CollationElementIterator getOffset() method in Java with Examples

  • Last Updated : 03 Jan, 2020

The getOffset() method of java.text.CollationElementIterator class is used to get the index of item present at collator currently pointed by CollationElementIterator.

Syntax:

public int getOffset()

Parameter: This method does not accept any parameter.

Return Value: This method returns the offset of element currently pointed by iterator.

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



Example 1:




// Java program to demonstrate getOffset() 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);
  
        // setting offset to index 4
        cel.setOffset(4);
  
        // getting offset of cel
        // using getOffset() method
        int value = cel.getOffset();
  
        // display the result
        System.out.println("current offset is "
                           + value);
    }
}
Output:
current offset is 4

Example 2:




// Java program to demonstrate getOffset() 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);
  
        // setting offset to index 4
        cel.setOffset(4);
  
        // calling next element
        cel.next();
  
        // getting offset of cel
        // using getOffset() method
        int value = cel.getOffset();
  
        // display the result
        System.out.println("current offset is "
                           + value);
    }
}
Output:
current offset is 5
