Is there any way to find string lenght without using any inbuilt fuctions in java?

Question

I know there are various inbuilt functions, using which we can count string length like lastIndexOf(), by converting a string into a char array and counting iteration. There is a way in C programming for(i = 0; s[i] != '\0'; ++i); . how to count string length in java like in C mentioned above.

Update: Yes, there are these methods String.length(), String.toCharArray(). But if there are any other hard code way to find the string length.

Answer 1

Java is an object-oriented language, where instances are encapsulated, and you access instance properties by calling methods (or directly accessing fields, if they are exposed / not private).

In Java, String is a built-in class with instances and methods, other than in C, where a string is something like an array of characters without any encapsulation.

So, whatever you do with a String, you'll end up calling built-in methods of that class, e.g.:

• toCharArray() is a built-in method.
• charAt() is a built-in method.

So, use the straightforward String.length() method.
