Java JSR

Suggested improvements for the java langage

This page contains several improvements suggested for the java langage - my favorite programmind and thinking langage.

They would possibly be translated into JSRs, if this is not too complex and dissuasive.

Together, they describe the langage that would have loved to use...

Fuzzy primitive type

Besides the existing primitive types, it is suggested to add the fuzzy type, which may be consisdered as a mix of boolean and real value.

A fuzzy varaible would be used to represent fuzzy logic values, probabilities, ad generally speaking real values in the [0.0,1.0] range. Example of computing and mathematics concepts are : saturation levels, permeabilities, similarities, etc...  

The fuzzy type should be involves in various casting process

• fuzzy -> boolean
• boolean -> fuzzy
• real (double or float) -> fuzzy
• fuzzy -> real (double or float)

Fuzyy variable should then be usable wherever boolean vars are used, like in if and while statements.

The displayed value (toString()) of a fuzzy var may be true, false or a real value between (excluding) 0.0 and 1.0 ;  true is a short form of 1.0 , false is a short form of 0.0. 

Operations on fuzzy variable should include

• not (!x) :   !x == (fuzzy)(1.0-(real)x)
• and (x&&y) :  x&&y == (fuzzy)(real)x * (real)y)
• and (x^^y) :  x&&y == (fuzzy)(real)x * (real)y)
• or (x||y) : 
• real-derived operations + - * / (with the restriction that the result is transformed into 1.0 (true) if it exceeds 1.0, and into 0.0 (false) if it falls below 0.0.
