Array Adapter Class
A Java array is handled as an object in COBOL. Therefore, an adapter class is
generated for each array attribute (element type and number of dimensions). This
section explains how Java arrays are mapped to COBOL classes.
Array class
Explanation
An adapter class corresponding to the array is generated when:
• An array is used as a parameter of a public constructor.
• The type of a public field (static or non-static) is an array.
• An array is used as a parameter or return value of a public method (static or
non-static).
Arrays whose attributes shown below match are associated with the same adapter
class:
• Array element type
• Number of dimensions
