StringBuffer appendCodePoint() Method in Java with Examples

Difficulty Level : Basic
Last Updated : 04 Dec, 2018

The java.lang.StringBuffer.appendCodePoint(int cp)is the method which appends the string representation of the codePoint argument to this sequence.

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 Value : The method returns this object after appending the string represented by the codepoint.

Examples :

Input: StringBuffer = Apple
       int cp = 65
Output: AppleA 

Input: StringBuffer = GeeksforGeeks
       int cp = 156
Output: GeeksforGeeks?

Explanation:
Because 65 is the ASCII value for 'A' and
156 is the ASCII value for '?'

Below programs illustrate the java.lang.StringBuffer.appendCodePoint(int cp) method:
Program 1:

// Java praogram to illustrate the 
// java.lang.StringBuffer.appendCodePoint(int cp) 
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        StringBuffer sbf = new StringBuffer("Geeksforgeeks"); 
        System.out.println("String buffer = " + sbf); 
  
        // Here it appends the CodePoint as 
        // String to the string buffer 
        sbf.appendCodePoint(65); 
        System.out.println("After appending CodePoint is = " + sbf); 
    } 
} 

Output:

String buffer = Geeksforgeeks
After appending CodePoint is = GeeksforgeeksA

Program 2:

// Java praogram to illustrate the 
// java.lang.StringBuffer.appendCodePoint(int cp) 
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        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

Program 3:

// Java praogram to illustrate the 
// java.lang.StringBuffer.appendCodePoint(int cp) 
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        StringBuffer sbf = new StringBuffer("Geeksforgeeks"); 
        System.out.println("String buffer = " + sbf); 
  
        // Here it appends the CodePoint as 
        // string to the string buffer 
        sbf.appendCodePoint(43); 
  
        System.out.println("After appending CodePoint is = " + sbf); 
    } 
} 

Output:

String buffer = Geeksforgeeks
After appending CodePoint is = Geeksforgeeks+
