how to extract string and store to database using java

Question

ID | RECORDTYPE | RECORDNUMBER | SOURCESYSTEMID | TARGETSYSTEMID |

I have problem to extract this data and store it in array list and insert into database. Could you please help me?..

This is my code:-

public void massageData(String tmp) {
    String Id = "";
    String RecordType = "";
    String RecordNumber = "";
    String sourceSystemId = "";
    String targetSystemId = "";
    String TelNo = "";

    String[] recArray = tmp.split("\\|");

    RecordType = recArray[1].trim();
    RecordNumber = recArray[2].trim();
    sourceSystemId = recArray[3].trim();
    targetSystemId = recArray[4].trim();
    TelNo = recArray[5].trim();

    Connection conn = null;
    ResultSet rs = null;
    PreparedStatement stmt = null;

    String actualMSISDN = parseMSISDN(TelNo);

    String iCtr = getiCtr(actualMSISDN);
    Id = recArray[0].trim();
    String stateCode = lookupStateCode(State);
    try {
        conn = ds.getConnection();
        // insert post process data to data_999 table
        String sQuery = "insert into DATA_999 (ID,RecordType,RecordNumber,SourceSystemApplicationId,TargetApplicationId,TelNo) values(?,?,?,?,?,?)";

        stmt = conn.prepareStatement(sQuery);
        int dbStat = stmt.executeUpdate();
        int isExist = chkMsisdn(actualMSISDN);
        if(isExist > 0) {
            // retrieve record from database
            icData oldData = getRecord(actualMSISDN);

            icData newData = new icData();
            stmt.setString(1, Id);
            stmt.setString(2, RecordType);
            stmt.setString(3, RecordNumber);
            stmt.setString(4, sourceSystemId);
            stmt.setString(5, targetSystemId);
            stmt.setString(6, TelNo);
        }
        conn.close();
    } catch(SQLException s) {
        logger.error(s.getMessage());
    } finally {
        try {
            if(stmt != null) stmt.close();
        } catch(SQLException e) {
        }
        try {
            if(conn != null) conn.close();
        } catch(SQLException e) {
        }
    }
}

在设置参数（ stmt.setString() ）之前，您似乎正在执行语句（ stmt.executeUpdate() stmt.setString() ）。
