Constructor Detail

CrimeRecord

public CrimeRecord()

This constructor performs default initialization to all members.

CrimeRecord

public CrimeRecord(double x,
                   double y,
                   int time,
                   java.lang.String street,
                   java.lang.String offense,
                   java.lang.String date,
                   java.lang.String tract,
                   double lat,
                   double lon)

This constructor sets all members of a CrimeRecord object.

Parameters:

x - double x-coordinate in State Plane coordinate system

y - double y-coordinate in State Plane coordinate system State plane is useful for computing distance between crimes.

time - int time represents time of day the crime occurred

street - String street address of crime

offense - String crime type (Robbery and so on)

date - String date of crime

tract - String tract

lat - double lat latitude used for display

lon - double lon longitude used for display

Method Detail

getDate

public java.lang.String getDate()

getLat

public double getLat()

getLon

public double getLon()

getOffense

public java.lang.String getOffense()

getStreet

public java.lang.String getStreet()

getTime

public int getTime()

getTract

public java.lang.String getTract()

getX

public double getX()

getY

public double getY()

setDate

public void setDate(java.lang.String date)

setLat

public void setLat(double lat)

setLon

public void setLon(double lon)

setOffense

public void setOffense(java.lang.String offense)

setStreet

public void setStreet(java.lang.String street)

setTime

public void setTime(int time)

setTract

public void setTract(java.lang.String tract)

setX

public void setX(double x)

setY

public void setY(double y)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

a string containing all member data

parseLine

public static CrimeRecord parseLine(java.lang.String line)

pre: line contains comma separated values of crime data - as shown by each line in the file.

Parameters:

line - is a single line of input from the crime file. This routine makes good use of the split method in the String class. It calls the setter members as it gathers the data from the string.

Returns:

a new CrimeRecord object holding the data from the Sting line

distanceBetween

public static double distanceBetween(CrimeRecord a,
                                     CrimeRecord b)

pre: two crime records contain valid State Plane coordinate data

Parameters:

a - CrimeRecard

b - CrimeRecord

Returns:

distance in feet between crime A and crime b
