Question

我已经创建了一个正常运行的控制台菜单，我将选择添加新客户的选项，如下所示我创建了扫描仪以输入详细信息，我不知道如何保存用户输入到名为CustomerInformation的文本文件。我可以使用此方法的函数执行此操作，或者在退出控制台菜单之前有一些方法来存储信息并创建保存功能。

    public void addCustomer()
    {
    Scanner sc = new Scanner(System.in);
    System.out.print("Enter Name: ");
    this.name = sc.nextLine();
    System.out.print("Enter Address: ");
    this.address = sc.nextLine();
    System.out.print("Enter Gender(M or F): ");
    this.gender = sc.nextLine();
    System.out.print("Enter Date of Birth: ");
    this.dob = sc.nextLine();
    }

整个客户类是：

import java.util.*;
import java.io.*;

public class Customer {

private String name;
private String address;
private String gender;
private String dob;

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}
public String getGender() {
    return gender;
}
public void setGender(String gender) {
    this.gender = gender;
}
public String getDob() {
    return dob;
}
public void setDob(String dob) {
    this.dob = dob;
}

Customer (){

    setName("Name");
    setAddress("Address");
    setGender("Gender");
    setDob("dDob");
}

    Customer (String strName, String strAddress, String strGender, String strDob, String strReport){

    setName(strName);
    setAddress(strName);
    setGender(strGender);
    setDob(strDob);
}

    {
    Scanner sc = new Scanner(System.in);
    System.out.print("Enter Name: ");
    this.name = sc.nextLine();

    this.address = sc.nextLine();
    System.out.print("Enter Gender(M or F): ");
    this.gender = sc.nextLine();
    System.out.print("Enter Date of Birth: ");
    this.dob = sc.nextLine();
    }

    public static int nextInt()
    {
        Scanner keyb = new Scanner(System.in);
        int i = keyb.nextInt();
        return i;
    }

}

这是Test class.read writeCustomerToFile方法。这不难。我希望你能弄明白：

   public final class Test {

   public static void main(String[] args) {
       Customer customer = new Customer();

       Scanner sc = new Scanner(System.in);
       System.out.print("Enter Name: ");
       customer.setName(sc.nextLine());
       System.out.print("Enter Address: ");
       customer.setAddress(sc.nextLine());

       System.out.print("Enter Gender(M or F): ");
       customer.setGender(sc.nextLine());
       System.out.print("Enter Date of Birth: ");
       customer.setDob(sc.nextLine());

       writeCustomerToFile(customer,"D:/yourfilename.txt");

   }

   public static void writeCustomerToFile(Customer customer, String fileName) {

       PrintWriter writer = null;
    try {
        writer = new PrintWriter(fileName, "UTF-8");
        writer.println("name:" + customer.getName());
           writer.println("address:" + customer.getAddress());
           writer.println("gender:" + customer.getGender());
           writer.println("birth date:" + customer.getDob());

           writer.close();

       } catch (FileNotFoundException ex) {
           Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
       } catch (UnsupportedEncodingException ex) {
           Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
       } finally {
           writer.close();
       }
    }

  }
