十三爷胤祥扮演者王辉:java中怎样得到数据库数据条数

如题,怎样得到数据条数
下面是连接代码
public boolean setAccessConnection(String dbFile) {
//连接Access数据库
boolean result = false;
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String dbUrl =
"jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=" +
dbFile;
conn = DriverManager.getConnection(dbUrl);
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
System.out.println("数据库连接成功");
result = true;
} catch (SQLException ex) {
System.out.println(ex.getMessage());
result = false;
} catch (Exception e) {
System.out.println(e.getMessage());
result = false;
}
return result;
}
