• a classname
• or a descriptor
• or an (object or array) type (for static fields)
• or a non-array object (for static and non-static fields)
• or an array (for 'length' pseudo field, or indexed element retrieval)

Fspec can be

• an atomic field name
• or an integral array index (to get an element from an array)
• or a pair I-J of integers (to get a subrange of an array).

Finally, an attempt will be made to unify V with the retrieved value or object reference.

Examples

jpl_get('java.awt.Cursor', 'NE_RESIZE_CURSOR', Q).
Q = 7.

jpl_new(array(class([java,lang],['String'])), [for,while,do,if,then,else,try,catch,finally], A),
jpl_get(A, 3-5, B).
B = [if, then, else].
