java中如何把ResultSet的结果集转换成一个二维数组

首先你的用一个sql语句：select count() from customer 取到符合条件记录的数目；

String lSqlStr = "select count() from customer";
 …
 int lCount = rs.getInt(1);
 String[][] lRecordArr = new String[lCount][3];
 //其中3是你的字段数customerID,customerName,customerInfString selectCustomer=select customerID,customerName,customerInf form customer;
 …
 rs=st.executeQuery(selectCustomer);
 int i=0;
 while(rs.next())
 {
 lRecordArr[i][0] = rs.getString(“customerID”);
 lRecordArr[i][1] = rs.getString(“customerName”);
 lRecordArr[i][2] = rs.getString(“customerInf”);
 i++
 }
