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 integer value been assigned.
--> appendCodePoint() Method
--> StringBuffer Class
--> java.lang Package
Syntax:
public StringBuffer appendCodePoint(int cp)
Parameters: The method accepts a single parameter cp of integer type and refers to the Unicode code point.
Return Type: The method returns this object after appending the string represented by the codepoint.
Illustrations:
Input : StringBuffer = Apple
int cp = 65
Output: AppleA
Input : StringBuffer = Lazyroar
int cp = 156
Output: Lazyroar?
Explanation: Because 65 is the ASCII value for ‘A’ and 156 is the ASCII value for ‘?’
Example 1:
Java
// Java program to illustrate appendCodePoint() Method// of StringBuffer class// Importing required classesimport java.lang.*;// Main classpublic class GFG { // Main drive method public static void main(String[] args) { // Reading passed string StringBuffer sbf = new StringBuffer("Geeksforgeeks"); // Printing the string System.out.println("String buffer = " + sbf); // Appending the CodePoint as String to the string // buffer sbf.appendCodePoint(65); // Printing the string again after // appending codePoint as string System.out.println("After appending CodePoint is = " + sbf); }} |
Output:
String buffer = Geeksforgeeks After appending CodePoint is = GeeksforgeeksA
Example 2:
Java
// Java Program to Illustrate appendCodePoint() Method// of StringBuffer class// Importing required classesimport java.lang.*;// Main classpublic class GFG { // Main driver method public static void main(String[] args) { // Reading passed string by creating object of class StringBuffer sbf = new StringBuffer("Geeksforgeeks"); System.out.println("String buffer = " + sbf); // Here it appends the CodePoint as // string to the string buffer sbf.appendCodePoint(54); System.out.println("After appending CodePoint is = " + sbf); }} |
Output:
String buffer = Geeksforgeeks After appending CodePoint is = Geeksforgeeks6
Example 3:
Java
// Java program to illustrate appendCodePoint() Method// of StringBuffer class// Importing required classesimport java.lang.*;// Main classpublic class GFG { // Main driver method public static void main(String[] args) { // Reading passed string StringBuffer sbf = new StringBuffer("Geeksforgeeks"); // Printing string on console System.out.println("String buffer = " + sbf); // Appending the codePoint as string // to the string buffer sbf.appendCodePoint(43); // Printing the string on console after // appending codepoint as string System.out.println("After appending CodePoint is = " + sbf); }} |
Output:
String buffer = Geeksforgeeks After appending CodePoint is = Geeksforgeeks+
