Number of Characters in Java String

0 votes

I was working on a code where I am supposed to find the palindrome for an integer of up to a million digits. To make my task easy, I was thinking of using the String reverse function. But I have a doubt regarding the max length of the String that Java allows. Have anyone any idea regarding this?

I think you can make use of either of the following to know the max length of String you can use:

  1. Integer.MAX_VALUE (always 2147483647 (231 - 1).​
  2. Half of your maximum heap size as each character is two bytes
