To set a Date object to noon to the closest possible millisecond of the day, we will make sure that the hour is set to noon, and both the minutes, seconds, and milliseconds are set to zero. This precise setting can be achieved using the Calendar class in Java. By setting these specific fields, we can ensure that the time is 12:00:00.000 PM, providing the closest possible millisecond representation of noon. Returning a date set to noon to the closest possible millisecond of the day in Java is quite easy. Let's learn the following ways: ... Read More
To create a character array from a string object, we convert each character of the string into elements of an array of type char. This is useful when we need to manipulate or access individual characters within the string. String Object: A string object is an instance of the String class representing a sequence of characters. It is immutable, which means once it is created, its value cannot be changed. Character Array: A character array is a data structure in Java that stores a sequence of characters. Creating Character Arrays from ... Read More
To get the ID of the current timezone in Java, we use the ZoneId class that belongs to java.time package. This provides a way to work with different timezones and their IDs. In Java, the ZoneId class represents a time zone identifier, such as India/Europe. The ZoneId can be used to retrieve the unique ID of the current timezone. To Get the ID of this timezone in Java is quite easy. Let's learn the following methods: Using Zone Id Class Using Zone Id.systemDefault() Using TimeZone.getDefault().toZoneId() Using ... Read More
To display both horizontal and vertical grid lines in a table, use the setShowGrid() method and set it to true − The setShowGrid() method is used in graphical user interfaces or data visualization tools to control the visibility of grid lines in a component, like a chart or a table. table.setShowGrid(true); JTable is a class in the Java Swing library, part of the JFC(Java Foundation Classes). It creates and manages tables in a GUI(graphical user interface) application. Syntax void setShowGrid(boolean showGrid) Parameter showGrid: A boolean that determines grid line visibility for both horizontal and vertical lines is true ... Read More
In this article, we will learn to count the number of undefined elements in an array using JavaScript. When working with arrays in JavaScript, you may encounter situations where certain elements are either explicitly set as undefined or are missing altogether (often represented by empty slots in sparse arrays). Problem Statement Given an array that may contain undefined values, we need to count how many elements in the array are defined (i.e., not undefined). Input const arr = [12, undefined, "blabla", , true, 44]; Output 44 elements are defined (12, "blabla", true, and 44). Thus, the expected output is ... Read More
In this article, we will learn the JavaScript equivalent of Python's zip Function In Python, the zip() function is a convenient way to combine multiple tables into a single iterable of tuples. However, JavaScript does not have a built-in equivalent for this functionality Problem Statement Given two or more arrays of equal length, implement a function in JavaScript that combines these arrays into a single variety of arrays, where each inner array contains the elements from the input arrays at the corresponding positions. Input arr1 = [1, 2, 3], arr2 = ['a', 'b', 'c']Output [[1, 'a'], [2, 'b'], [3, 'c']] ... Read More
In this article, we will learn how to iterate through all DOM elements on a webpage using JavaScript. By doing so, we can easily access and manipulate various elements of the page, whether for debugging, gathering information, or applying changes to the page's structure and content. We'll walk through a step-by-step process to loop through all elements and display the results in the console, helping you better understand how to interact with the DOM. What is the DOM? The Document Object Model (DOM) is a representation of the structure of a webpage. It treats each part of the webpage (HTML ... Read More
To check if a string can be formed from another string by at most X circular clockwise shifts, we can calculate the difference of ASCII value of the characters and then compare it with the X. Circular clockwise shifts for the string mean rotating the characters of the string to their next character in alphabetic order. In this article, we are given with a string, target and a number which represent the number of circular shifts to be made. Our task is to write a JavaScript program to check if the target can be formed from the string by at ... Read More
To cyclically rotate an array by one means shifting the value present at each index to their left or right by one. In this article, we are having an array and our task is to write a JavaScript program to cyclically rotate an array by one. Users must be familiar with JavaScript loops and array operations. Example Input: arr= [ 1, 2, 3, 4, 5, 6 ] Output: Left rotation: [ 2, 3, 4, 5, 6, 1 ] Right rotation: [ 6, 1, 2, 3, 4, 5 ] Approaches to Cyclically ... Read More
