Java wrapper around Map-like implementation

I'm looking for a stable and user-friendly wrapper implementation around the Java Map interface. Basically, I would like to use the Android Bundle functionality so that I can do this:

float getFloat(String key, float defaultValue)


void putShort(String key, short value)


String getString(String key, String defaultValue)


void putInt(String key, int value)

etc. I've seen the ResourceBundle class, but I would like more methods than getObject

that getString

.

Are there any other alternatives?
