Are there also doubles in Java?

Hey there! Great question, and it's a common one when starting with Java!

Yes, Java does indeed have a type called double. Here's a straightforward explanation:

Types of Numbers in Java:

1. Integers:

2. Whole numbers without decimals (e.g., 5, -11, 0).

3. Floating-Point Numbers:

4. Allow representation of numbers with decimals.
5. There are two types in Java:
   • Float: Uses 4 bytes (single precision)
   • Double: Uses 8 bytes (double precision)

So, what is a double? - double is a data type used for floating-point numbers with double precision. - It can handle larger numbers and provide more precision than float. - Here's how you might use it:

public class Main {
    public static void main(String[] args) {
        double myDouble = 3.14159;
        System.out.println(myDouble);  // This will print: 3.14159
    }
}

In your lesson, when you refer to floating-point numbers, it's often using the double type due to its precision and flexibility.

Feel free to try running the example above, and let me know if you have any questions or need more clarity! Happy coding! 🌟
