CollationElementIterator setText(CharacterIterator) method in Java with Example

The setText() method of java.text.CollationElementIterator class is used to set the new source string for CollationElementIterator object to iterate. 

Syntax:

public void setText(CharacterIterator source)

Parameter: This method takes a new CharacterIterator object contains string value over which iterator is going to iterate. 

Return Value: This method has nothing to return. 

Below are the examples to illustrate the setText() method: 

Example 1:

Java

// Java program to demonstrate
// setText() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing testString
        String test = "GeeksForGeeks";

        // creating and initializing
        // RuleBasedCollator object
        RuleBasedCollator rbc
            = (RuleBasedCollator)(Collator.getInstance());

        // creating and initializing
        // CollationElementIterator
        CollationElementIterator cel
            = rbc.getCollationElementIterator(test);

        // creating and initializing
        // CharacterIterator object
        CharacterIterator str
            = new StringCharacterIterator("Code");

        // setting new text using
        // setText() method
        cel.setText(str);

        // for iteration
        for (int i = 1; i <= str.getEndIndex(); i++) {

            // getting primary component of every elmenet
            // using primaryOrder() method
            int value
                = CollationElementIterator
                      .primaryOrder(cel.next());

            // display the result
            System.out.println("primary order "
                               + "for order "
                               + i + " is "
                               + value);
        }
    }
}

Output:

primary order for order 1 is 84
primary order for order 2 is 97
primary order for order 3 is 85
primary order for order 4 is 87

Example 2:

Java

// Java program to demonstrate
// setText() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing testString
        String test = "GeeksForGeeks";

        // creating and initializing
        // RuleBasedCollator object
        RuleBasedCollator rbc
            = (RuleBasedCollator)(Collator.getInstance());

        // creating and initializing
        // CollationElementIterator
        CollationElementIterator cel
            = rbc.getCollationElementIterator(test);

        // creating and initializing
        // CharacterIterator object
        CharacterIterator str
            = new StringCharacterIterator("GeeksForGeeks");

        // setting new text using
        // setText() method
        cel.setText(str);

        // for iteration
        for (int i = 1; i <= str.getEndIndex(); i++) {

            // getting primary component of every elmenet
            // using primaryOrder() method
            int value
                = CollationElementIterator
                      .primaryOrder(cel.next());

            // display the result
            System.out.println("primary order "
                               + "for order "
                               + i + " is "
                               + value);
        }
    }
}

Output:

primary order for order 1 is 89
primary order for order 2 is 87
primary order for order 3 is 87
primary order for order 4 is 93
primary order for order 5 is 101
primary order for order 6 is 88
primary order for order 7 is 97
primary order for order 8 is 100
primary order for order 9 is 89
primary order for order 10 is 87
primary order for order 11 is 87
primary order for order 12 is 93
primary order for order 13 is 101
