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
