* the use of appendCodePoint() method of StringBuilder class
*/
public class StringBuilderAppendCodePointExample {
public static void main(String[] args) {
// initialize our StringBuilder
StringBuilder sb = new StringBuilder("test string : ");
// ask for user input
System.out.print("Enter a code point:");
Scanner s = new Scanner(System.in);
String input = s.nextLine();
s.close();
// convert the string input to integer
Integer codepoint = Integer.parseInt(input);
// append the codepoint to our StringBuilder
sb.appendCodePoint(codepoint);
// print the contents of our StringBuilder
System.out.println(sb);
}
}
