I already have the code for the assignment below, but there is some errors in the code. Please help me fix them.
The assignment:
Make a telephone lookup program. Read a data set of 1,000 names and telephone numbers from a file that contains the numbers in random order. Handle lookups by name and also reverse lookups by phone number. Use a binary search for both lookups. This assignment needs a resource class and a driver class. The resource class and the driver class will be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java. Please help me with exactly what I asked for help.
The code:
PhoneLookup.java
import java.io.FileReader;import java.io.IOException;import java.util.Scanner;

- During the sockets lab we cast the second parameter from a struct sockaddr_in to a struct sockaddr. struct sockaddr_in address; /* ... */ bind(server_fd, (struct sockaddr*)&address, sizeof(address)) This provides a limited form of polymorphism: bind only needs the first few fields of its struct, and both struct sockaddr_in and struct sockaddr have the same fields at those addresses.
