Ans. You can't represent something that will print as N zeros using a single character, or as an array consisting of a single character.

You need to use an alternative representation. The most obvious ideas are:

Use a character array with multiple characters, using one character slot for each zero. (You still won't be able to print a char[] directly using println ... but there are other ways to do it.)
Use a String, or a StringBuilder to represent the sequence of zeros.
