Java Language is one of the most used popular object - oriented programming language in present world. Class concept is one of the most important feature in Object - oriented languages. A Class is a like a blue print of an object. For example, when we want to build a house we first create a blue print of the house in other words we create a plan showing how we are going to build the house. Based on the plan we can create a number of houses. Similarly using class, we can create a number of objects. A class ... Read More

In this section, we are going to write a Java program to find maximum odd number in an Array using Stream and Filter. Odd numbers are the numbers which cannot be divided by 2 or these numbers give remainder as 1 when they are divided by 2. In other terms which can be written in the form of 2n+1. We will find the maximum odd number in the array. Problem Statement Write a program in Java to find maximum odd number in array using stream and filter − Input array = {1, 7, 2, 3, 9, ... Read More

The reciprocals of an arithmetic series without considering 0 is known as Harmonic series. If $a_{1}, a_{2}, a_{3}$… is arithmetic series then $\frac{1}{a1}$, $\frac{1}{a2}$, $\frac{1}{a3}$, … is the harmonic series. In this article, we will discuss how to implement a Java program to find the harmonic series. Harmonic Series For 1st term n = 1 and for every term n is incremented by 1 and at last the nth term the value is ‘n’. Harmonic series : $1+\frac{1}{2}+\frac{1}{3}$.......+$\frac{1}{n}$ Where, 1/n is the nth term of harmonic series. Problem Statement Write a Java program to find the ... Read More

Euclid’s Algorithm is an efficient algorithm which helps us to find G.C.D and L.C.M of two numbers. In this article, we are learning to write a Java program to find the G.C.D and L.C.M of two numbers using Euclid’s Algorithm. G.C.D. of two numbers G. C. D, known as Greatest Common Divisor is the highest common factor that divides the two given numbers exactly. Now let us look into an example and calculate the G.C.D of a two numbers. Factors − In mathematics, Factors are the numbers that can divide a given number. Ex − 8 can be divided ... Read More

Chromatic Index of a graph is the parameter which indicates the minimum number of colours needed to colour all the edges of graph such that no two edges sharing the common vertex have same coloured edge. In this article, we will discuss how to find the chromatic index of cyclic graphs using the Java programming language. What is a Cyclic Graph? Cyclic Graph is a graph which consists of at least one cycle path in that particular graph. Cyclic path is a path that starts from a specific node and ends at the same node. What is Graph Colouring? ... Read More

We can use different approaches in Java to Find Common Elements between two arrays. We will discuss the approaches, including the basic steps involved, and provide the necessary code to achieve our goal. Whether you are a beginner or an experienced Java programmer, this article will provide you with the tools and knowledge necessary to solve this common programming problem. In this article, we will learn different ways of finding the common elements between two arrays. Examples for Common Elements Between Two Arrays: Example 1: Input: array1 = {4, 2, 3, 1, 6} array2 = {6, 7, 9, ... Read More

The cube root of a number is an integer value when multiplied by itself thrice, giving the original number. In this article, we are going to write a Java program to find the cube root of a number using binary search. Finding the cube root of a number is one of the applications of the binary search algorithm. We will discuss in detail how we calculate the cube root using a binary search algorithm in Java. Problem Statement Write a Java program to find the cube root of a number using Binary Search − Input 1 64 Output 1 4 ... Read More

We can calculate the area of the circle in Java using Method Overloading. “Method Overloading” is a feature in Java that allows one to write more than one method in the same class using the same method name. It will enable us to declare more than one method with the same names but with different signatures i.e., the number of parameters in the method may be different or the datatype of parameters may be different. Now, let us achieve Method Overloading in Java by considering the “area of a circle” as an example. Before moving to an example, now ... Read More

Venn diagrams are diagrams used to represent the relationships between sets. To create Venn diagrams, we are going to use matplotlib. Matplotlib is a popular data visualization library used in Python to create interactive plots and charts. It is also used to make interactive figures and diagrams. Matplotlib provides a number of functions to customize plots and diagrams. In this tutorial, we will illustrate three examples to customize Venn diagrams. Example Here’s a simple example that creates an intersection of two Venn diagrams; first, we imported necessary libraries and imported venns. Then we created data sets as Python ... Read More

An ogive graph graphically represents the cumulative distribution function (CDF) of a set of data, sometimes referred to as a cumulative frequency curve. It is applied to examine data distribution and spot patterns and trends. Matplotlib, Pandas, and Numpy are just a few of the libraries and tools offered by Python to create ogive graphs. In this tutorial, we'll look at how to use Matplotlib to generate an ogive graph in Python. To create an ogive graph, we need to import the required libraries. In this example, we will use Matplotlib, Pandas, and Numpy. Matplotlib is a popular data visualization ... Read More
