public void setText(String source)

Parameter: This method takes a new source string over which the 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);
 
        String str = "Code";
 
        // setting new text using
        // setText() method
        cel.setText(str);
 
        // for iteration
        for (int i = 1; i <= str.length(); i++) {
 
            // getting primary component of every element
            // 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);
 
        String str = "Tajmahal";
 
        // setting new text using
        // setText() method
        cel.setText(str);
 
        // for iteration
        for (int i = 1; i <= str.length(); i++) {
 
            // getting primary component of every element
            // 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 102
primary order for order 2 is 82
primary order for order 3 is 92
primary order for order 4 is 95
primary order for order 5 is 82
primary order for order 6 is 90
primary order for order 7 is 82
primary order for order 8 is 94
