what is the length limit of String literal?

[Guoqiao Sun]

Hi, all, if I define a String like this:

String str = "Java";

Is there any lengh limitation for the String str? In other word, can I define a very very long String using this method?
Thanks in advance!

Guoqiao,
I read an old post on it a few months earlier (i can't remeber where )....and the folks concluded that Strings have no limits in size and only JRE considerations will act as a limitation (like ur RAM/virutal memory shortage causing a large heap to maintain)....etc....but i m not sure anyway!
But in sense it tells that a java object can contain a lot info virtually without any limitation...so a string object is a java object...

In the class file tha table CONSTANT_Utf8_info represents the information of the String literals, and several kinds of names: types, members, descriptors and attributes.
Given that the format of a CONSTANT_Utf8_info table has only two unsinged bytes for the length of the bytes representing the information of a String literal, I think the maximum size of a String literal, written as code, is 16536.
Yes, a String literal could be made to grow more than that via a for sentence, but doing so would not spawn an entry in the class file that exceedes the limit of the CONSTANT_Utf8_info table.
