检查avl树

Question

我想从随机数组中插入一棵树。这是我的代码：

Private Sub UserForm_Initialize()
    With Me.cbxShipFrom
        .AddItem ("My Company")
        .AddItem ("Warehouse")
        .AddItem ("Warehouse 2")
        .AddItem ("Other...")
        If ActiveDocument.Bookmarks("shipfrom").Range.Text = "MY COMPANY" & Chr(13) & "123 BEETLE ST" & Chr(13) & "MYCITY, ST xZIPx" Then
            .Value = .List(0)
        End If
    End With
End Sub

然后我看到了这个警告：

int[] startValues=new int [100];
for(int i=0;i<startValues.length;i++){
startValues[i]=rnd.nextInt(10);
tree.insert(startValues[i]);

如何解决此问题？
