怎么样用java语句判断表已经存在

[江湖小虾米东方未明]

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

try 
{ 
Statement   stmt   =   connect.createStatement(); 
stmt.executeQuery( "select   count(*)   from   yourTable "); 

} 
catch(SQLException   e) 
{ 
      System.out.print( "not exits "+   e.getMessage()); 
}

//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;
    }

java.sql.Connection con = getYourConnection(); 
   
ResultSet rs  = con.getMetaData().getTables(null, null,  "yourTable", null );
  if (rs.next())  {
 //yourTable exist
  }else  {
 //yourTable not exist
 }
