To compare two arrays in Javascript, there are various approaches we can use. We will be understanding various approaches in this article. When comparing two arrays, we cannot use “==” or “===” operator as it compares the addresses of the memory block to which both the arrays are pointing resulting in a false result. In this article we are having two arrays and our task is to compare two arrays in JavaScript. Approaches to Compare Arrays in JavaScript Here is a list of approaches to compare two arrays in JavaScript which we will be discussing in this article with stepwise ... 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 total number of common divisors. Problem Statement Write a Java program to find and count the common divisors of two given numbers. Below is a demonstration of the same − Input val_1= 68 val_2= 34 Output The common divisors between the two numbers is4 Steps to find the common divisors ... 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. Problem Statement Write a Java program to sort an array of integers using the iterative quick sort method. Below is the demonstration of the same − Input {34, 76, 41, 32, 11, 0, 91, 102, -11} Output After iteratively performing quick sort, the array is -11 0 11 32 34 ... Read More
The Fibonacci Series generates subsequent numbers by adding two previous numbers. The Fibonacci series starts from two numbers − F0 & F1. The initial values of F0 & F1 can be taken as 0, 1, or 1, 1 respectively. Fn = Fn-1 + Fn-2 Problem Statement Write a program in Java program to print a Fibonacci series. Input Run the program Output 1 1 2 3 5 8 13 21 34 55 The above output is obtained when the values of n=10. Different approaches to print a Fibonacci series Following are the different approaches to printing a Fibonacci series − ... Read More
In this article, we will learn about constructors in Java. Constructors initialize objects when they are created. We will also see how the parent constructor is called in inheritance. Problem StatementWe will demonstrate possible approaches to show how the inherited constructor calls the parent constructor by default.Different approaches The following are the different approaches to show how the inherited constructor calls the parent constructor by default− Demonstrating inheritance properties ...

In this article, we calculate the number of minutes in a given duration using Java. The Duration class can perform time-based calculations like hours, minutes, days, etc.. and easily convert between these units. Using the toMinutes() method you will be able to get the number of minutes from a given Duration. Problem StatementGiven a Duration object representing a period of time, write a Java program to calculate the number of minutes in the specified duration.Input Duration = 25 days, 10 hoursOutput Minutes in 25 days = 36000Minutes in 10 hours = 600 Steps to get the number of ...

In this article, we use the System.nanoTime() method in Java to get the current value of the system timer in nanoseconds. It returns the current value of the most precise available system timer, in nanoseconds. Problem StatementGiven that you need to get the current value of the system timer in nanoseconds, write a Java program that retrieves this value using the System.nanoTime() method.Input There is no specific input as the program retrieves the system's current time in nanoseconds directly.Output Current Value: 49908709882168 nanoseconds Steps to get the current value of the system timer in nanosecondsThe following are the ...
