如何样用java语句判断表已经存在

怎么样用java语句判断表已经存在
最近在写一个程序，需要操作数据库的表之前，先探查是否存在该表否则就建立该表，请问在程序中如何来判断，是用resultset结果集吗？

为更形象的表述，我贴一下代码：
  Connection con=DriverManager.getConnection(conURL);
Statement s=con.createStatement();
  if(VIP表不存在）
  {
String r1="create table "+r2+"(" +
"name varchar(20) not null," +
"sex char(1) not null," +
"telephone varchar(20)," +
"officephone varchar(20)," +
"Email varchar(20)," +
"suoying integer primary key)";
s.executeUpdate(r1);
  }
求问怎么写试探该VIP表不存在的

Java code

try { Statement   stmt   =   connect.createStatement(); stmt.executeQuery( "select   count(*)   from   yourTable "); } catch(SQLException   e) {       System.out.print( "not exits "+   e.getMessage()); }

Java code
//name 表名 public boolean HasTable(String name) {        //判断某一个表是否存在        boolean result = false;        try {            DatabaseMetaData meta = sqlConn.getMetaData();//sqlConn 数据库连接            ResultSet set = meta.getTables (null, null, name, null);            while (set.next()) {                result = true;            }        } catch (Exception e) {            System.err.println(e);            e.printStackTrace ();        }        return result;    }
