Constructor Detail

Data

public Data(String term)

Builds the Data object and ets the term for the Data.

Parameters:

term - the value to set to term

Method Detail

getColleges

public CollegeDemographics[] getColleges()

Gets the colleges stored in collegeDemographics.

NEW to implement in p4 - remember to add tests to your main for it.

Simply returns the values, so it can be used in other classes.

Returns:

collegeDemographics

getTermFriendlyName

public String getTermFriendlyName()

Takes the numeric name of a term, and returns the friendly name, which includes the Fall/Spring/Summer and the year. For example, Term 202110 would be Spring 2021, 202090 would be Fall 2020.

NEW to implement in p4 - remember to add tests to your main for it.

The first four characters are the year, and the 5th character determines the term. 1 == Spring, 6 == Summer, 9 == Fall

Implementation Hints: You can assume a consistent format, so String.substring and String.charAt will be useful. While not required, we used a switch statement, but you can also use an if/else if/else

Returns:

A friendly name of term

loadData

public void loadData(String filename)

Loads the data into the array objects. Uses CSVReader and as long as there are more lines continues to load gender demographic information.

A couple things to consider with implementation

• While CSVReader.hasNext(), loop though all the information
• If the array returned from CSVReader.getNext() has less than six values, skip.
• Look at the TERM location in the array returned. Is the value not equal to term, then skip it.
• Once all checks are done, call CollegeDemographics.addGenderDemographic(String, String)

Parameters:

filename - the name of the file that contains gender demographics

See Also:

CollegeDemographics.addGenderDemographic(String, String), CSVReader.getNext(), CSVReader.hasNext()

printStats

public void printStats()

Deprecated. This method was replaced by DemographicDataWriter.writeToScreen(Data)

For each college in collegeDemographics, loops through and prints the CollegeDemographics.getTable() to the console.

For P4, this method is deprecated, which means it isn't meant to be used. It is common practice to mark methods as deprecated, but not remove them in case other code depends on them.Eventually, after a certain time frame, deprecated methods are removed. The replacement method is actually a near copy of this method, depending on how you wrote it the first time.
