What is the maximum string length in Java?
Created May 8, 2012
Chandra Patni Strings are represented as character array. Therefore, theoretical limit of String length is
java.lang.Integer.MAX_VALUE
. However, in most machines you will run out of memory before you could create such a big String.
I use java -Xms256m -Xmx384m MaxStringLength
to run the following code successfully. :)
public class MaxStringLength { public static void main(String args[]) { int len = Integer.MAX_VALUE/30; char ch[] = new char[len]; for(int i = 0; i < len; i++) { ch[i] = 'a'; } String s = new String(ch); System.out.println(s.length()); } }
