gainUsing some of the concepts of information entropy, in a sample set, the more "chaotic" the classification of a sample, the more information entropy it has, the more impure the sample is, and the more "neat" a sample is, the less information entropy it has, the purer the sample. The classification of samples is [1,1,1,0] than [1,1,0,0] good, the former is more "neat", more pure. So, if a property is divided into more pure samples, then the more we tend to choose this property.D is a collecti

Dao. Processor is the core class of data object and persistence of Java object in multi-database multi-entity environment, its consumer
The law concludes as follows:
One, with entity binding;
For Dao.entity objects, can be compatible with ejb.entity settings. Typical ways to use entity compatibility are:
Processor Pro =processorfactory.getprocessorinstance (ENT);
Or:
Processor Pro =processor.getinstance (

to be the better choice;
It sounds a bit round, but there's an example that might be clear, for example:
We can list the things we do on our daily work day:
Go to work, meet, eat, sleep, etc
We can list the parts of the hospital where the ENT need to check people:
Eyes, nose, ears, mouth, etc
These can be enumerated, and each of the things we have to do in a different way;
Of course you can say:
