* <p>
|

* You can use one of the predefined formats:

|
||||
*
|
||||
* <ul>
|
||||
* <li>{@link #DEFAULT}</li>

* </ul>
|
||||
* <p>For example:</p>
|

* <pre>CSVParser parser = CSVFormat.EXCEL.parse(reader);</pre>
|
||||
* <p>The {@link CSVRecord} provides static methods to parse other input types, for example:</p>
|
||||
*
|
||||
* <p>
|
||||
* For example:
|
||||
* </p>
|
||||
*
|
||||
* <pre>
|
||||
* CSVParser parser = CSVFormat.EXCEL.parse(reader);

|

* <pre>CSVParser parser = CSVFormat.parseFile(file, CSVFormat.EXCEL);</pre>
|
||||
*
|
||||
* <h4>Defining formats</h4>
|
||||
*
|
||||
* <p>
|
||||
* You can extend a format by calling the {@code with} methods. For example:
|
||||
* </p>
|
||||
* <pre>CSVFormat.EXCEL
|
||||
*
|
||||
* <pre>
|
||||
* CSVFormat.EXCEL
|
||||
* .withNullString("N/A")
|
||||
* .withIgnoreSurroundingSpaces(true);</pre>
|
||||
* .withIgnoreSurroundingSpaces(true);
|
||||
* </pre>
|
||||
*
|
||||
* <h4>Defining column names</h4>
|
||||
*
|
||||
* <p>
|
||||
* To define the column names you want to use to access records, write:
|
||||
* </p>
|
||||
* <pre>CSVFormat.EXCEL.withHeader("Col1", "Col2", "Col3");</pre>
|
||||
*
|
||||
* <pre>
|
||||
* CSVFormat.EXCEL.withHeader("Col1", "Col2", "Col3");
|
||||
* </pre>
|
||||
*
|
||||
* <p>
|
||||
* Calling {@link #withHeader(String...)} let's you use the given names to address values in a {@link CSVRecord}, and
|
||||
* assumes that your CSV source does not contain a first record that also defines column names. If it does, then
|
||||
* you are overriding this metadata with your names and you should skip the first record by calling
|
||||
* assumes that your CSV source does not contain a first record that also defines column names.
|
||||
*
|
||||
* If it does, then you are overriding this metadata with your names and you should skip the first record by calling
|
||||
* {@link #withSkipHeaderRecord(boolean)} with {@code true}.
|
||||
* </p>
|
||||
*
|
||||
* <h4>Parsing</h4>
|
||||
*
|
||||
* <p>
|
||||
* You can use a format directly to parse a reader. For example, to parse an Excel file with columns header, write:
|
||||
* </p>
|
||||
* <pre>Reader in = ...;
|
||||
*CSVFormat.EXCEL.withHeader("Col1", "Col2", "Col3").parse(in);</pre>
|
||||
*
|
||||
* <pre>
|
||||
* Reader in = ...;
|
||||
* CSVFormat.EXCEL.withHeader("Col1", "Col2", "Col3").parse(in);
|
||||
* </pre>
|
||||
*
|
||||
* <p>
|
||||
* For other input types, like resources, files, and URLs, use the static methods on {@link CSVParser}.
|
||||
* </p>
|
||||
*
|
||||
* <h4>Referencing columns safely</h4>
|
||||
*
|
||||
* <p>
|
||||
* If your source contains a header record, you can simplify your code and safely reference columns,
|
||||
* by using {@link #withHeader(String...)} with no arguments:
|
||||
* </p>
|
||||
* <pre>CSVFormat.EXCEL.withHeader();</pre>
|
||||
*
|
||||
* <pre>
|
||||
* CSVFormat.EXCEL.withHeader();
|
||||
* </pre>
|
||||
*
|
||||
* <p>
|
||||
* This causes the parser to read the first record and use its values as column names.
|
||||
*
|
||||
* Then, call one of the {@link CSVRecord} get method that takes a String column name argument:
|
||||
* </p>
|
||||
* <pre>String value = record.get("Col1");</pre>
|
||||
*
|
||||
* <pre>
|
||||
* String value = record.get("Col1");
|
||||
* </pre>
|
||||
*
|
||||
* <p>
|
||||
* This makes your code impervious to changes in column order in the CSV file.
|
||||
* </p>
|
||||
*
|
||||
* <h4>Notes</h4>
|
||||
*
|
||||
* <p>
|
||||
* This class is immutable.

||||
