How can I print unicode symbols within a certain range?

I am trying to make a program which prints all Unicode symbols \u6000 through \u7000(1000 symbols). My program prints 50 characters, starts a new line, prints 50 more, etc. (no issue there).

I know how to print Unicode symbols, but I am not sure how to print them incrementally (adding 1 each time). Here is my program:

public class UnicodePrinter {
    public static void main(String args[]) {
        for (int i = 6000; i<7000; i++) {
            if(i%50 == 0) {
                System.out.println();
            }
            System.out.print("\u"+i); //issue here, see below
        }
    }
}

I get an error on my print statement, where I typed "\u"+i saying "Invalid unicode" because \u is not completed with numbers, but I have no idea how to fix it.
