In few scenarios, we need to change the extension of a file programmatically such as renaming a .txt file to .md or converting .csv to .json. Python provides different ways to do this using the os and pathlib modules. In this article, we’ll explore how to change a file’s extension using both approaches. Using os.path.splitext() The os.path.splitext() method of the os module in Python is used to split the file name into the name and extension. We can use this method to strip off the old extension and add the new extension. Example In this example, we are using the os.path.splitext() ... Read More

The class Component is the abstract base class for the non-menu user-interface controls of AWT. A component represents an object with graphical representation. The class Container is the superclass for the containers of AWT. The container object can contain other AWT components.

All instance methods in Java are virtual except, static methods and private methods.

XML is abbrivated as Extensible Markup Language which is used format to represent a structured data. It's is useful when we are exchanging information between two systems. In Python, the xml.etree.ElementTree module helps us to read and work with XML data. In this article, we will explore how to extract specific parts of an XML file using this library. Introduction to XML and ElementTree When we are working with XML files in Python, the xml.etree.ElementTree module is used for parsing and navigating XML structures. It reads an XML document and builds a tree of elements from it by allowing us ... Read More

The java.util.Locale class object represents a specific geographical, political, or cultural region. An operation that requires a Locale to perform its task is called locale-sensitive and uses the Locale to form information for the user. The locale is a mechanism for identifying objects, not a container for the objects themselves.

The Python shutil module provides a number of functions for high-level operations on individual files and file collections. In this article, we will go through different methods of moving a file from one folder to another using Python. Using the OS Module The Python OS module gives users the ability to create interactions with their operating systems. Using shutil.move() method Following is an example which shows how to move a file from one folder to another using shutil.move() method - # importing the modules import shutil import os # Providing the folder path origin = 'C:\Users\Lenovo\Downloads\Works' target = 'C:\Users\Lenovo\Downloads\Work ...

System class belongs to the package java.lang. It cannot be instantiated. A System class provides − standard output. error output streams. standard input and access to externally defined properties and environment variables. A utility method for quickly copying a portion of an array. a means of loading files and libraries. Following are the fields for java.lang.System class − static PrintStream err − This is the "standard" error output stream. static InputStream in − This is the "standard" input stream. static PrintStream out − This is the "standard" output stream.

When we are working with files in Python we may need to copy only a certain type of file. Python makes this task simple and flexible by using built-in modules such as os and shutil and pathlib. Copying specific files using shutil and os modules When we want to copy only certain files such as all .txt files from one folder to another in Python then we can use the shutil and os modules. The shutil module is used to perform high-level operations on files such as file copying, moving, archiving and removing directories whereas os module is used to ... Read More

The Callable interface is found in the package java.util.concurrent. The Callable object can return the computed result done by a thread in contrast to a runnable interface which can only run the thread. The Callable object returns a Future object which provides methods to monitor the progress of a task being executed by a thread. The future object can be used to check the status of a Callable and then retrieve the result from the Callable once the thread is done. It also provides timeout functionality.

We can easily check the Odd or Even by using conditional statements. We can divide the number by 2, then check whether the remainder is 0 or not. If 0, then it is even. We can also perform the AND operation with the number and 1. If the answer is 0, then it is even; otherwise odd. There is no need to use conditional statements in both approaches. We will see two different methods to check the odd or even. Using Modulo Operator This approach uses the Modulo Operator ... Read More
