Heh, as if Java's string was mundane, or even particularly well standardised. The implementation for String have varied in each of the JVM versions, and Android has a different version to the JDK. Java's string, depending on the string, length, JVM version and a bunch of other factors may or may not: - Be interned - so the result of "str1" == "str1" is compiler dependant (you must do "str1".equals("str1")). - Maintain references to the string when doing a substring - e.g. "Java is a language full of quirks......".substring(0,4) may or may not hold a reference to the entire string. This has huge performance tradeoffs - e.g. if you parse JSON by doing .substring(), and aren't careful, then you can end up holding onto the entire unparsed JSON, even if you only keep track of a single obejct.
