In the situation where there are multiple users or a networked computer system, you probably share a printer with other users. When you request to print a file, your request is added to the printer. When your request reaches the front of the printing line, your file is printed.
In the situation where there are multiple users or a networked computer system, you probably share a printer with other users. When you request to print a file, your request is added to the printer.
When your request reaches the front of the printing line, your file is printed. This ensures that only one person at a time has access to the printer and that this access is given on first-come, first-served basis.
Keeping that in mind when ever a new request is generated, OS will put the file in line and prints the file which comes earlier(first). After printing the OS checks the next file and prints the next file and this goes on until all files gets printed.
Implement the above scenario what you have to do is:
Make a File class which keeps Id, name, number of pages.
Create a Printer class which takes File type array.
The Printer class implements the operation “add” which adds a new file to the line by checking the available space.
A remove() method in Printer class which removes the file from the printer which gets printed.
A display function in Printer class which prints all the files waiting to be printed.
