classFind

public static Class<?> classFind(String name)

Looks up a class by name. In contrast to Class.forName, primitive classes are found and not found is indicated by null.

Parameters:

name - the name of the Class to be found

Returns:

the Class found, null if nothing was found

Gets the common base of two classes. Common base is the most special class both argument are assignable to. The common base for different primitive types is null; the common base for a primitive type and a reference type is null.

Parameters:

a - first class, may be null

b - second class

Returns:

the common base; b, if a == null;
