Command-Line Arguments in Java #javaprogramming #shortsviral #shortsviralvideo #techcode #viral

Command-line arguments in Java allow you to pass data to your program when you start it from the terminal.
How It Works: -
args Parameter: The args parameter in the main method is an array of String objects. Each element in the array represents a command-line argument.
Checking for Arguments: The program first checks if any arguments were passed by checking the length of the args array.
Iterating Over Arguments: If there are arguments, it iterates over the args array and prints each argument.
Running the Program: -
To run the program with command-line arguments, follow these steps:
Compile the Program: Open your terminal and navigate to the directory where your Java file is located. Compile the program using javac:
Run the Program with Arguments: Pass the arguments when you run the program using java:

Practical Use Case: -
Command-line arguments are useful when you need to provide configuration parameters or input data to your program without hardcoding them. They make your programs more flexible and easier to use in different environments.
