LATESLIP CLASS SOLUTIONS

TASK – PART 1 – LATESLIP CLASS: INSTANCE VARIABLES

My class so far:

public class LateSlip

{

private String name;

private String date;

private String time;

private char code; //L, A or E

private String author;

private boolean detention;

}

TASK – PART 2 – LATESLIP CLASS: CONSTRUCTORS

My class with the constructors.

public class LateSlip

{

private String name;

private String date;

private String time;

private char code; //L, A or E

private String author;

private boolean detention;

public LateSlip(String n, String da, String t, char c, String a, boolean de)

{

name = n;

date = da;

time = t;

code = c;

author = a;

detention = de;

}

public LateSlip(String n, String da, String t, char c, String a)

{

name = n;

date = da;

time = t;

code = c;

author = a;

detention = false;

}

}

TASK – PART 3 – LATESLIP CLASS: METHODS

My full class.

public class LateSlip

{

private String name;

private String date;

private String time;

private char code; //L, A or E

private String author;

private boolean detention;

public LateSlip(String n, String da, String t, char c, String a, boolean de)

{

name = n;

date = da;

time = t;

code = c;

author = a;

detention = de;

}

public LateSlip(String n, String da, String t, char c, String a)

{

name = n;

date = da;

time = t;

code = c;

author = a;

detention = false;

}

public String getName()

{

return name;

}

public String getDate()

{

return date;

}

public String getTime()

{

return time;

}

public char getCode()

{

return code;

}

public String getAuthor()

{

return author;

}

public boolean getDetention()

{

return detention;

}

public void addDetention()

{

detention = true;

}

public String toString()

{

String s = "";

s = s + "LOCKERBY COMPOSITE SCHOOL SLIP\n";

s = s + "Student: " + name + "\n";

s = s + "Date: " + date + "\n";

s = s + "Time: " + time + "\n";

if (code == 'L')

{

s = s + "LATE Admit Excused\n";

}

else if (code == 'A')

{

s = s + "Late ADMIT Excused\n";

}

else //if code is 'E'

{

s = s + "Late Admit EXCUSED\n";

}

s = s + "Authorized by: " + author + "\n";

if (detention == true)

{

s = s + "HAS DETENTION\n";

}

else

{

s = s + "No Detention\n";

}

return s;

}

}

TASK – PART 4 – TESTING

Here is my Tester class:

public class LateSlipTester

{

public static void main(String[] args)

{

LateSlip ls = new LateSlip("Pat Camp", "Oct 11, 2022", "9:26AM", 'L', "Mr. Lafraniere", true);

System.out.println(ls);

LateSlip ls2 = new LateSlip("Jimmy B", "Oct 11", "9:20", 'A', "Mr. Runciman");

System.out.println(ls2);

ls2.addDetention();

System.out.println(ls2);

}

}

The above code gives the following output:

LOCKERBY COMPOSITE SCHOOL SLIP

Student: Pat Camp

Date: Oct 11, 2022

Time: 9:26AM

LATE Admit Excused

Authorized by: Mr. Lafraniere

Date: Oct 11

Time: 9:20

Late ADMIT Excused
