For Mysql -

Setting array is not possible in Mysql.

Instead of that you can form a query for (?,?,..) in the loop and same way for setting values.

String[] Parameter = { "user1", "Administrator" };
String query = "select * from userinfo where firstname in (";
String temp = "";

for(i = 0; i < Parameter.length; i++) {
  temp += ",?";
}

temp = temp.replaceFirst(",", "");
temp += ")";
query = query + temp;

PreparedStatement pst = conn.prepareStatement(query);

so query becomes

select * from userinfo where firstname in (?,?)

and pass values also using loop.

For Oracle -

ArrayDescriptor arrayDescriptor = ArrayDescriptor.createDescriptor("CHAR_ARRAY", conn);
String[] Parameter = { "user1", "Administrator" };
java.sql.Array sqlArray = new oracle.sql.ARRAY(arrayDescriptor, conn, content);
.
.
pstmt.setArray(1, sqlArray);
