例如,我已经创建了一个"事件列表"来自服务门户网站:
List<Incident> incidentObjectList = new ArrayList<>();
for (int i = 0; i < incidentNumberList.size(); i++) {
Incident incident = new Incident();
incident.setIncidentNumber(incidentNumberList.get(i));
incident.setSummary(summaryList.get(i));
incident.setRequestId(requestIdList.get(i));
incident.setPriority(priorityList.get(i));
incident.setLastModifiedDate(lastModifiedDateList.get(i));
incidentObjectList.add(incident);
}
System.out.println("Incident Object List" + incidentObjectList);
每个突发事件都有几个属性,但我只希望从原始列表创建一个新列表,该列表由优先级为Low
的突发事件对象组成。在这种情况下,incident.getPriority()
将为新列表中的所有对象返回字符串Low
。
String[] dataGreenArray = incidentObjectList.get();
retrieveTickets(dataGreenArray, listViewGreen);

在Java 8中
List<Incident> list = incidentObjectList.stream()
.filter(e->e.getPriorty().equals("Low"))
.collect(Collectors.toList());
答案 1 :(得分:2)
循环遍历incidentObjectList
并检查每个元素的优先级。
for (Incident incident: incidentObjectList)
{
if (incident.getPriority().equals("Low")
desiredList.add(incident); // or whatever you want to do
}
这是一个非常基本的解决方案,但除非您专门寻找其他内容,否则它应该有效。希望它有所帮助!
