StringBuilder appendCodePoint() method in Java with Examples Last Updated : 13 Dec, 2021 Comments Improve Suggest changes Like Article Like Report The appendCodePoint(int codePoint) method of StringBuilder class is the inbuilt method used to append the string representation of the codePoint argument to this sequence. The argument is appended to this StringBuilder content and length of the object is increased by Character.charCount(codePoint). The effect is the same as if the int value in parameter is converted to a char array and the character in that array were then appended to this character sequence. Syntax: public StringBuilder appendCodePoint(int codePoint) Parameters: This method accepts only one parameter codePoint which is int type value refers to a Unicode code point. Return Value: This method returns reference to this object.Below programs illustrate the java.lang.StringBuilder.appendCodePoint() method:Example 1: Java // Java program to illustrate the // appendCodePoint(int codePoint) import java.lang.*; public class Geeks { public static void main(String[] args) { // create StringBuilder object StringBuilder str = new StringBuilder("GeeksforGeeks"); System.out.println("StringBuilder = " + str); // Append 'C'(67) to the String str.appendCodePoint(67); // Print the modified String System.out.println("Modified StringBuilder = " + str); } } Output: StringBuilder = GeeksforGeeks Modified StringBuilder = GeeksforGeeksC Example 2: Java // Java program to illustrate the // appendCodePoint(int codePoint) import java.lang.*; public class Geeks { public static void main(String[] args) { // create StringBuilder object StringBuilder str = new StringBuilder("GeeksforGeeks"); System.out.println("StringBuilder = " + str); // Append ', '(44) to the String str.appendCodePoint(44); // Print the modified String System.out.println("Modified StringBuilder = " + str); } } Output: StringBuilder = GeeksforGeeks Modified StringBuilder = GeeksforGeeks, References: https://docs.oracle.com/javase/7/docs/api/java/lang/StringBuilder.html#appendCodePoint(int) Comment More infoAdvertise with us Next Article StringBuilder appendCodePoint() method in Java with Examples A AmanSingh2210 Follow Improve Article Tags : Java java-basics Java-Functions Java-StringBuilder Practice Tags : Java Similar Reads StringBuffer appendCodePoint() Method in Java with Examples appendCodePoint() method of StringBuffer class appends the string representation of the codePoint argument to this sequence for which we require pre-requisite knowledge of ASCII table as then only we will be able to perceive output why the specific literal is being appended as there is already an in 3 min read StringBuffer codePointAt() method in Java with Examples The codePointAt() method of StringBuffer class returns a character Unicode point at that index in sequence contained by StringBuffer.
