CollationElementIterator getMaxExpansion() method in Java with Examples

0 0 2 minutes read

The getMaxExpansion() method of java.text.CollationElementIterator class is used to get the maximum expansion that any specified sequence ending can reach.
Syntax:

public int getMaxExpansion(int order)

Parameter: This method takes an collation element as parameter in the integer format for which maximum length has to be found
Return Value: This method returns the maximum expansion that any specified sequence ending can reach.
Below are the examples to illustrate the getMaxExpansion() method:
Example 1:

Java

// Java program to demonstrate
// getMaxExpansion() 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);
 
        // for iteration
        for (int i = 1; i <= test.length(); i++) {
 
            // getting maximum expansion
            // using getMaxExpansion() method
            int value
                = cel.getMaxExpansion(cel.next());
 
            // display the result
            System.out.println("maximum expansion "
                               + "for order "
                               + i + " is "
                               + value);
        }
    }
}

Output

maximum expansion for order 1 is 1
maximum expansion for order 2 is 1
maximum expansion for order 3 is 1
maximum expansion for order 4 is 1
maximum expansion for order 5 is 1
maximum expansion for order 6 is 1
maximum expansion for order 7 is 1
maximum expansion for order 8 is 1
maximum expansion for order 9 is 1
maximum expansion for order 10 is 1
maximum expansion for order 11 is 1
maximum expansion for order 12 is 1
maximum expansion for order 13 is 1

Example 2:

Java

// Java program to demonstrate
// getMaxExpansion() 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
            = "Code Geeks 123";
 
        // creating and initializing
        // RuleBasedCollator object
        RuleBasedCollator rbc
            = (RuleBasedCollator)(Collator
                                      .getInstance());
 
        // creating and initializing
        // CollationElementIterator
        CollationElementIterator cel
            = rbc.getCollationElementIterator(test);
 
        // for iteration
        for (int i = 1; i <= test.length(); i++) {
 
            // getting maximum expansion
            // using getMaxExpansion() method
            int value
                = cel.getMaxExpansion(cel.next());
 
            // display the result
            System.out.println("maximum expansion"
                               + " for order "
                               + i + " is "
                               + value);
        }
    }
}

Output

maximum expansion for order 1 is 1
maximum expansion for order 2 is 1
maximum expansion for order 3 is 1
maximum expansion for order 4 is 1
maximum expansion for order 5 is 1
maximum expansion for order 6 is 1
maximum expansion for order 7 is 1
maximum expansion for order 8 is 1
maximum expansion for order 9 is 1
maximum expansion for order 10 is 1
maximum expansion for order 11 is 1
maximum expansion for order 12 is 1
maximum expansion for order 13 is 1
maximum expansion for order 14 is 1
