ArrayList型の変数に要素を導入する

Question

メソッド（クラスの病院内）で患者名（ArrayListを使用）をリストアップする必要があります。コードを書き込もうとしましたが、スタックしました。まず、ArrayListに名前を追加する必要があると思いますが、私はそれらを表示する必要があると思います。しかし、どうすればいいですか？

class Hospital 
{ Patient p; 


class Patient 
{ 

private String name,adress; 
private int age,phoneNumber,securityNumber; 
private char sex; 

Patient(String name,char sex,String adress,int age,int 
phoneNumber,int securityNumber) 
{ 
this.name=name; 
this.adress=adress; 
this.age=age; 
this.sex=sex; 
this.phoneNumber=phoneNumber; 
this.securityNumber=securityNumber; 
} 

String getName() 
{ 
    return name; 
} 
void setName(String nam) 
{ 
name=nam; 
} 

void ShowListOfNames(List <Patient> pat) 
{ 
for(Patient h:pat) 
    System.out.println(h.getName()); 
    } 
} 


} 



public class Tarea23_1ago 
{ 
public static void main(String[] args) 
{ 
Scanner x=new Scanner(System.in); 
List <Patient> pat=new ArrayList <Patient>(); 
pat.add(new Patient("dan",'f',"nuyoo",12,2356445,001)); 
pat.add(new Patient("fredy",'m',"idk",34,34657,002)); 
pat.add(new Patient("dan",'m',"west",21,345546,003)); 



} 

Answer 1

// First of all, these data are of a patient, not of a hospital, so I renamed the class... 
public class Patient 
{ 
    private String name,address; 
    private int age, phoneNumber, securityNumber; 
    private char sex; 

    // No need a no-argument-constructor 
    public Patient(String name, char sex, String address, int age, int 
      phoneNumber, int securityNumber) 
    { 
     // Just to remember: Java generates a super() call even if you do not write it out 
     super(); 
     this.name = name; 
     this.address = address; 
     this.age = age; 
     this.sex = sex; 
     this.phoneNumber = phoneNumber; 
     this.securityNumber = securityNumber; 
    } 

    public String getName() { return name; } 
    public void setName(String name) { this.name=name; } 
} 

// Now comes the part that is about more patients. Could be named a hospital... 
public class Hospital 
{ 
    // A list of patents 
    private final List<Patient> patients = new ArrayList<>(); 

    // Prints out the names of the patents on the list 
    public void showListOfNames() 
    { 
     for(final Patient : this.patients) 
     { 
      System.out.println(patient.getName()); 
     } 
    } 

    // The main method. It does not have to be in a separated class... 
    public static void main(String[] args) 
    { 
     final Scanner x = new Scanner(System.in); // Still not in use... 
     final Hospital h = new Hospital(); // our hospital instance, with the list of patients 

     // Adding patents to the hospital's list 
     h.patients.add(new Patient("dan",'f',"nuyoo",12,2356445,001)); 
     h.patient.add(new Patient("fredy",'m',"idk",34,34657,002)); 
     h.patient.add(new Patient("dan",'m',"west",21,345546,003)); 

     // Printing out the names 
     showListOfNames(); 
    } 

}
