This example generates a frequency table, which shows the number of occurrences of each letter within the Quranic text. An analysis table is used to tabulate and group the results.
Java Example
public class CharacterFrequencyExample {
public static void main() {
// Create a new analysis table.
AnalysisTable table = new AnalysisTable("Character");
// Add each character to the table.
for (Token token : Document.getTokens()) {
for (ArabicCharacter character : token) {
if (character.getType() != null) {
table.add(character.getType());
}
}
}
// Group and display results.
AnalysisTable groupTable = table.group("Character");
groupTable.sort("Count", SortOrder.Descending);
System.out.println(groupTable);
}
}
