Difference between Java and JavaScript.
As we know, both Java and JavaScript are programming languages and are used in application development. But there are significant differences between the languages, which we will discuss below. Java Java is a high-level language that is also a platform-independent language. It is mainly used in the development of web applications, mobile applications, games, etc. Java is a statically typed language, which means that the code must be checked for errors before it runs. JavaScript whereas JavaScript is a dynamically typed language, which means that the code is checked for errors while it runs. JavaScript is a client-server-side language, which ...
Read MoreJava program to count the child of root node in a JTree
In this article, we will go over a Java program that counts the number of child nodes of the root node in a JTree using Java. This program uses the getChildCount() method to retrieve and display the count of direct child nodes under the root. This is helpful for applications involving hierarchical structures, like directories or organizational charts. Steps to count the child of the root node in a JTree Following are the steps to count the child of the root node in a JTree −Import the necessary classes JFrame, JTree, and DefaultMutableTreeNode from java.swing package.Create a main class named SwingDemo.Define the ...
Read MoreJava program to find the surface area and volume of cuboid
In this article, we will learn how to compute a cuboid's surface area and volume using Java. A cuboid is a three-dimensional object with six faces in a rectangle shape, which means it has sides of different lengths and breadth. The difference between a cube and a cuboid is that a cube has equal length, height, and breadth, whereas these three are not the same in cuboids. Problem Statement Write a program in Java to find a cuboid's surface area and volume. Below is a demonstration of the same − Input Length= 6; Width= 7; Height= 8; Output Volume Of the Cuboid is ...
Read MoreNumber of pairs with maximum sum in C++
We need to find a number of all the pairs that has the maximum sum, In a given array of integers. A pair consists of two numbers, and the sum is simply the result of adding them. We will see multiple solutions to this problem, starting with a naive (brute force) approach and moving to more optimized solutions. Below is the list of approaches we will cover in this article: Brute Force approach using two loops Max Sum Pairs with Sorting ...
Read MoreCreate a Date object using the Calendar class in Java
In Java, we can create a date object using the calendar class, which gives us more control on date and time. We will discuss the process in this article. What is the Calendar class? In order to understand the usage of we must know what is the calendar class. The Calendar class allows us to work with date and time more easily than Date class. like, we can set specific parts of the date, like month, year, and day. For using Calendar class, import the following package. import java.util.Calendar; Now, let us create an object of Calendar class. Calendar ...
Read MoreJava program to demonstrate the call by value
In programming, functions often require parameters to be passed to them to be called or invoked. There are 2 ways to call functions, the 1st being call by Reference and the 2nd being call by value. In this article, we are going to demonstrate call by value in Java. Call by value is a method in which the value of the argument is passed as a copy to the function, hence any change made to this argument inside the function will not affect the original value of the argument beyond the scope of this function. To help understand these concepts ...
Read MoreNatural Numbers in C++ Program
In this article, we will cover C++ programs to work with natural numbers. we use natural numbers in various operations, such as indexing arrays, performing loops, and validating user input. we will also write code to demonstrate how natural numbers can be used for these purposes in C++. Natural Numbers are a set of positive numbers, starting from 1 and going to infinity. natural numbers are: 1, 2, 3, 4, 5... etc In C++, understand concepts like conditions, loops, and how we store and manipulate variables. We will provide everything you need to know about natural numbers along with programs. ...
Read MoreJava program to read a large text file line by line
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 MoreJava program to print unique values from a list
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 MoreJava program to add period to LocalDate
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. ...
