RuleBasedCollator getCollationElementIterator(CharacterIterator) method in Java
The getCollationElementIterator() method of java.text.RuleBasedCollator class is used to get the object of collation element iterator for the given character iterator object.
Syntax:
public CollationElementIterator getCollationElementIterator(CharacterIterator source)
Parameter: This method accepts the character iterator object as a parameter.
Return Value: This method returns the object of collation element iterator for the given string.
Below are the examples to illustrate the getCollationElementIterator() method:
Example 1:
// Java program to demonstrate// getCollationElementIterator() method import java.text.*;import java.util.*;import java.io.*; public class GFG { public static void main(String[] argv) { try { // Creating and initializing // new simple rule String simple = "< a < b < c < d"; // Creating and initializing // new RuleBasedCollator Object RuleBasedCollator col = new RuleBasedCollator(simple); // Creating and initializing // StringCharacterIterator Object StringCharacterIterator obj = new StringCharacterIterator("Geeks"); // getting CollationElementIterator Object // for the given String // using getCollationElementIterator() method CollationElementIterator key = col.getCollationElementIterator(obj); // display result System.out.println( "CollationElementIterator is : " + key); } catch (ClassCastException e) { System.out.println("Exception thrown : " + e); } catch (ParseException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
CollationElementIterator is : java.text.CollationElementIterator@7d4991ad
Example 2:
// Java program to demonstrate// getCollationElementIterator() method import java.text.*;import java.util.*;import java.io.*; public class GFG { public static void main(String[] argv) { try { // Creating and initializing // new simple rule String simple = "< a < b & a < c"; // Creating and initializing // new RuleBasedCollator Object RuleBasedCollator col = new RuleBasedCollator(simple); // Creating and initializing // StringCharacterIterator Object StringCharacterIterator obj = new StringCharacterIterator("ABCDEF"); // getting CollationElementIterator Object // for the given StringCharacterIterator Object // using getCollationElementIterator() method CollationElementIterator key = col.getCollationElementIterator(obj); // display result System.out.println( "CollationElementIterator is : " + key); } catch (ClassCastException e) { System.out.println("Exception thrown : " + e); } catch (ParseException e) { System.out.println("Exception thrown : " + e); } }} |
