In JDBC (Java Database Connectivity), the ResultSet interface represents the result set of a database query in Java. One of the important methods provided by ResultSet is getType(), which returns the type of the ResultSet object. Result getType() method The getType() method is used to determine the type of cursor and its behavior when scrolling through the result set.Syntax of getType() int resultSet_Type = rs.getType(); This method returns an integer value that corresponds to one of the ResultSet type constants. These constants indicate the type of cursor used by the ResultSet: ResultSet.TYPE_FORWARD_ONLY (value: 1003): This ... Read More
In this article, we will learn to convert an array of objects into an object of arrays in JavaScript. When working with JavaScript, it's common to handle arrays of objects representing structured data. A frequent challenge is grouping these objects based on a shared property and transforming the result into a new data structure. Problem Statement The goal is to convert an array of objects into an object of arrays where the keys represent a specific property (e.g., roles) and the values are arrays of corresponding data (e.g., player names). Input const team = [ { role: ... Read More
The union of two sets combines all the unique elements from both sets into one. In Java we can achieve this using the HashSet class, which ensures no duplicate elements. This article will demonstrate two approaches to finding the union of two sets. Different Approaches Following are the two different approaches to getting the union of two sets in Java − Using the addAll() Method Using Streams Using the addAll() Method The simplest way to find the union of two sets is by using the addAll() method of the HashSet class. This ... Read More
In this article, we will learn to convert a binary number into a decimal number in Java.Binary numbers are fundamental in computer science and digital electronics, where data is represented in a base-2 numeral system consisting of only 0s and 1s. Converting binary numbers to their decimal equivalents is a common task. Problem Statement The task is to convert a binary number into its decimal equivalent using Java. − Input 1110 Output 14 Different Approaches Following are the two different approaches to converting a binary number into a decimal number in Java − Using ...

In HTML date picker is a useful concept as it enables people to select a specific date on a website or even a form. By default, date pickers accept any date to be entered, however, if a user wishes to limit the range of dates that are selectable—say from the past until today. What is a Date Picker? A date picker is a form of user interface component that enables users to select dates through a calendar or clock. Most usually it is used in forms when a date has to be entered for example in reservation systems, scheduling software, ... Read More

To hide scrollbar using CSS, we will understand different approaches. Scrollbars are one of the core components of web browsers where users navigate in a content area wider than a viewable window. In this article, we have discussed three approaches for hiding the scroll bars using CSS and when each might be useful. We can hide the scrollbar in below mentioned directions − Hiding the Vertical Scrollbar Hiding the Horizontal Scrollbar Hiding Scrollbars in Both Directions 1. Hiding the Vertical Scrollbar In this case, we disable the vertical bar but enable the vertical scrolling of the page ... Read More
To separate header from body in HTML, can be useful in providing information and highlighting the actual body. The header includes elements such as the title of the web page, the list of navigation options, and other initiating features. The content section contains webpage information and is usually positioned at the bottom of the webpage. In this article we are having a web page with the header and the main body. Our task is to separate header from body in HTML. Approaches to Separate Header from Body Using Semantic Tags Using CSS Using Multiple Headers 1. Using Semantic ... Read More
A B-tree is a self-balancing tree in data structures that allows efficient storage of sorted data. Each node can hold multiple keys and have many child nodes. B-trees are versatile data structures that can efficiently handle large amounts of data. However, traditional binary search trees become inefficient for storing and searching large datasets due to their lower performance and high memory usage. B-trees, balanced trees, are self-balancing trees designed to overcome these limitations. B-trees are characterized by the large number of keys that can be stored in a single node, often called "large key" trees. Each node in a ... Read More
In Python, to open a binary file in append mode, we can use the open() function with the mode set to ab. This allows us to open an existing file or create a new one. Using the open() function with the appropriate mode enables us to work with the file as needed. Mode 'ab' In the mode 'ab', the 'a' stands for append mode, which allows us to add new data to the end of the file without truncating its existing content. The 'b' stands for binary mode, used when handling files containing non-text data or non-readable characters. Binary files ... Read More
