Nested Class Declarations A class can be declared within the scope of another class. Such a class is called a “nested class.” Nested classes are considered to be within the scope of the enclosing class and are available for use within that scope. To refer to a nested class from a scope...
1.Is there a tidy name for this technique (analogous to inner, nested, anonymous)? Multi-class single-file demo. 2.The JLS says the system may enforce the restriction that these secondary classes can't be referred to by code in other compilation units of the package, e.g., they can'...
An interface can contain declarations for functions, events, and properties. All interface members have public accessibility. An interface can also contain static data members, functions, events, and properties, and these static members must be defined in the interface. ...
The classes and interfaces which belong to a nest, including its host, are determined when class files are generated, for example, a Java compiler will typically record a top-level class as the host of a nest where the other members are the classes and interfaces whose declarations are ...

Packages, and consequently their members, have names in a hierarchical name space; the Internet domain name system can usually be used to form unique package names. Compilation units contain declarations of the classes and interfaces that are members of a given package, and may import classes and...
Consensus clustering (CC) has been adopted for unsupervised class discovery in many genomic studies. It calculates how frequently two samples are grouped together in repeated clustering runs and uses the resulting pairwise "consensus rates" for visual de
