Sharing data with Java

Share data items with Java in these ways:

• Pass them as arguments in the USING phrase of an INVOKE statement.
• Receive them as parameters in the USING phrase from a Java method.
• Receive them as the RETURNING value in an INVOKE statement.
• Return them as the value in the RETURNING phrase of the PROCEDURE DIVISION header in a COBOL method.

To pass or receive arrays and strings, declare them as object references:

• Declare an array as an object reference that contains an instance of one of the special array classes.
• Declare a string as an object reference that contains an instance of the jstring class.
