Non-blocking Server Java NIO (New Input/Output) is a very powerful networking and file-handling application that functions as an alternative to Java's standard IO API. Due to the addition of more sophisticated features since JDK 4's introduction, it has quickly emerged as the preferred I/O system among numerous engineers. The improved support it offers for file handling and file system features is one of the features that distinguish Java NIO. Since the NIO file classes have such incredible capabilities, it is extensively used in file handling. If you look closely, you'll notice that java.nio package specifies the buffer classes employed by ... Read More

A matrix is a two-dimensional array of many numbers arranged in rows and columns. And it is called as m X n matrix where m and n are the dimensions. In general, the multiplication of two matrices can be possible only if the number of columns in the first matrix is equal to the number of rows in the second matrix. Input Output Scenarios Assuming we have two input matrices A and B having 3X3 rows and columns. Then the resultant matrix will also have 3 rows and 3 column. [a, b, c] [j, k, l] [(a*j+b*m+c*p), (a*k+b*n+c*q), (a*l+b*o+c*r)] [d, ... Read More

Overview of Node.js vs Java Java has been a long-standing favorite for programmers worldwide, while Node.js is a relatively new JavaScript runtime environment. This article delves into the differences between Node.js and Java and aims to provide a better understanding of both tools and their respective applications. While we may never settle the question of which is ultimately better, gaining insight into these powerful tools can help us make informed decisions about where and when to use them. What Is Node.js? In 2009, Ryan Dahl created Node.js, a cross-platform JavaScript (JS) runtime environment that enables developers to use JavaScript on ... Read More

A matrix is defined as a set of numbers arranged in rows and columns. A matrix with m rows and n columns is called an m X n matrix and m and n are called its dimensions. A matrix is a two dimensional array, which is created by using lists or NumPy arrays in python. The Trace of a Matrix The trace of a matrix is defined as the sum of its diagonal elements (i.e, elements from upper left to lower right ). Calculating the Trace of a matrix can be possible only for a square matrix (i.e., the matrix ... Read More

Overview of Object Model Have you ever thought about how software programs can see and communicate with the components that make them up? The object model is useful in this situation. Developers can represent those components as objects using sophisticated object-oriented techniques thanks to a strong system or interface. The object model is actually so crucial to software development that it's frequently one of the first stages. The object model establishes the framework for a reliable, adaptable, and scalable application design by defining crucial features like inheritance and encapsulation. Are you set to learn more about object-oriented programming? Objects and ... Read More

Numbers in Java It's important to understand that the number class isn't a tangible class, but rather an abstract one. Inside it, we have a set of wrapper classes that define its functions. These wrapper classes include Integer, Byte, Double, Short, Float, and Long. You may notice that these are the same primitive data types we previously discussed, but they're represented as individual classes with capitalized names in keeping with class naming conventions. The compiler automatically converts primitive data types into objects and vice versa, based on the requirements of a particular function or program scope, and the number class ... Read More

A matrix is a set of numbers arranged in rows and columns. A matrix with m rows and n columns is called an m X n matrix and m and n are called its dimensions. A matrix is a two dimensional array, which is created by using lists or NumPy arrays in python. In general, Matrix multiplication can be done by multiplying the rows of the first matrix by the column of the second matrix. Here, the number of columns of the first matrix should be equal to the number of rows of the second matrix. Input Output Scenarios Assuming ... Read More

A matrix is a two-dimensional array of many numbers arranged in rows and columns. The addition of two matrices is a process of adding corresponding elements of two matrices and placing the sum in corresponding position of the resultant matrix. And this can be possible, only if both the matrices have an equal number of rows and columns. In Python multidimensional arrays are created by using lists or NumPy arrays. The list data structure can accept lists as elements so that we can easily create matrice. Also, the Numpy module provides numerous methods to work with multidimensional arrays. ... Read More

The diagonals are nothing but crosswise elements of a matrix. A square matrix has two diagonals. One is the Primary diagonal - located from the top left corner to the bottom right corner of a square matrix. And the second one is the Secondary diagonal - located from the top right to the bottom left corner. Interchange the diagonals is nothing but changing the primary and secondary diagonal elements of a matrix. See the below scenarios to understand it briefly Input Output Scenarios Assume we have a square matrix. And output matrix will be the resultant matrix ... Read More

A matrix is a two-dimensional array of many numbers arranged in rows and columns form. Python does not have any data type to represent a matrix, but we can use a nested list or NumPy array as a matrix. See the below input output scenarios to understand how to interchange the first and last column elements of a matrix. Input Output Scenarios Assume we have a 3X3 matrix represented using a list of lists. And output matrix will be the resultant matrix whose first and last column elements are interchanged. Input matrix: [1, 3, 4] [4, 5, 6] [7, ... Read More
