String CharAt Method Using Long

Question

I want to find a character in a specific position on a very large line. However, I cannot use the charAt() method because the range exceeds the value for int. Do you have such a setting?

Answer 1

In Java, strings have character array support. The theoretical size of the array is limited by the maximum int value, so it is impossible to create a string with more than 2 characters ³¹ -1.

To overcome this problem, you can create your own string class that uses multiple arrays or strings as storage.

Answer 2

Take only a shorter substring from a large string and get access to the corresponding position?

Answer 3

Since String is internally represented by an array of characters, its maximum length cannot be greater than the size of int. Therefore, in the first place, you cannot have a String exceeding the range of int.
