Should I use the “var” keyword when declaring local variables or I should go the old ways thus data type [identifier]? And also how will it affect my program if I use the var keyword. I will be glad if someone let me know the right one 🙏❤️.

Using the "var" keyword when declaring local variables in Java is a matter of personal preference and coding style. The "var" keyword was introduced in Java 10 as a way to reduce boilerplate code and improve readability by allowing the compiler to infer the data type of the variable based on the value assigned to it.

When you use the "var" keyword, you are essentially telling the compiler to determine the data type for you, which can make your code more concise and easier to maintain. However, some developers prefer to explicitly declare the data type of their variables using traditional syntax [data type identifier] for clarity and readability.

In terms of how it will affect your program, using the "var" keyword does not have any impact on performance or functionality. The choice between using "var" or explicitly declaring data types is mainly a matter of personal preference and coding style. It's important to note that while using "var" can make your code more concise, it's also important to ensure that your code remains clear and easy to understand for other developers who may be working on it in the future.

we already answered, but it doesnt affect the program, should compile the same other than polymorphic casts like Animal dog = new Dog() versus var dog = new Dog() var is specifically Dog
