while(result.next()) 
{ 

vectordata=new Vector(); 
vectordata.addElement(result.getString(1)); 
vectordata.addElement(result.getString(2)); 
vectordata.addElement(result.getString(3)); 
vectordata.addElement(result.getString(4)); 
vectordata.addElement(result.getString(5)); 
vectordata.addElement(result.getString(6)); 
vectordata.addElement(result.getString(7)); 

max.addElement(vectordata); 

}

由于while时就使用了next所以使终无法读到第一条记录，请帮忙解决谢谢

刚才的回答错了。
看ResultSet的doc：
Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.
第一次调用next()，指向的就是第一个元素。
