Converts an array of bytes into an instance of class Class. Before the Class can be used it must be resolved.

This method assigns a default ProtectionDomain to the newly defined class. The ProtectionDomain is effectively granted the same set of permissions returned when java.security.Policy.getPermissions(java.security.CodeSource) is invoked. The default domain is created on the first invocation of defineClass, and re-used on subsequent invocations.

To assign a specific ProtectionDomain to the class, use the defineClass method that takes a ProtectionDomain as one of its arguments.

Parameters:

name     The expected binary name of the class, or null if not known

b     The bytes that make up the class data. The bytes in positions off through off+len-1 should have the format of a valid class file as defined by The Java™ Virtual Machine Specification.

off     The start offset in b of the class data

len     The length of the class data

Returns: The Class object that was created from the specified class data.

Exceptions:

ClassFormatError     If the data did not contain a valid class

IndexOutOfBoundsException     If either off or len is negative, or if off+len is greater than b.length.

SecurityException     If an attempt is made to add this class to a package that contains classes that were signed by a different set of certificates than this class (which is unsigned), or if name begins with "java.".

Since: 1.1

`name`		The expected binary name of the class, or `null` if not known
`b`		The bytes that make up the class data. The bytes in positions `off` through `off+len-1` should have the format of a valid class file as defined by The Java™ Virtual Machine Specification.
`off`		The start offset in `b` of the class data
`len`		The length of the class data

`ClassFormatError`		If the data did not contain a valid class
`IndexOutOfBoundsException`		If either `off` or `len` is negative, or if `off+len` is greater than `b.length`.
`SecurityException`		If an attempt is made to add this class to a package that contains classes that were signed by a different set of certificates than this class (which is unsigned), or if `name` begins with "`java.`".
