Negative String Length

Question

Can you have a negative string length? If so, is it the same as null?

Answer 1

No; the length of a string is 0 (empty string, represented as "") or higher. And an empty string is not the same as null either (in Java it is not called a null string).

To better understand what null means in Java, you could check out these questions:

• Is null an Object?
• Is null a Java keyword?

Answer 2

No, never.

length is unsigned number, it can't be negative.

the first question's answer negates the second question's legitimacy.
