Java. This program will use a loop-based approach to identify and display only the values that appear once, skipping any duplicates. This approach is helpful when working with datasets where you want to remove repeated items and focus on distinct entries. Problem Statement Write a program in Java to print unique values from a list. Below is a demostration of the same − Input 55, 67, 99, 11, 54, 55, 88, 99, 1, 13, 45 Output The distinct elements in the array are 55 67 99 11 ... Read More
In this program, we will learn to add a specific period to a date using Java’s LocalDate class. By using Java's Period class, we can specify an amount of time (such as months and days) and then add this period to a LocalDate. The program demonstrates how to set a period and apply it to a given date to get a new, updated date. Steps to add Period to LocalDate Following are the steps to add Period to LocalDate − Import LocalDate and Period from java.time package to work with dates and periods. ... Read More
In this article, we will learn how to connect a Java application to a MySQL database hosted on a specific IP address. By specifying the IP address in the connection URL, we can directly connect to the database even if it’s on a different machine. We’ll use the DriverManager.getConnection() method to initiate the connection. Steps to connect a MySQL database via IP Address Following are the steps to connect a MySQL database via IP Address − Import Connection and DriverManager classes from the java.sql package to enable database connectivity. Create a String ... Read More
In this article, we will learn how to check whether a database supports the SQL GROUP BY clause using JDBC in Java. The GROUP BY clause is used to organize identical data into groups in SQL queries, typically following the WHERE clause and preceding the ORDER BY clause. With JDBC, we can determine whether the underlying database supports this clause using the supportsGroupBy() method of the DatabaseMetaData interface. Problem StatementGiven a MySQL database, write a Java program that connects to the database and checks if the database supports the SQL GROUP BY clause.Input Database connection URL, username, and ...
