How long is a string stored in the string pool in Java?

In Java, a string placed in the String Pool is stored there as long as the class that loaded this pool exists, usually until the program terminates. The String Pool is a special area of memory where unique immutable string literals are stored to save memory and speed up string comparison. Strings in the pool live for the entire duration of the application's runtime if they are referenced, and are not garbage collected as long as they are in use.
