无法在Java中向循环中的列表添加对象

我试图将一个对象添加到循环中的列表中。当我打印对象时，它会显示正确的值。但是当我打印列表时，它会显示列表的最后一个元素，它的打印时间等于列表的大小

这是附加的代码

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);

}

}

此代码似乎没有问题，如何打印列表？如何覆盖CastironProject的toString方法？您能提供当前输出吗？这可能不是问题的原因，但我对列表的静态声明有点困惑。您是否将其声明为类成员？如果是这样，为什么？也许一开始只有一个对象。我只是有一种直觉：你能发布CastIronProjects类的代码吗？@Ray类中的静态成员而不是属性：？
