StringBuffer offsetByCodePoints() method in Java with Examples Last Updated : 04 Dec, 2018 Comments Improve Suggest changes Like Article Like Report 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. 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 StringBuffer Class: Example 1: Java // Java program to demonstrate // the offsetByCodePoints() Method. class GFG { public static void main(String[] args) { // create a StringBuffer object // with a String pass as parameter StringBuffer str = new StringBuffer("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 StringBuffer object // with a String pass as parameter StringBuffer str = new StringBuffer("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 StringBuffer object // with a String pass as parameter StringBuffer str = new StringBuffer("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/StringBuffer.html#offsetByCodePoints(int, int) Comment More infoAdvertise with us A AmanSingh2210 Follow Improve Article Tags : Java java-basics Java-lang package Java-Functions java-StringBuffer +1 More Practice Tags : Java Explore BasicsIntroduction to Java4 min readJava Programming Basics9 min readJava Methods7 min readAccess Modifiers in Java6 min readArrays in Java9 min readJava Strings8 min readRegular Expressions in Java7 min readOOPs & InterfacesClasses and Objects in Java10 min readJava Constructors10 min readJava OOP(Object Oriented Programming) Concepts10 min readJava Packages7 min readJava Interface11 min readCollectionsCollections in Java12 min readCollections Class in Java13 min readCollection Interface in Java6 min readIterator in Java5 min readJava Comparator Interface6 min readException HandlingJava Exception Handling8 min readJava Try Catch Block4 min readJava final, finally and finalize4 min readChained Exceptions in Java3 min readNull Pointer Exception in Java5 min readException Handling with Method Overriding in Java4 min readJava AdvancedJava Multithreading Tutorial3 min readSynchronization in Java10 min readFile Handling in Java5 min readJava Method References9 min readJava 8 Stream Tutorial15+ min readJava Networking15+ min readJDBC Tutorial12 min readJava Memory Management4 min readGarbage Collection in Java6 min readMemory Leaks in Java3 min readPractice JavaJava Interview Questions and Answers15+ min readJava Programs - Java Programming Examples8 min readJava Exercises - Basic to Advanced Java Practice Programs with Solutions7 min readJava Quiz | Level Up Your Java Skills1 min readTop 50 Java Project Ideas For Beginners and Advanced [Update 2025]15+ min read Like
