In this article, we will see what are the possibilities available to create thread-safe HashSet instances and see what will be equivalent to ConcurrentHashMap for HashSet. We will also look at the benefits and drawbacks of each approach. Before JDK8 we are not able to create a Thread Safe ConcurrentHashMap because java.util.concurrent package in JDK8 does not provide a class named ConcurrentHashSet, two new methods were added that are discussed below. ConcurrentHashMap is the Map implementation that allows us to modify the Map while iterating. The ConcurrentHashMap operations are thread-safe. ConcurrentHashMap doesn't allow null for keys and values. Ways to ... Read More
In this problem statement we have to move all the files in the folder with the name of creation and modification date directory with the help of Python. In this task we will use some predefined libraries of Python for smooth processing of relocating the files. Understanding the Problem As we have seen, managing the files as per the date or modification and creation time. So here in this article we will simplify this task by creating the Python script to move the files as per the creation and modification dates by giving the folder name as the modification or ...

In this article, we will understand how the iconphoto() method is used set icons for the GUI application window created using tkinter. Understanding the iconphoto() Method The iconphoto() method in the tkinter is used to set icons for the tkinter window. Usually, the icon of the application is visible on the application title bar, taskbar, and ... Read More
In this article we will learn how to modify equal tuple rows with the help of Python programming. Whenever we talk about data, sometimes we need to modify that data also. So here we will modify equal tuple rows data as per the equality of the records. Understanding the Problem The problem at hand is to modify the given tuple for equal rows using python. So we will be having a list of tuples and our task is to modify as per the condition for the particular tuple row in the given list. Let's see the usage of the following ... Read More
The files are very important documents in our systems. In files we store our important data and moving these files is also an important task to organize the system. So we will learn how to move and also overwrite the files and folders using Python modules. Understanding the Logic for the Problem The problem at hand is that we have to create a code for moving and overwriting the files and folders in Python. For solving this problem we will import os and shutil libraries of Python. So with the help of these libraries we can move and overwrite the ... Read More
Hypertext markup language i.e. HTML is a markup language that is used to create webpages content on the internet. HTML document files may contain some unwanted or malicious elements which can cause several issues while rendering the webpage. Before processing the HTML content we need to perform HTML cleaning for removal and cleaning of the malicious elements in the file. HTML entities are special characters that need to be converted into corresponding HTML representations to ensure proper rendering in browsers. In this article, we will understand cleaning and entity conversion methods using Python. HTML Cleaning HTML cleaning is done ... Read More
Two lists of lists can be merged in Python using the zip() function. Combining two lists of lists can be particularly valuable when dealing with tabular or multidimensional data, as it allows for combining related information from different sources. The zip() function, a powerful built-in tool in Python, facilitates this process by pairing corresponding elements from the sublists and generating a new list. In this article, we will explore how to zip two lists of lists in Python using the zip() function. Algorithm A general algorithm to zip two lists of lists is as follows: Create two lists ...

The problem statement requires finding the summation of nested record values using Python. Sometimes we are required to add the values present in the data so that time this approach can be useful as record is the powerful dataset in terms of updating or manipulating the data using the keys. Understanding the Problem The given problem is to find the addition of values in the given record so here we will be using the nested dictionary as a record. And we will implement the code using Python. And the nested dictionaries are the dictionary inside the dictionary. And we have ... Read More
