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。
语法 ：
public StringBuffer appendCodePoint(int cp)参数：该方法接受整数类型的单个参数cp，并引用Unicode代码。
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 ：
输入：
输入: StringBuffer = Apple
int cp = 65
输出: AppleA
输入: StringBuffer = 芒果文档
int cp = 156
输出: 芒果文档?
说明：
因为65是'A'的ASCII值，
156是'？'的ASCII值下面的程序说明了java.lang.StringBuffer.appendCodePoint(int cp)方法： 程序1：
// Java程序，展示java.lang.StringBuffer.appendCodePoint(int cp)
import java.lang.*;
public class 芒果 {
public static void main(String[] args)
{
StringBuffer sbf = new StringBuffer("芒果文档");
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 = 芒果文档
After appending CodePoint is = 芒果文档A程式2：
// Java程序，展示java.lang.StringBuffer.appendCodePoint(int cp)
import java.lang.*;
public class 芒果 {
public static void main(String[] args)
{
StringBuffer sbf = new StringBuffer("芒果文档");
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 = 芒果文档
After appending CodePoint is = 芒果文档6程式3：
// Java程序，展示java.lang.StringBuffer.appendCodePoint(int cp)
import java.lang.*;
public class 芒果 {
public static void main(String[] args)
{
StringBuffer sbf = new StringBuffer("芒果文档");
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 = 芒果文档
After appending CodePoint is = 芒果文档+
