In Java, an ArrayList is a resizable array, which is implemented as part of the Java Collections Framework. It is a dynamic data structure that can hold any type of objects, including primitive types such as integers and characters. As per the problem statement we have to read a file into an ArrayList. First and foremost we will take the path of the file as input and then we will apply different method to read the file. Let's start!Example For instance Suppose the input file is “myfile.txt”. After reading the content of the file, the result ... Read More
In this article, we will learn to sort a short array in Java using the Arrays.sort() method. Begin by declaring and initializing an unsorted short array, then sort it and display the sorted array. Arrays.sort() method : This method sorts the elements of array in ascending order which have specified range and specified order. Syntax public static void sort(Object[] a, int fromIndex, int toIndex) Steps to sort short array Following are the steps to sort short array in Java − Declare and initialize an unsorted short array. ...

In this article, we will create a graphical user interface (GUI) using the Swing. The Swing is the GUI framework for Java-based applications Here, we are using the LayoutManager GridBagLayout to center the components of AWT Layouts. We have two components here including a label and we have set the layout as GridBagLayout − JLabel label = new JLabel("Name (Centered Label): "); JTextArea text = new JTextArea(); text.setText("Add name here..."); panel.setLayout(new GridBagLayout()); Steps to center a JLabel in a JPanel with LayoutManager The following is an example to center a JLabel in a JPanel with LayoutManager − ...

Segregation is a process in the field of software engineering where a code is forced to depend on those methods that are not in use. The segregation interface is known as ISP. It splits the interfaces that are vast in nature. In a Java environment, there are lots of advantages to implementing the segregation principle. It increases the readability of the particular code. It also helps to maintain that particular code conveniently. Problem Statement There is an array of 7s and 16s aimlessly. We must segregate the 7s on the left side and the 16s on the right. The basic ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to check if an array is empty or not. An array is said to be an empty array, if the array has zero element or no element in it. Let’s explore the article to see how it can be done by using Java programming language. InstancesTo show you some instances: Instance-1 Suppose the original array is {1, 3}. After checking if it is empty or not the result will be − Array is ... Read More
There is no comparison between Kotlin and Java because one is best than another, so we could not decide which is best. Because Kotlin is a vibrant, advanced software programming language. It is simple to learn, particularly if you are already familiar with Java (it is completely compatible with Java). Kotlin is used to create Android applications, web server applications, and many other things. Java is a well-known software program. It is used to create smartphone applications, web applications, desktop applications, games, and many other things. It depends, as with everything, so we'll take a glance at the main differences ...

The two most popular programming languages are Java and Python. Both are high-level, general-purpose programming languages that are widely used. Developers currently utilize the Java programming language to create web and desktop apps. Python is utilized in the development of machine learning applications and data science. Choosing between the two is challenging. In this article, we will compare whether Java or Python is a better programming language. What is Python? Python is a high-level, object-oriented, dynamic, and multipurpose programming language. Python's syntax, dynamic typing, and interpreted nature make it an excellent scripting language. It supports a variety of programming paradigms, ... Read More
As technology continues to grow and evolve, so does the number of cyber threats. Cybersecurity is now a top priority for many people, businesses, and governments. A secure programming language is a key component of any effective cyber security strategy. Secure Programming is the Key to Data Protection: Why You Need It? A secure programming language is designed to be resistant to attack. It is for preventing malicious code from being executed. It is also to protect data from being stolen. It also provides safeguards to ensure that the code is not easily altered or corrupted. One of the biggest ... Read More
Java is a programming language and it is called by different names for its work. These names are called robust programming, object-oriented programming, secure programming languages, etc. But here we discuss Java as a robust programming language. Java is a robust programming language that can manage run-time errors because it checks the programming code through in run-time and compile time. If a Java virtual machine (JVM) detects a runtime error, it does not report it to the underlying platform. Rather, it will suspend or terminate the program and prevent this from causing any damage to the system. Therefore, we are ... Read More
Java is a programming language that has been used in the real world, it works for commercial websites, financial applications, android applications, scientific applications, and much more. Here, in this post, we will focus on where Java programming language is used the most. Let’s have a look at the below 8 points. 1. Android Apps Android apps are a good place to start if you want to see where Java is used. If you open any app on your Android phone, it is actually written in Java and uses Google's Android API, which is similar to JDK. As a result ... Read More
