How to find length of a string array?

I am having a problem with the following lines where car is a String array which has not been initialized/has no elements.

String c         


        

Answer 1

As all the above answers have suggested it will throw a NullPointerException.

Please initialise it with some value(s) and then you can use the length property correctly. For example:

String[] str = { "plastic", "paper", "use", "throw" };
System.out.println("Length is:::" + str.length);

The array 'str' is now defined, and so it's length also has a defined value.
