Separators in Java - Explained

 Separators in Java - Explained

By Naomi A.

Hello reader - Here, I am sharing the characters that are used as separators in Java, and explaining them for better understanding.

 __________________________________________________________________________________

What is a separator?

- A separator is a character or a sequence of characters that separates tokens in a program.

What is a token? 

- A token is a sequence of characters that are used to represent various elements of the code in a Java program - keywords, identifiers, literals, and punctuation.

Whitespace Is not considered a separator:

- Because Java is a free-form language, you don't need to abide by any indentation or spacing rules. Whitespace includes; spaces, tabs, and newline characters. 

- This improves readability for the developer but is ignored by the compiler.

Separators in Java:

Comma: 
The comma (,) is used to separate items in a list. For example: elements of an array or the arguments of a method.   
 
Semicolon: 
The semicolon (;) marks the end of a statement. 
 
Colon: 
The colon separator is used to create a constructor reference or method. 
 
Period:
The period (.) is used to access members of an object or class, such as fields and methods. 
Example: System.out.println("Hello World!")  
 
Forward Slash:
The forward slash (/) is used as the division operator and to create comments in Java code.
  
Curly Braces: 
Braces ({ and }) are used to enclose blocks of code, such as the body of a method or a loop.   
 
Square Brackets: 
Brackets ([ and ]) are used to access array elements and to specify the bounds of an array when declaring it.   It's important to use these separators correctly in your Java code, as they play a vital role in the structure and syntax of the language. 
 
Parentheses: 
Parentheses (() and ) are used to enclose the arguments of a method or the conditions of a loop or decision statement. They are also used to enclose expressions in certain contexts, such as when using the ternary operator or when casting a value.

Creating a Webpage - A Beginner's Guide (HTML, CSS, JavaScript) By Naomi A. Prerequisites: Before diving in, make sure you have access to a reliable text editor or integrated development environment (IDE) to create your HTML code. I personally recommend Visual Studio Code, an incredibly versatile tool that supports multiple programming languages. It's an excellent choice, especially for web development projects. Introduction: Welcome to this beginner-friendly demonstration of creating a simple web page using HTML, CSS, and JavaScript. In just 70 lines of code (with most of it dedicated to styling), you'll witness the possibilities that can be achieved! Please note that this is not an in-depth tutorial for HTML, CSS, or JavaScript. However, it serves as a great starting point for those who are curious about the potential of these languages. Here's a summary of what is covered here: The code starts with a document type declaration ( <!DOCTYPE html> ) specifying that

Teaching Computers to Play Tic Tac Toe: A Reinforcement Learning Approach by Naomi A.  You can see the full code on GitHub: https://github.com/SQLNoggin/Smart-TicTacToe-RL_NaomiA.git This Python script implements a reinforcement learning agent to play the game of Tic Tac Toe. The agent is trained through Q-learning, a type of model-free reinforcement learning that uses a Q-table to estimate the value of taking specific actions in particular states. Let's break down the key aspects:   Overview The script uses the Tkinter library to create a graphical user interface (GUI) where the Tic Tac Toe game can be played. NumPy is used for numerical operations, and the pickle library is used to save and load the Q-table to/from a file. Constant and Hyperparameter Definitions PLAYER_X and PLAYER_O : Constants representing the two players (1 for X and -1 for O). EMPTY : Constant representing an empty cell on the Tic Tac Toe board. ALPHA : The learning rate used in the Q-learning updates. GAMMA

Run Queries in SQL Server Using Python!

Run Queries in SQL Server Using Python! By Naomi A. This is a fairly quick one - all of the info needed on how the script works is in the comments! The full script is ready for download on GitHub: (LINK) # Import the pyodbc module. #This module allows Python to connect to an ODBC database, like SQL Server. import pyodbc # The variables hold the server name, database name, username, and password. # This is necessary in order to connect to the SQL Server database. server = 'ServerName' database = 'DBName' username = 'user' password = 'password' # Connection string: # This is a formatted string that the ODBC driver uses to know who is connecting (username and password), # where they are connecting to (server and database), # and what driver they are using to make the connection (ODBC Driver 17 for SQL Server). connection_string = f 'DRIVER= {{ ODBC Driver 17 for SQL Server }} ;SERVER= { server } ;DATABASE= { database } ;UID= { username } ;PWD
