Negative string length

Question

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

Answer 1

No; string length is 0 (empty string, represented as "") or higher. And the empty string does not coincide with the null (in Java it is not called a null string ).

To better understand what null means in Java, you can check the following questions:

• Is null an object?
• Is null a java keyword?

Answer 2

No never.

length is an unsigned number; it cannot be negative.

the first answer to the question denies the second legitimacy of the question.
