Could someone explain to me what exactly is messing up?

I am working on a group project, and my partner bailed on me, and just left me with his broken half of the code. I have finished his half and mine, but Its not exactly compiling right. Could someone take a look at it and point me in the direction of my mistake?

Here is the assignment:

In this project, you must implement a simplified version of the student registration system. In particular, your system must present a
student with a set of courses, with all their relevant information, and allow the student to select five courses, one at a time, that do not
conflict in day or time.

If we restate the requirements for this assignment in a single sentence, we might say the following:
“The user selects courses from a set of offerings such that the day and time ranges of each course do not conflict with the day and time
ranges of the other selected courses.” With that restatement, we can pick out the nouns to begin our object-oriented design. Here, the
nouns are “user,” “course,” “offering,” “day,” “time,” and “range.” In this case, the user should probably not be a class itself, but the
others (excepting “day”) make a lot of sense. So we'll use those four classes for the solution.

The specific requirements for each class are presented below. Each team must distribute these classes one per member to be
implemented according to the given specifications. Each member will be scored individually based on his own implemented class,
which must, at a minimum, pass all unit tests provided to be considered satisfactory. The individual performance represents 70% of the
individual's grade, with the other 30% to be determined from the group submission.

Time
This class represents an hour-minute designation for a time of day. It should represent hours in military (24-hour) time, where, for
example, 3pm is represented as 1500. It should allow time to be specified as both an hour-minute pair of integers (within the
appropriate ranges) or as a string like “1530”. The class should also allow comparisons of two Time objects so as to know whether one
comes before, after, or is equal to another.

Private Attributes
int hour
must be in range [0, 23]

int minute
must be in range [0, 59]

Private Methods
String pad(String time)
pads a given string representing a time with leading zeros, so that, for instance, “115” becomes “0115”.

int[] convertStringToHoursMins(String time)
converts a (possibly unpadded) string to hours and minutes, which are returned as a two-element array of integers where element 0 is
hours and element 1 is minutes. This method may throw a NumberFormatException if the string contains elements that cannot be
converted to integers.

Public Methods
Time()
default constructor that initializes the time to midnight (0 hour and 0 minute).

Time(String time)
constructor that initializes the time to the value contained in the string argument. The value of the string must be a valid time;
otherwise, the constructor initializes the object to midnight.

Time(int hour, int minute)
constructor that initializes the time to the hour and minute specified. The values for hour and minute must be within the valid ranges;
otherwise, they are replaced with zeros.

int getHour()
returns the hour

void setHour(int hour)
sets the hour, if it is within the allowed range

int getMinute()
returns the minute

void setMinute(int minute)
sets the minute, if it is within the allowed range

void setTime(String time)
sets the time based on the given string, if it contains legal hour and minute values

boolean before(Time time)
returns true if the time held in the current object occurs before the time object being passed

boolean after(Time time)
returns true if the time held in the current object occurs after the time object being passed

boolean equals(Time time)
returns true if the time held in the current object is the same as the time object being passed

String toString()
returns the string representation of the current object, which should be of the form “HHMM”

TimeRange
This class represents a duration or range of time marked by a starting and ending time. This class does not allow for such a range of
time to extend to the following day. In other words, the start time must always come before the end time without considering the days.
So defining a range like 1900 to 0200 (7pm to 2am) would instead be interpreted as 0200 to 1900 (2am to 7pm).

Private Attributes
Time startTime
Time endTime
the starting and ending times for the range. The start time must always come before the end time.

Public Methods
TimeRange(Time startTime, Time endTime)
constructor that takes a start and end time and initializes the object. If the start time does not come before the end time, the constructor
switches them around to make the range meaningful.

Time getStartTime()
Time getEndTime()
returns the start and end times, respectively. Note that there are no equivalent setter methods here. This is because a setter method
might violate the “start comes before end” property, forcing the time range to rearrange itself to remain meaningful. Instead, any
changes must be done by instantiating a new TimeRange object.

int getDuration()
returns the duration in minutes of the range

boolean contains(Time time)
returns true if the current TimeRange object contains the time passed in. For instance, the time range (1000, 1400) contains 1030 (and
1000 and 1400 and all times in between) but does not contain 0800 or 1500 (or 1401, for that matter).

boolean overlaps(TimeRange otherTime)
returns true if the current TimeRange object overlaps the TimeRange object passed in. For instance, the time range(1000, 1400)
overlaps the ranges (1100, 1500), (1030, 1130), and (0900, 1430), but it does not overlap the range (0800, 0900).

String toString()
returns the string representation of the time range of the form “HHMM-HHMM” where the first time is the start and the second is the
end

Here is a test program that my teacher gave us in order to test the timeRange (my particular part in the project) :

import junit.framework.*;
 
public class TestTimeRange extends TestCase { 
    private TimeRange t;
    private TimeRange u;
    public TestTimeRange(String name) {
        super(name);
    }
    protected void setUp() { 
        t = new TimeRange(new Time(11, 30), new Time(10, 00));
        u = new TimeRange(new Time(11, 0), new Time(14, 0));
    }
    public void testGets() {
        assertEquals("1000", t.getStartTime().toString());
        assertEquals("1130", t.getEndTime().toString());
        assertEquals("1100", u.getStartTime().toString());
        assertEquals("1400", u.getEndTime().toString());
    }
    public void testGetDuration() {
        assertEquals(90, t.getDuration());
        assertEquals(180, u.getDuration());
    }
    public void testContains() {
        assertTrue(t.contains(new Time("1100")));
        assertTrue(t.contains(new Time("1000")));
        assertTrue(!t.contains(new Time("0959")));
        assertTrue(!t.contains(new Time("1131")));
    }
    public void testOverlaps() {
        assertTrue(t.overlaps(u));
        assertTrue(!t.overlaps(new TimeRange(new Time("1400"), new Time("1500"))));
    }

error: ')' expected

That error says what the problem is. The code needs a ) near where the ^ is.

One big problem I see is that the Time class's code is poorly formatted. There should never be a } directly below another }. That makes it very hard to read and understand the nesting of the logic. Nested statements and blocks need to be indented 3-4 spaces to show the logic.

Most of those errors are probably due to misplaced code and/or {}s. Properly formatting the code should show where the problem is. When that error is fixed, the list of errors will be much shorter.

okay, I have fixed all of the errors on the Time class, and now just have the following 6 errors for the TimeRange class:

bad operand types for binary operator '>'

The > operator is for numeric primitive operands. Objects need to use methods to compare their contents.

cannot find symbol

The compiler can not find the symbol shown in the error message. Check if the variable/method is defined and spelled correctly.

Okay, I have fixed all of the errors in the TimeRange class. Now when I try and run the code that the teacher gave us to test our classes I get these errors:

package junit.framework does not exist

Do you have a jar file with that package in it? Add it to the classpath so the compiler can find it.
When the compiler can find that package, most of the "cannot find symbol" should go away.

All that I have is the JDK that my teacher installed onto my computer. How do I get the jar file?

How do I get the jar file?

Ask your teacher where the package named in the error message is defined.
Try asking Google also.

Thank you! I really appreciate it!
