StringBuilder offsetByCodePoints() method in Java with Examples Last Updated : 20 Oct, 2018 Comments Improve Suggest changes Like Article Like Report The offsetByCodePoints() method of StringBuilder class returns the index within this String contained by StringBuilder that is offset from the index passed as parameter by codePointOffset code points. Unpaired surrogates lies between index and codePointOffset count as one code point each. Syntax: public int offsetByCodePoints(int index, int codePointOffset) Parameters: This method takes two parameters: index: the index to be offset codePointOffset: the offset in code points Return Value: This method returns the index within this sequence. Exception: This method throws IndexOutOfBoundsException if any one below is true: index < 0 or index > length of the sequence. codePointOffset > 0 and the subsequence starting with index has fewer than codePointOffset code points codePointOffset < and the subsequence before index has fewer than the absolute value of codePointOffset code points. Below programs demonstrate the offsetByCodePoints() method of StringBuilder Class: Example 1: Java // Java program to demonstrate // the offsetByCodePoints() Method. class GFG { public static void main(String[] args) { // create a StringBuilder object // with a String pass as parameter StringBuilder str = new StringBuilder("WelcomeGeeks"); // print string System.out.println("String = " + str.toString()); // returns the index within this sequence int returnvalue = str.offsetByCodePoints(1, 4); // prints the index System.out.println("Index = " + returnvalue); } } Output: String = WelcomeGeeks Index = 5 Example 2: Java // Java program to demonstrate // the offsetByCodePoints() Method. class GFG { public static void main(String[] args) { // create a StringBuilder object // with a String pass as parameter StringBuilder str = new StringBuilder("India Is great"); // print string System.out.println("String = " + str.toString()); // returns the index within this sequence int returnvalue = str.offsetByCodePoints(2, 9); // prints the index System.out.println("Index = " + returnvalue); } } Output: String = India Is great Index = 11 Example 3: To demonstrate IndexOutOfBoundException Java // Java program to demonstrate // Exception thrown by offsetByCodePoints() Method. class GFG { public static void main(String[] args) { // create a StringBuilder object // with a String pass as parameter StringBuilder str = new StringBuilder("India"); try { // returns the index within this sequence int returnvalue = str.offsetByCodePoints(2, 9); // prints the index System.out.println("Index = " + returnvalue); } catch (IndexOutOfBoundsException e) { System.out.println("Exception: " + e); } } } Output: Exception: java.lang.IndexOutOfBoundsException Reference: https://docs.oracle.com/javase/10/docs/api/java/lang/StringBuilder.html#offsetByCodePoints(int, int) Comment More infoAdvertise with us Next Article StringBuilder offsetByCodePoints() method in Java with Examples A AmanSingh2210 Follow Improve Article Tags : Java java-basics Java-Functions Java-StringBuilder Practice Tags : Java Similar Reads StringBuffer offsetByCodePoints() method in Java with Examples The offsetByCodePoints() method of StringBuffer class returns the index within this String contained by StringBuffer that is offset from the index passed as parameter by codePointOffset code points.
