UCAExc:::3.0.7意外标记:logDate

大家好。我正在做一个个人项目,需要与ms access 2016数据库交互。我的java应用程序从用户获取数据,这些信息存储在对象[]中。我试图将obj数组的元素插入数据库中的表中。这是我的代码:

Connection conn = null;
PreparedStatement pstmnt = null;
String sql = null;
ResultSetMetaData md = null;
Statement stm = null;
ResultSet rs = null;
int i = 0;
String q = "SELECT * from QueryData";
try{
    conn = DriverManager.getConnection("jdbc:ucanaccess://filePath");
    stm = conn.createStatement();
    rs = stm.executeQuery(q);
    md = rs.getMetaData();
    int count = md.getColumnCount();
    String[] colName = new String[count];
    for (int n = 1; n <= count; n++)
        colName[n-1] = md.getColumnLabel(n);
    while ( i <= data.length) {//data being the object array containing the data to be inserted in db
        query = "INSERT into QueryData ('"+colName[i]+"') VALUES ('"+data[i]+"')";
            //The following code is where I get the exception
        pstmnt = conn.prepareStatement(query);
        //some more code follows..
