Java Programming:
In this programming assignment, you need to implement a storage manager that maintains a
series of data objects in each data file. Include a main method file as well. Below is the
FileManager.java that has errors. Attached are images where the errors are circled. Make sure
there are no error in the code at all and show the output.

public class FileManager {
public void put(int fileID, Long location, Object o) throws IOException,
InvalidLocationException {
if (first(location) < 0) {
throw new InvalidLocationException();
}
SlottedPage p = page(fileID, first(location));
p.put(second(location), o);
updated(p, fileID);
