VB实现的Com对象如下
VERSION 1.0 CLASS BEGIN MultiUse = -1 'True Persistable = 0 'NotPersistable DataBindingBehavior = 0 'vbNone DataSourceBehavior = 0 'vbNone MTSTransactionMode = 0 'NotAnMTSObject END Attribute VB_Name = "MyCOM" Attribute VB_GlobalNameSpace = False Attribute VB_Creatable = True Attribute VB_PredeclaredId = False Attribute VB_Exposed = True Public Sub Test(ByRef param() As String) ReDim param(2) param(0) = "Hello" param(1) = "World" End Sub
编译执行Exam_6.java 打印 Hello World
