敏捷开发中如何将注释转换为代码

public class ParticipantInfoOnBadge {
...
void getOrgNameAndCountry() {
OrganizationsInDB orgsInDB = OrganizationsInDB.getInstance();
String oid = orgsInDB.findOrganizationEmploying(participantId);
if (oid != null) {
Organization org = orgsInDB.locateOrganization(oid);
engOrgName = org.getEName();
chiOrgName = org.getCName();
engOrgCountry = org.getEAddress().getCountry();
chiOrgCountry = org.getCAddress().getCountry();
}
}
}
public class OrganizationsInDB {
...
void findOrganizationEmploying(String participantId) {
...
}
}

　　改进完的代码

　　看看改进完的代码，如果让其他人读我们的代码，现在看懂需要多长时间？而重构之前，那个人又需要花多长时间？

public class ParticipantInfoOnBadge {
String participantId;
String participantEngFullName;
String participantChiFullName;
String engOrgName;
String chiOrgName;
String engOrgCountry;
String chiOrgCountry;
ParticipantInfoOnBadge(String participantId) {
loadInfoFromDB(participantId);
}
void loadInfoFromDB(String participantId) {
this.participantId = participantId;
getParticipantFullNames();
getOrgNameAndCountry();
}
void getParticipantFullNames() {
ParticipantsInDB partsInDB = ParticipantsInDB.getInstance();
Participant part = partsInDB.locateParticipant(participantId);
if (part != null) {
participantEngFullName = part.getEFullName();
participantChiFullName = part.getCFullName();
}
}
void getOrgNameAndCountry() {
OrganizationsInDB orgsInDB = OrganizationsInDB.getInstance();
String oid = orgsInDB.findOrganizationEmploying(participantId);
if (oid != null) {
Organization org = orgsInDB.locateOrganization(oid);
engOrgName = org.getEName();
chiOrgName = org.getCName();
engOrgCountry = org.getEAddress().getCountry();
chiOrgCountry = org.getCAddress().getCountry();
}
}
}

　　为什么要删除额外的注释？
