无法在Java循环中将对象添加到列表中

Question

我试图将一个对象添加到循环内的列表中。当我打印对象时，它显示正确的值。但是当我打印列表时，它会显示列表的最后一个元素，它打印的时间数等于列表的大小。

这是附带的代码。

static List<CastIronProjects> allProjDetails;

allProjDetails = new ArrayList<CastIronProjects>();

// Connect to DB and querying the table
stmt = conn.createStatement();
String query = "SELECT * FROM CASTIRONPROJECTS";
rs = stmt.executeQuery(query);

// Extract data from the resultset
while(rs.next())
{
    CastIronProjects projDetails = new CastIronProjects();

    projDetails.setEmailAddress(rs.getString("EMAILADDRESS"));
    projDetails.setFrequency(rs.getString("FREQUENCY"));
    projDetails.setLastSuccessfulEndTime(rs.getDate("LASTSUCCESSFULENDTIME"));
    projDetails.setLastSuccessfulRunTime(rs.getDate("LASTSUCCESFULSTARTTIME"));
    projDetails.setMaxRunningTime(rs.getLong("MAXRUNNINGTIME"));
    projDetails.setOrchName(rs.getString("ORCHESTRATIONNAME"));
    projDetails.setOrchType(rs.getString("ORCHESTRATIONTYPE"));
    projDetails.setProjId(rs.getString("PROJECTID"));
    projDetails.setProjName(rs.getString("PROJECTNAME"));
    projDetails.setProjOwner(rs.getString("PROJECTOWNER"));
    projDetails.setRunsEvery(rs.getInt("RUNSEVERY"));
    projDetails.setVersion(rs.getFloat("VERSION"));

    allProjDetails.add(projDetails);

}

你能帮帮我吗？
