This charSequence is taken as a parameter. The starting index and ending index to be written are also taken as parameters. Syntax: public void append(CharSequence charSequence, int startingIndex, int endingIndex) Parameters: This method accepts three mandatory parameters: charSequence which is the charSequence to be written in the Stream. startingIndex which is the starting index from which the portion of character is to taken. endingIndex which is the ending index to be written on the stream. Return Value: This method do not returns any value. Below methods illustrates the working of append(CharSequence, int, int) method: Program 1: Java // Java program to demonstrate // PrintWriter append(CharSequence, int, int) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a PrintWriter instance PrintWriter writer = new PrintWriter(System.out); // Get the charSequence // to be written in the stream CharSequence charSequence = "GeeksForGeeks"; // Get the starting index int startingIndex = 0; // Get the length of char int endingIndex = 5; // Write the portion of the charSequence // to this writer using append() method // This will put the charSequence in the stream // till it is printed on the console writer.append(charSequence, startingIndex, endingIndex); writer.flush(); } catch (Exception e) { System.out.println(e); } } } Output: Geeks Program 2: Java // Java program to demonstrate // PrintWriter append(CharSequence, int, int) method import java.io.*; class GFG { public static void main(String[] args) { try { // Create a PrintWriter instance PrintWriter writer = new PrintWriter(System.out); // Get the charSequence // to be written in the stream CharSequence charSequence = "GFG"; // Get the starting index int startingIndex = 2; // Get the length of char int endingIndex = 3; // Write the portion of the charSequence // to this writer using append() method // This will put the charSequence in the stream // till it is printed on the console writer.append(charSequence, startingIndex, endingIndex); writer.flush(); } catch (Exception e) { System.out.println(e); } } } Output: G Comment More infoAdvertise with us Next Article Must Coding Questions - Company-wise K Kirti_Mangal Follow Improve Article Tags : Java Java-Functions Java-IO package Java-PrintWriter Practice Tags : Java Similar Reads Interview PreparationInterview Preparation For Software DevelopersMust Coding Questions - Company-wise Must Do Coding Questions - Topic-wiseCompany-wise Practice ProblemsCompany PreparationCompetitive ProgrammingSoftware Design-PatternsCompany-wise Interview ExperienceExperienced - Interview ExperiencesInternship - Interview ExperiencesPractice @GeeksforgeeksProblem of the DayTopic-wise PracticeDifficulty Level - SchoolDifficulty Level - BasicDifficulty Level - EasyDifficulty Level - MediumDifficulty Level - HardLeaderboard !!Explore More...Data StructuresArraysLinked ListStackQueueBinary TreeBinary Search TreeHeapHashingGraphAdvance Data StructuresMatrixStringAll Data StructuresAlgorithmsAnalysis of AlgorithmsSearching AlgorithmsSorting AlgorithmsPattern SearchingGeometric AlgorithmsMathematical AlgorithmsRandomized AlgorithmsGreedy AlgorithmsDynamic ProgrammingDivide & ConquerBacktrackingBranch & BoundAll AlgorithmsProgramming LanguagesCC++JavaPythonC#Go LangSQLPHPScalaPerlKotlinWeb TechnologiesHTMLCSSJavaScriptBootstrapTailwind CSSAngularJSReactJSjQueryNodeJSPHPWeb DesignWeb BrowserFile FormatsComputer Science SubjectsOperating SystemsDBMSComputer NetworkComputer Organization & ArchitectureTOCCompiler DesignDigital Elec. & Logic DesignSoftware EngineeringEngineering MathematicsData Science & MLComplete Data Science CourseData Science TutorialMachine Learning TutorialDeep Learning TutorialNLP TutorialMachine Learning ProjectsData Analysis TutorialTutorial LibraryPython TutorialDjango TutorialPandas TutorialKivy TutorialTkinter TutorialOpenCV TutorialSelenium TutorialGATE CSGATE CS NotesGate CornerPrevious Year GATE PapersLast Minute Notes (LMNs)Important Topic For GATE CSGATE CoursePrevious Year Paper: CS exams Like
