Java String is absolutely immutable?

[tashirosgt]

From looking at the documentation for java.lang.String, I see no way to change the contents of a String. The methods that deal with concatenation etc. return Strings that are presumably different objects than the original one. Do any of the other java packages have the ability to change the characters within a string if the total number of characters is not changed?

Use StringBuffer or StringBuilder if you want a mutable String.
