Question

Create a Scanner in Java that reads a file indicating the quantity and type of coins, then writes to another file the total monetary value. Test it with the given examples.

Answer 1

The question pertains to creating a Java Scanner to read a file containing coin quantities and types and calculate the total value, then writing this to another file. It is a High School level Computers and Technology task, involving file handling and basic arithmetic operations in Java.

Step-by-step explanation:

The subject of the question involves creating a Scanner in Java to read and write files, specifically to calculate the total monetary value of coins given a file input. This question falls under the category of Computers and Technology, and typically would be a task assigned in a High School grade level computer science or programming class. To solve this problem, you would need to know how to read from a file using a Scanner object, perform calculations in Java, and output to a file using a FileWriter or similar object.

An example solution would involve the following steps:

1. Open the input file using Scanner.
2. Read the quantity and type of coins line by line.
3. Parse the information into usable data.
4. Calculate the total value by multiplying the quantities by their respective coin values.
5. Open an output file using a FileWriter.
6. Write the total monetary value to the file.

Testing the program with given examples means running the program with provided input to ensure it reads, calculates, and writes correctly.
