Array of Vectors

Perhaps this sounds a bit strange, but I think I have a pretty good reason for doing this. I intentionally want to make an array of vectors. Quite frankly, I don't like seeing warnings in my compiler output. So, I'm wondering what I can do about this. I also haven't tested this code to see if it actually works, but I don't see an issue with it.

Declaration:

Vector<Integer> uids =null;

Vector<BackupEntry>[] entries =null;

Initialization (just trust me that uids is initialized correctly):

// Okay we have a list of UIDs. Make the array

entries =new Vector[uids.size()];

// Init each one

for (int i = 0; i < entries.length; i++)

entries[i] =new Vector<BackupEntry>();

This code, however, results in the following warning (with Xlint:unchecked)

Compiling 30 source files to C:\wowiupdater\build\classes

C:\wowiupdater\src\wowiupdater\ReversionDialog.java:62: warning: [unchecked] unchecked conversion

found: java.util.Vector[]

required: java.util.Vector<wowiupdater.BackupEntry>[]

entries = new Vector[uids.size()];

1 warning

Now, I can seewhy it doesn't like this -- because the initialization code doesn't specify what it is a vector of. But, as you can see later in the code, we're certain to be making vectors of BackupEntrys. So I tried this:

entries =new Vector<BackupEntry>[uids.size()];

But that just results in the following complaint:

Compiling 30 source files to C:\wowiupdater\build\classes

C:\wowiupdater\src\wowiupdater\ReversionDialog.java:62: generic array creation

entries = new Vector<BackupEntry>[uids.size()];

1 error

BUILD FAILED (total time: 0 seconds)

So do I have any way around this warning, or do I just have to ignore it? (Or is there a better way I should be going about this?)

Regards,
