RNGCryptoServiceProvider in Java

I'm converting some C# code to Java. I can't find an equivalent to RNGCryptoServiceProvider. How do I do this?

private static String GetRandomSalt()
{
    RNGCryptoServiceProvider random = new RNGCryptoServiceProvider();
    byte[] salt = new byte[32]; //256 bits
    random.GetBytes(salt);
    ...
}
