Java programming involves the conversion of String to byte array, a handy technique for a multitude of purposes including network communication or data encryption. To achieve this, the String class provides an array of methods for such conversion, with the getBytes() method being one of them. It is crucial to note that choosing the appropriate encoding is crucial since each encoding utilizes different regulations when it comes to character to byte value mapping. In this article, we will delve into two techniques for converting a String to a byte array using Java's getBytes() method. Additionally, we will provide an ... Read More

In MATLAB, the variables are typically stored in the form of a matrix or array. Sometimes, we require a matrix or array of zeros to perform a specific operation. Therefore, MATLAB allows us to create a matrix or array of zeros. For this task, we can use MATLAB's built-in functions or manual methods. In this article, we will learn different methods to create a matrix or array of zero with the help of example programs in MATLAB programming. Array of Zeros using `zeros()` Function in MATLAB MATLAB provides a built-in function named `zeros()` to create a matrix ... Read More

Traversing a directory, a common task in various programming applications, involves navigating through the files and subdirectories in a folder. In Java, there exist different strategies for directory traversal, with recursion and iteration employing a stack being two common approaches. Recursion necessitates a function repeatedly calling itself to solve a problem, whereas iteration utilizing a stack requires a data structure to track the program's state. Both methods possess their own advantages and disadvantages, and the optimal approach hinges on the particular needs of the program. This article delves into both methods, presenting sample code to exemplify their use in Java. ... Read More

MATLAB provides an integrated app building toolbox that we can use to create a graphical user interface based app without writing any kind of code. Hence, MATLAB allows users to create professional applications by just drag and drop facility. After that the user can write a MATLAB code to define the behavior of the app options. As mentioned above, this article is primarily meant for creating a user interface in the application which provides a list of options from which a user can select any number of choices. This user interface is referred to as checkbox. A checkbox ... Read More

Recursion, a potent programming technique, entails the resolution of a problem by decomposing it into smaller, more manageable sub problems and applying the same algorithm to solve them. In the realm of Java programming, recursion proves to be an invaluable tool when it comes to printing the binary representation of an integer. The binary equivalent, expressed in a base-2 numeral system that employs only two digits, 0 and 1, poses a common challenge in the field. In this article, we shall embark to unravel the intricacies of printing the binary equivalent of an integer using recursion in Java. Our ... Read More

The XSLT (eXtensible Stylesheet Language Transformations) Processor is a piece of software that processes XML documents and applies transformation rules to create new XML documents or other output formats like HTML, plain text, or PDF. With the use of templates, element selection and manipulation, and operations like sorting and filtering, developers can build rules for converting XML documents into various formats using the powerful language known as XSLT. An XSL processor that can be used to implement XSLT transformations is built into the popular programming language Java for processing XML documents. Developers can read, parse, and process XML documents, apply ... Read More

MATLAB allows us to combine two images through various methods like image fusion, image join, image concatenate, image overlay, image blending, etc. In this tutorial, we will explore all these techniques of combining two images. Combine Two Image in MATLAB using `imtile()` Function In MATLAB, we can combine two images by using the `imtile()` function. This function allows us to arrange our multiple images in a tiled layout. Syntax To combine two images, the `imtile` function takes the following syntax: img = imtile({img1, img2}, 'GridSize', [1, 2]); Now, let us see the implementation of the ... Read More
