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); } } |
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); } } |
current offset is 5
