How to find length of a string array?

Question

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

In Java, we declare a String of arrays (eg. car) as

String []car;
String car[];

We create the array using new operator and by specifying its type:-

String []car=new String[];
String car[]=new String[];

This assigns a reference, to an array of Strings, to car. You can also create the array by initializing it:-

String []car={"Sedan","SUV","Hatchback","Convertible"};

Since you haven't initialized an array and you're trying to access it, a NullPointerException is thrown.
