Question

a)You can begin by reading the html file. R makes this easy to do

Your first task is to write code to count the total number of faculty in the department. Everyone listed on the website is a member of the faculty. Report your answer.

b) Now count the number of “full professors”. A “full professor” is someone who is listed as a professor but does not have the term “assistant” or “associate” in their title. For example, a Distinguished Professor is a “full professor” but an “Assistant Teaching Professor” is not a full professor.

c) List the various categories of faculty in the department. That is, find all the titles and only list the ones that are unique, e.g. Professor, Assistant Teaching Professor, Instructor, and so on. Read through your list carefully – make sure that you are not repeating categories (pay attention to spaces, typos and abbreviations). Report both the number of categories as well as the number of people in each category.

d) Create a data frame that contains all the names of faculty who are listed as Assistant Teaching Professor. The first column should be the last name and the second column should be the first name.

e) What proportion of faculty in the department have “teaching” in their title? What proportion have “research” in their title?

import java.net.URL;

import java.net.URLConnection;

import java.util.HashMap;

import java.util.Map;

public class ShowDetail {

public static void main(String[] args) throws Exception {

// TODO Auto-generated method stub

URL website = new URL("http://stat.psu.edu/people/faculty");

URLConnection connection = website.openConnection();

BufferedReader in = new BufferedReader(

new InputStreamReader(

connection.getInputStream()));

String inputLine;

String nextLine;

String jobTitle;

int count =0;

int totalCount = 0;

Map<String,Integer> propessorsCountMap = new HashMap<String,Integer>();

while ((inputLine = in.readLine()) != null){

if(inputLine.contains("jobTitle")){

totalCount = totalCount +1;

nextLine = in.readLine();

if(nextLine != null){

jobTitle = nextLine.replace("<li>", "").replace("</li>", "").trim();

if (propessorsCountMap.get(jobTitle) != null){

count = propessorsCountMap.get(jobTitle);

count = count+1;

propessorsCountMap.put(jobTitle,count);

} else {

propessorsCountMap.put(jobTitle, 1);

}

}

}

}

System.out.println("total number of faculty :: "+totalCount);

int fullProfessorsCount = 0;

for (Map.Entry<String,Integer> entry : propessorsCountMap.entrySet()) {

if(!(entry.getKey().contains("Assistant")) && !(entry.getKey().contains("Associate"))){

fullProfessorsCount = fullProfessorsCount +entry.getValue();

}

}

System.out.println("full professor count :: "+fullProfessorsCount);

for (Map.Entry<String,Integer> entry : propessorsCountMap.entrySet()) {

System.out.println("category::"+entry.getKey() + " count::"+entry.getValue());

}

in.close();

}

}

output :

total number of faculty :: 57
full professor count :: 24
category::Professor count::9
category::Verne M. Willaman Professor count::1
category::Associate Professor count::2
category::Instructor count::4
category::Teaching Lecturer count::2
