What Is Application Programming Interface. API is the acronym for Application Programming Interface, API is a set of defined rules that explain how computers or applications communicate with one another. APIs implemented between application and web server, acting as an intermediary layer that processes data transfer between systems. Types of API’s They are four main types of API’s Open APIs− Open-source application programming interfaces Also known as Public API, there are no restrictions to access these types of APIs because they are publicly available. Open APIs can been can been access by any developer. Partner APIs− This API exposed ... Read More
Anonymous object in Java means creating an object without any reference variable. Generally, when creating an object in Java, you need to assign a name to the object. But the anonymous object in Java allows you to create an object without any name assigned to that object. So, if you want to create only one object in a class, then the anonymous object would be a good approach. Reading this article, you will learn what an anonymous object is and how to create and use anonymous objects in Java. Let's get started! Anonymous Object in Java Anonymous means Nameless. An ...

Have you ever faced the situation of extending a string or char array? If you haven't yet, you might probably encounter this situation in the future. It is a common practice to append a single character to a string or char array in Java. The significant difference between a string array and a char array is that a string array is a sequence of characters, and a char array is a sequence of collection of data type char. String array runs as a single entity, whereas char array runs as a separate entity. In this blog, we will look ... Read More
This tutorial will discuss how to write a Swift program to find the cosine of given radian value. A cosine function is used to define the ratio of the length of the adjacent side to the hypotenuse in the right-angled triangle. It is also known as the cos function. The mathematical representation of the cosine() function is − cos() = adjacent Side/ hypotenuse In Swift, we can calculate the cosine of the given radian value using the pre-defined cos() function. This function return the cosine value of the specified number between -1 to 1. Here, the specified number represent ... Read More
This tutorial will discuss how to write a Swift program to find the sine of given radian value. A sine function is used to define the ratio of the length of the opposite side to the hypotenuse in the right-angled triangle. It is also known as the sin function. The mathematical representation of the sine() function is: sin() = opposite Side/ hypotenuse In Swift, we can calculate the sine of the given radian value using the pre-defined sin() function. This function return the sine value of the specified number between -1 to 1. Here, the specified number represents an ... Read More
This tutorial will discuss how to write a Swift program to calculate the volume and area of the Sphere. A sphere is a three-dimensional round solid shape or object. Or we can say a sphere is a shape that is defined in three axes: x-axis, y-axis, and z-axis. It does not hold any vertices or edges. Volume of the Sphere The amount of space occupied by a sphere in the three-dimensional plane is known as the volume of a sphere. For example, we want to fill a spherical ball with liquid, so using volume we can calculate the required ... Read More
This tutorial will discuss how to write a Swift program to calculate the volume and area of the cylinder. A cylinder is a three-dimensional shape that has two identical parallel circular bases joined by a curved surface.Volume of the Cylinder The amount of space occupied by the cylinder in the three-dimensional plane is known as the volume of the cylinder. For example, we want to fill a cylindrical bottle with shampoo, so using volume we can calculate the required amount of shampoo. We can calculate the volume of the cylinder using radius and height of the cylinder. Formula Following is ... Read More
This tutorial will discuss how to write a Swift program to find the sum of first N odd numbers.A number that is not divisible by 2 or we can say that when an odd number is divided by 2 then it leaves some remainder such type of number is known as an odd number. For example, when 2 divides by 2 leave remainder 0 whereas 3 divides by 2 leaves remainder 1. So it means 2 is even number and 3 is an odd number. List of odd numbers is: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, ... Read More
This tutorial will discuss how to write a Swift program to find the sum of all odd numbers upto N. A number that is not divisible by 2 or we can say that when an odd number is divided by 2 then it leaves some remainder such type of number is known as an odd number. For example, when 2 divides by 2 leave remainder 0 whereas 3 divides by 2 leaves remainder 1. So it means 2 is an even number and 3 is an odd number. List of odd numbers is − 1, 3, 5, 7, 9, 11, ...
