Find Difference Between Sum of All Rows and All Columns in Java
In Java, a matrix can be represented using a two-dimensional array. Matrices are used for storing and manipulating data that have a tabular structure. Matrices have several properties and operations associated with them, such as addition, subtraction, multiplication, transposition, and determinant calculation. As per the problem statement we have to add sum of all individual rows and columns. Then we need to perform the difference between these added rows and columns and display the result. Let's start! For instance Suppose the original matrix is: {4, 2, 1}, {3, 5, 6}, {8, 9, 7} After performing ...
Read MoreGet Interior & Exterior Angle of Regular Polygon When Numbers of Sides of Polygon is Given in Java
A polygon is a 2-dimensional closed shape that has at least 3 sides. Depending on the number of sides, relationships of the sides and angles, and other characteristics, polygons can be classified under different names like triangles, squares, and quadrilaterals. An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon. Exterior angle is defined as the angle formed between a side of triangle and an adjacent side extending outward. In this article, we will find interior and exterior angle of regular polygon when numbers of sides of polygon is ...
Read MoreHow to Know the Separator for a Particular File System in Java
In Java, the file separator is a character that separates the components of a file path. The file separator varies depending on the operating system on which the Java program is running. On Windows systems, the file separator is backslash (\). On Unix-based systems (such as Linux and macOS), the file separator is forward slash (/). Let's start! For instance Suppose that we running the code on windows system After performing the operation to get the separator, the result will be: Separator for this file system is: \ Algorithm Step-1: Import the necessary libraries. ...
Read MoreHow to Know the File Store Type in Java?
In Java, the java.nio.file.FileStore class represents a storage pool, device, partition, volume, or other implementation-specific means of file storage. The FileStore class provides methods for querying information about the storage device, such as its total and available space, its file system type, and whether it supports certain features like file attributes or symbolic links. The type() method of the FileStore class returns a string representing the file store type. The file store type is a string that identifies the type of file system used by the file store. Examples of file system types include "NTFS" for the Windows NT ...
Read MoreHow to Know Where the Actual File is Getting Stored in Java?
In Java, you can use the File class to represent and manipulate file and directory paths. You can also use the File class to create, delete, and manipulate files and directories. To know where the actual file is getting stored in Java, you can use the getAbsolutePath() method of the File class. This method returns a string representation of the absolute path of the file, which includes the full path from the root directory to the file. Let's deep dive into the article to see where the actual file is getting saved in Java. For instance ...
Read MoreInteresting interview question on hashCode and equals method
One of the most interesting interview questions that I have encountered in my Java programming career is about the hashCode and equals methods. Interviewers always check whether the candidate knows equals() and hasCode() methods as they are the most important yet most confusing methods of the Java Object class. Both methods are used to check the equality of two or more objects. This article aims to provide some interesting interview questions related to hashCode() and equals() methods that will improve one's knowledge as well as skills. Java Interview Questions on hashCode() and equals() method When an interviewer starts questioning about ...

This is the reason why the demand for Java developers is still in the market. Being a Java developer, one might be interested in learning some cool tricks that can make the code more elegant, efficient and fun. In this article, we are going to share some useful tricks that we can use ...
Read MoreIs there any equivalent to typedef of C/C++ in Java?
We can find many similarities between Java and C/C++ programming languages in terms of syntaxes and features. But, there are several functionalities that have been omitted from Java like 'typedef'. If someone coming from a C/C++ background, must have heard the 'typedef' keyword, and often wonders, is there any equivalent to typedef in Java? In simple words, Java does not provide a direct equivalent to typedef. The creators of Java replaced this feature with classes. In fact, a class can do even more than a typedef can do. Replacement to typedef of C/C++ in Java? Before exploring the ...
Read MoreWhat is Iterable Interface in Java?
In simple words, the iterable interface is a common interface that allows us to iterate over a collection of objects. It was first introduced with the release of JDK 1.5 and made available in 'java.lang' package. The Java Collection Framework extends this interface, hence all the classes available in this collection framework by default implement the iterable interface. In other words, the classes of collection framework such as ArrayList, TreeSet, TreeMap and HashMap are iterable. This article aims to explain the iterable interface of Java along with its use case. Iterable Interface in Java The only use case exhibited ...
Read MoreWhat is Interface Naming Conflicts in Java?
In Java, interfaces serve two purposes pure abstraction and multiple inheritance. Generally, an interface consists of abstract methods and variables that define the behavior which a class can implement. If we create two interfaces that contain methods and variables with the same name, then interface naming conflicts may arise. However, it is not the only scenario that can cause this conflict, we are going to explore all the possible situations causing interface naming conflicts. Interface Naming Conflicts in Java Before heading to the interface naming conflicts, it is necessary to understand the abstract methods and how to create interfaces in ...
