The next() method of java.text.CollationElementIterator class is used to get next Collator element. This method push the iterator to the next element and returns its value.

Syntax:

public int next()

Parameter: This method does accepts any parameter.

Return Value: This method returns the value of the next collator element as an integer value.

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

Example 1:




// Java program to demonstrate next() 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 = "abcd";
  
        // 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(1);
  
        // display the result
        System.out.println("current offset before"
                           + " calling next() "
                           + cel.getOffset());
  
        // getting offset of the next collator element
        // using next() method
        int value = cel.next();
  
        // display the result
        System.out.println("\ncurrent element value"
                           + " after calling next() "
                           + value);
    }
}


Output:

current offset before calling next() 1

current element value after calling next() 5439488

Example 2:




// Java program to demonstrate next() 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 = "abcd";
  
        // 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(2);
  
        // display the result
        System.out.println("current offset before"
                           + " calling next() "
                           + cel.getOffset());
  
        // getting offset of the next collator element
        // using next() method
        int value = cel.next();
  
        // display the result
        System.out.println("\ncurrent offset after"
                           + " calling next() "
                           + cel.getOffset());
    }
}


Output:

current offset before calling next() 2

current offset after calling next() 3
