Final answer:
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:
- Open the input file using Scanner.
- Read the quantity and type of coins line by line.
- Parse the information into usable data.
- Calculate the total value by multiplying the quantities by their respective coin values.
- Open an output file using a FileWriter.
- 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.
