The nextDouble() is a method of Java Scanner class which is used to scan the next token of the input as a double.

If you're working with numbers in Java, you'll often need to convert input from one format to another. The nextDouble() method of the Java Scanner class allows you to do just that, scanning the next token of the input as a double.

This can be particularly useful when reading in data from a file or user input. For example, if you're reading in a list of prices from a file, you can use nextDouble() to convert them to double values for use in your program.

If the next token cannot be converted to a double, nextDouble() will throw an InputMismatchException. So be sure to check for this before calling the method.

Here's a quick example of nextDouble() in action:

Scanner scanner = new Scanner(System.in);

System.out.print("Enter a price: ");

double price = scanner.nextDouble();

System.out.println("The price is: " + price);

As you can see, nextDouble() makes it easy to convert input to the double format. Give it a try in your own programs and see how it can help you streamline your data processing.
