这是一个类,我想将它放在TreeMap中。
public class JobDefinition {
private static String jobDescription;
private static String datasetName;
private static String jobName;
private static String responsiblePerson;
public JobDefinition(String jobDesc, String dataSet, String jobName2, String person) {
jobDescription=jobDesc;
datasetName=dataSet;
jobName=jobName2;
responsiblePerson=person;
}
public String getJobDescription() {
return jobDescription;
}
public String getDatasetName() {
return datasetName;
}
public String getJobName() {
return jobName;
}
public String getResponsiblePerson() {
return responsiblePerson;
}
}
这里我使用POI库从Spreadsheet中获取值。 TreeMap使用整数作为上面类的Key和Object作为其值。
for (int rowCount = rowStartIndex+1; rowCount < rowEndIndex; rowCount++)
{
String jobDesc=spreadsheet.getRow(rowCount).getCell(0).toString();
String dataSet=spreadsheet.getRow(rowCount).getCell(1).toString();
String jobName=spreadsheet.getRow(rowCount).getCell(2).toString();
String person =spreadsheet.getRow(rowCount).getCell(3).toString();
if(!jobName.equals("N/A") && jobName!=""){
validJobCount++;
jobDefinitionInfo.put(validJobCount, new JobDefinition(jobDesc,dataSet,jobName,person));
}
}
for(Map.Entry<Integer,JobDefinition> entry : jobDefinitionInfo.entrySet()) {
System.out.println(entry.getKey()+"::"+entry.getValue().getJobDescription());
}
在Map中设置所有值时。我迭代它。我得到了正确的密钥,但是所有相应的值(它是JobDefinition类的一个对象)都是最后一个放置的值。
输出:
1::Monthly UPDTMEND File
2::Monthly UPDTMEND File
3::Monthly UPDTMEND File
4::Monthly UPDTMEND File
5::Monthly UPDTMEND File
6::Monthly UPDTMEND File
7::Monthly UPDTMEND File
8::Monthly UPDTMEND File
9::Monthly UPDTMEND File
10::Monthly UPDTMEND File
预期输出
1::VRSFEND - TRANSACTION SWEEP
2::XCTLOAD
3::CHEKDATE - TO IDENTIFY BACKDATED TRANSACTIONS
4::EDITALIVE
5::EDITB
6::PRICE LOAD
7::ACCTSIM - run manually
8::ACCTLIV - run manually by DVG
9::Check Sybase jobs
10::Monthly UPDTMEND File
我觉得实施有问题。请告诉我还应该添加什么才能使其正常运行。
答案 0 :(得分:0)
您在参数中使用static
。这意味着每次运行时都会被覆盖,这完全可以解释为什么你总是得到最后一个元素。
您需要更改为:
private String jobDescription;
private String datasetName;
private String jobName;
private String responsiblePerson;
