Object Orientation Program Help.
I am totally lost with this program. I've been working on it for a while and still nothing. I've been to tutoring multiple times, and I am getting more confused. This program is due today and I really need help. Thank you.
Below are two classes. The person class and the 314 class (object). Embedded in the code are comments that tell you what the professor is asking for. I have already written part of the person class.
Person class:
// person class
public class person {
private String Name;
private char sex;
private String score;
private int[] grades = new int[5];
private String newName;
public person() // CONSTRUCTOR
{
}
public void setName(String g) // RECEIVE NAME
{Name = g; }
public void setSex(char c) // RECEIVE SEX CODE
{sex = c;};
public void setScore(String cat) // RECEIVE SCORES AS STRING
{score = cat;}
public void fixName()
{
/* HERE IS WHERE YOY TAKE YOUR STRING name
CONVERT IT TO LOWWER CASE, BREAK IT INTO 2 STRINGS
(FIRST AND LAST), CONVERT THE FIRST LETTER OF EACH
PART TO CAPITAL, AND CONCATENATE IT BACK TOGETHER AND
STORE IT IN newname.
*/
String last, first;
first = Name.substring(1, Name.indexOf(" "));
first = first.toLowerCase();
first = Name.charAt(0) + first;
newName = Name.toLowerCase();
System.out.println(first);
last = Name.substring(Name.indexOf(" ")+2, Name.length());
last = last.toLowerCase();
last = Name.charAt(Name.indexOf(" ")+1) + last;
newName = Name.toLowerCase();
System.out.println(last);
}
public void fixScore()
{
/*HERE YOU TAKE YOUR STRING CALLED scores ABOVE AND USE
AND STORE IT IN YOUR INTEGER ARRAY CALLED GRADES (ABOVE).
//10 objects sitting in this method
//pp=(Person)vector.get(a) where a is 0-9
*/
String score;
//
//grades?
}
public String getName() // RETURNS NEWNAME
{return newName;}
public char getSex() // RETURNS SEX CODE
{return sex;}
//---provide a function that will return the 5 scores for that person.
//You cannot return an array reference.. find another way.
}
314 Class:
import java.io.RandomAccessFile;
import java.io.EOFException;
import java.io.IOException;
import java.util.Vector;
public class First_314_Project
{
private RandomAccessFile raf;
//The entire path to the location of the file
private final String fileToRead = "DATA314.dat";
private Vector vector = new Vector();
private String temp;
private int c=0;
private person pp;
private String[] Names = new String[10];
private char[] Sex = new char[10];
private int[][] Score = new int[10][5];
private float[] averages = new float[5];
private char[] letter = new char[10];
public First_314_Project()
{
int counter=0;
try{
raf = new RandomAccessFile(fileToRead,"r");
do{
temp=raf.readUTF(); // raf is an object of the random access file class
//System.out.println(temp);
person p = new person();
int c = temp.indexOf(':');
String g = temp.substring(0,c);
char b = temp.charAt(c+1);
String cat = temp.substring(c+3,temp.length());
p.setName(g);
p.setSex(b);
p.setScore(cat);
p.fixName();
//find the blank
//get the first name
//get the last name
//use a substring command and grab position 1 through n-1 grab first name and leave the first letter alone
// take them apart and concenate them to create the correct order of the names. dont forget to put the comma inbetween the two
//last name first and then the first name
//convert the whole thing to lower case first if i want to
//capitalize the names in each part
p.fixScore();
counter++;
vector.add(p); // add person object to vector
}
while(counter<10);
counter=0;
/* here you should read all you data back from the vector and
store it in the arrays for sorting and printing
*/
pp= new person();
//for(int a=0; a<=9; a++) {
//pp= (person)vector.get(a);
//Names[a]=pp.getName();
//catch(Exception ex){}
function1(); // remember to pass arrays
function2(); // remember to pass arrays
}
catch(IOException e)
{System.err.println("File Error:" + e);}
}
public void function1( )
{
// this function will receive all arrays and compute average, letter grade
// and sort the arrays based upon average (high to low)
// You must use a pointer technique -- I will explain
}
public void function2( )
{
//this function will do all printing
//for(int a=0; a<=9; a++) {
//System.out.println(Names[a]);
}
public static void main()
{
new First_314_Project();
}
}
