好的，所以我必须在医院管理系统上制作一个程序，我必须记录病人，医生，预约..现在我已经让病人和医生记录使用物体和arraylist但我在分配特定的问题时遇到了问题根据病人的病情向病人求医..这就是我基本上做的事情： -
Appointment app1= new Appointment();
Patient ap2= new Patient();
Doctor ii2= new Doctor();
for(i=0;i<appointments.size();i++){
app1=appointments.get(i);
ap2=patient.get(i);
ii2=doctor.get(i);
if(ap2.getIllness()==1){
if(ii2.getDocspecialization()==1){
System.out.println("the patient "+ap2.getId()+" is appointed to "+ii2.getDocname());
System.out.println("Appointment of patient"+ap2.getId());
System.out.println(app1.toString());
}
}
if(ap2.getIllness()==2){
if(ii2.getDocspecialization()==2){
System.out.println("the patient "+ap2.getId()+" is appointed to "+ii2.getDocname());
System.out.println("Appointment of patient"+ap2.getId());
System.out.println(app1.toString());
}
}
if(ap2.getIllness()==3){
if(ii2.getDocspecialization()==3){
System.out.println("the patient "+ap2.getId()+" is appointed to "+ii2.getDocname());
System.out.println("Appointment of patient"+ap2.getId());
System.out.println(app1.toString());
}
}
if(ap2.getIllness()==4){
if(ii2.getDocspecialization()==4){
System.out.println("the patient "+ap2.getId()+" is appointed to "+ii2.getDocname());
System.out.println("Appointment of patient"+ap2.getId());
System.out.println(app1.toString());
}
}
if(ap2.getIllness()==5){
if(ii2.getDocspecialization()==5){
System.out.println("the patient "+ap2.getId()+" is appointed to "+ii2.getDocname());
System.out.println("Appointment of patient"+ap2.getId());
System.out.println(app1.toString());
}
}
if(ap2.getIllness()==6){
if(ii2.getDocspecialization()==6){
System.out.println("the patient "+ap2.getId()+" is appointed to "+ii2.getDocname());
System.out.println("Appointment of patient"+ap2.getId());
System.out.println(app1.toString());
}
}
}
我在这里犯的错误是什么？我有一份患者可以选择的疾病清单，这就是为什么我使用getillness（）== 1同样适用于医生.. 为了以防万一，我将展示我的整个计划......
