java - 如何将列表变量传递给构造函数/方法

Question

我是 Java 新手。当我创建类的对象时，我在传递作为构造函数定义的一部分的 List 变量时遇到问题

    public class Patient {

    private String patientfirstName;
    private String patientLastName;
    private List<String> allergyList;


     public Patient(String patientfirstName, String patientLastName, 
     List<String> allergyList) {
     this.patientfirstName = patientfirstName;
     this.patientLastName = patientLastName;
     this.allergyList = allergyList;
      }


     Patient patientobj = new Patient("sean","john","allegry1");

报错:“构造函数“Str,str,str”未定义。”

我需要有关如何消除过敏的帮助

Answer 1

你需要一个List<String>而不是单个 String , Arrays.asList(T...) 可能是最简单的解决方案:

Patient patientobj = new Patient("sean", "john", Arrays.asList("allergy1"));

如果你有更多的过敏症

Patient patientobj = new Patient("sean", "john", 
        Arrays.asList("allergy1", "allergy2"));
