What methods can be used for the reachability of data with the Java Beans?

The JavaBeans have properties to describe the data within them and to determine the expected behavior. JavaBeans in the variables are not accessible to users own private or protected type, because you must be reachable using public methods.

1. public void setNome_Proprietà (): takes as parameters the type of data, the properties and their value.
2. public property_type getNome_Proprietà (): detects the information on the property.
3. public boolean isNome_Proprietà (): also collects information on the property.
