How to output random characters by their Unicode code

I'm trying to output Unicode characters in the range 9398, 10178.

import java.util.*;
public class Unicode {
    public static void main(String[] args) {
        Random rand_char = new Random();
        int number = 10178;
        int unicode = rand_char.nextInt(number) + 9398;
        char smile = (char)('\u' + r.nextInt(unicode));
        System.out.println(smile);

    }
}

There are problems with '\u' in creating the variable.How can I solve this so that the program can output random characters in the range?

No need for \u - just cast the numeric character code to char:

Random rand_char = new Random();
int number = 10178;
int unicode = rand_char.nextInt(number) + 9398;
char smile = (char)(unicode);
System.out.println(unicode);
System.out.println(smile);

Example output:

12564
