Java StringBuffer appendCodePoint()用法及代码示例

java.lang.StringBuffer.appendCodePoint(int cp)是将codePoint参数的字符串表示形式附加到此序列的方法。

用法:

public StringBuffer appendCodePoint(int cp)

参数：该方法接受整数类型的单个参数cp，表示Unicode代码点。

返回值：该方法在附加由代码点表示的字符串之后返回此对象。

例子：

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 '?'

以下示例程序旨在说明java.lang.StringBuffer.appendCodePoint(int cp)方法：
示例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); 
    } 
}

输出：

String buffer = Geeksforgeeks
After appending CodePoint is = GeeksforgeeksA

示例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); 
    } 
}

输出：

String buffer = Geeksforgeeks
After appending CodePoint is = Geeksforgeeks6

示例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); 
    } 
}

输出：

String buffer = Geeksforgeeks
After appending CodePoint is = Geeksforgeeks+
