Good day! I was writing a code that will compute the salary of each employee on our school depending on their position using a FileReader(File Handling). I only managed to do this code and don't know how to start again

can someone give me an idea of what should I do?

Write down each of the tasks that you require.
Write down each STEP of the tasks that you require.
Code those tasks (steps).
Compile and run often, to test each task step.
