Clean Code Kata
Under the path /samples you can find CSV-Files, which we want to read in and display to the user.
A very kind front-end-team has already implemented two user interfaces for us, yay =)
Our job now is to breathe in some life to the GUI with the contents of the CSV-files.
For the sake of simlicity and educational character of this exercise we can assume well formed CSV-Files. Our goal is not to create a perfect almighty CSV-Reader!
Input file: input-1-no-header.csv
For this task relevant GUI-APIs:
public interface CsvUi {
/**
* sets the amount of columns in the ui.
*
* @param amount
* number of columns.
*/
public void setColumnCount(int amount);
/**
* adds a row to the ui.
*
* @param data
* a list of data elements for each column.
* @throws IllegalArgumentException
* if data.size() is not the size of columns in the ui.
*/
public void addRow(List<String> data);
}Input file: input-2-with-header.csv
For this task relevant GUI-APIs:
public interface CsvUi {
/**
* adds a column to ui.
*
* @param caption
* of the column
* @throws IllegalArgumentException
* if caption is null or empty.
* @throws IllegalStateException
* if data is in the view
*/
public void addColumn(String caption);
/**
* adds a row to the ui.
*
* @param data
* a list of data elements for each column.
* @throws IllegalArgumentException
* if data.size() is not the size of columns in the ui.
*/
public void addRow(List<String> data);
}Input file: input-2-with-header.csv
Hint: Your CsvReader class needs to implement the provided and untouchable interface Filterable.
For this task relevant GUI-APIs:
/**
* Defines a filterable table source.
*/
public interface Filterable {
/**
* filters the datasource based on the given word.
*
* @param col
* the column which shall contain the word
* @param word
* the word will be search as contains
* @return a list of rows fullfilling the filter
*/
public List<List<String>> filter(int col, String word);
}
public interface CsvUi {
/**
* adds a column to ui.
*
* @param caption
* of the column
* @throws IllegalArgumentException
* if caption is null or empty.
* @throws IllegalStateException
* if data is in the view
*/
public void addColumn(String caption);
/**
* adds a row to the ui.
*
* @param data
* a list of data elements for each column.
* @throws IllegalArgumentException
* if data.size() is not the size of columns in the ui.
*/
public void addRow(List<String> data);
