appendCodePoint (int codePoint)

public synchronized StringBuffer appendCodePoint(int codePoint)

Appends the string representation of the codePoint argument to this sequence. The length of this sequence increases by Character.charCount(codePoint).

public class StringBufferAppendCodePoint {
    public static void main(String args[]){
        StringBuffer s1 = new StringBuffer("Value of s1 is ");
        s1.appendCodePoint(63);
        
        System.out.println("s1 = " + s1);
    }
}
