In this article, we will learn how to merge the contents of all the text files in a directory into a single file using Java. It reads the data from each file and writes it into a new file while ensuring all data is stored in an organized manner. You’ll ... Read More

In this article, we will learn to find the common divisors of two numbers using Java. The program will use a recursive method to calculate the greatest common divisor (GCD) of the two numbers, and then determine how many divisors are shared by both numbers. The output will display the ... Read More

In this program, we will perform an iterative quick sort in Java to sort an array of integers. Instead of using recursion, the program uses an iterative approach with an auxiliary stack to manage the sorting process. The output will display the sorted array after applying the quick sort algorithm. ... Read More

In this article, we will learn how to count the number of elements with odd factors (i.e., perfect squares) in a given range using Java. Perfect squares have odd divisors, and we can calculate them by counting the perfect squares in the specified range. Problem StatementGiven a range defined ... Read More

In this article, we will understand how to multiply two matrices using multi-dimensional arrays in Java. The matrix has a row and column arrangement of its elements. A matrix with m rows and n columns can be called as m × n matrix. Individual entries in the matrix are called ... Read More

In this article, we will learn to write a program for shell sort using Java. In the program, we’ll apply this technique to sort an array and observe how the algorithm optimizes the sorting process by reducing the interval between elements. Shell sort Shell sort is a sorting technique that ... Read More

In this article, we will understand how to print the left triangle star pattern using Java. The pattern is formed by using multiple for-loops and print statements. Problem Statement Write a Java program to print the left triangle star pattern. Below is a demonstration of the same − Input Enter ... Read More

To convert HH:MM:SS to seconds with JavaScript, we will be using simple arithmetic operations like mltiplication and addition. We will be understanding this conversion with two example codes and their stepwise explanation. In this article, we are given a time in HH:MM:SS format and our task is to convert HH:MM:SS ... Read More

In this article, we will learn how to generate a string representation of the contents of arrays in Java. Using Arrays.deepToString() transforms arrays into readable strings, making it easy to visualize their structure. This method is particularly useful for one-dimensional and multidimensional arrays. Problem StatementGiven arrays with varying structures, ... Read More
