客户信息管理软件

作者:互联网

代码包含四个类:BankUtility类用于控制键盘输入输出的准确性,Customer类封装客户个人信息,CustomerList类对客户信息进行增删改查的操作,CustomerView类为主类显示界面和菜单。

用户类:

package newbank;

public class Customer {
	private String name;
	private String sex;
	private String phonenumber;
	private String email;
	
	Customer(){
		
	}
	Customer(String name,String sex,String phonenumber,String email){
		this.name = name;
		this.sex = sex;
		this.phonenumber = phonenumber;
		this.email = email;
	}
	public void setName(String name) {
		if(name != "")
			this.name = name;
	}
	public String getName() {
			return name;
	}
	public void setSex(String sex) {
		if(sex != "")
			this.sex = sex;
	}
	public String getSex() {
		return sex;
	}
	public void setPhoneNumber(String phonenumber) {
		if(phonenumber != "")
			this.phonenumber = phonenumber;
	}
	public String getPhoneNumber() {
		return phonenumber;
	}
	public void setEmail(String email) {
		if(email != "")	
			this.email = email;
	}
	public String getEmail() {
		return email;
	}
}

主界面:

package newbank;
import java.util.Scanner;

public class CustomerView {

	public static void main(String[] args) {
		int choice;
		CustomerList a = new CustomerList();
		boolean isflag = true;
		while(isflag) {
			System.out.println("-------------客户信息管理软件-------------");
			System.out.println("             1. 添加客户");
			System.out.println("             2. 修改客户");
			System.out.println("             3. 删除客户");
			System.out.println("             4. 客户列表");
			System.out.println("             5. 退    出");
			System.out.print("             请选择(1-4): ");
			choice = BankUtility.readChoice();
			System.out.println();
			switch (choice) {
			case '1' :
				a.addNewCustomer();
				break;
			case '2' :
				a.changeCustomer();
				break;
			case '3' :
				a.deleteCustomer();
				break;
			case '4' :
				a.showCustomer();
				break;
			case '5' :
				System.out.print("你确定要退出吗(Y/N): ");
				char isExit = BankUtility.readSeletion();
				if(isExit == 'Y')
					isflag = false;
			}
		}
		
	}

}

 运行效果:

 各方法的实现:

1. 添加客户

public void addNewCustomer() {
		customer[customernumber] = new Customer();
		System.out.println("---------------添加客户----------------");
		System.out.print("姓名: ");
		customer[customernumber].setName(BankUtility.readName());
		System.out.println();
		System.out.print("性别: ");
		customer[customernumber].setSex(BankUtility.readSex());
		System.out.println();
		System.out.print("电话号码: ");
		customer[customernumber].setPhoneNumber(BankUtility.readPhoneNumber());
		System.out.println();
		System.out.print("邮箱: ");
		customer[customernumber].setEmail(BankUtility.readEmail());
		System.out.println();
		System.out.println("---------------添加完成----------------");
		System.out.println();
		customernumber++;
	}

2.修改用户信息

 

public void changeCustomer() {
		System.out.println("---------------修改客户----------------");
		System.out.print("请选择要修改的客户编号(输入-1退出): ");
		int number = BankUtility.readCustomerNumber();
		while(number != -1){
			if(number > 0 && number <= customernumber - 1) {
				System.out.print("(姓名)" + customer[number].getName() +": ");
				customer[number].setName(BankUtility.readName());
				System.out.println();
				System.out.print("(性别)" + customer[number].getSex() + ": ");
				customer[number].setSex(BankUtility.readSex());
				System.out.println();
				System.out.print("(电话号码)" + customer[number].getPhoneNumber() + ": ");
				customer[number].setPhoneNumber(BankUtility.readPhoneNumber());
				System.out.println();
				System.out.print("(邮箱)" + customer[number].getEmail() + ": ");
				customer[number].setEmail(BankUtility.readEmail());
				break;
			}
			else {
				System.out.println("无法找到指定用户!");
				System.out.print("请重新输入:");
				number = BankUtility.readCustomerNumber();
			}
		};
		System.out.println("---------------修改完成----------------");
		System.out.println();

	}

3.删除用户

public void deleteCustomer() {
		System.out.println("---------------删除客户----------------");
		System.out.print("请选择你要删除的用户(输入-1退出): ");
		int number = BankUtility.readCustomerNumber();
		while(number != -1){
			if(number > 0 && number <= customernumber - 1) {
				System.out.print("你确定要删除用户吗(Y/N): ");
				char c = BankUtility.readSeletion();
				if(c == 'Y') {
					for(int i = number;i < customernumber;i++) {
						customer[i] = customer[i+1];
						}
					customernumber--;
					System.out.println("---------------删除成功----------------");
				}
				break;
			}
			else {
				System.out.println("无法找到指定用户!");
				System.out.print("请选择你要删除的用户(输入-1退出): ");
				number = BankUtility.readCustomerNumber();
			}
			};
		System.out.println();
	}

 

 4.显示所有用户

public void showCustomer() {
		System.out.println("---------------客户列表----------------");
		System.out.println();
		System.out.println("编号\t\t姓名\t\t性别\t\t电话号码\t\t邮箱");
		for(int i = 1;i < customernumber;i++) {
			System.out.println(i + "\t\t" + customer[i].getName() +  "\t\t" + customer[i].getSex() + "\t\t" + customer[i].getPhoneNumber() + "\t" + customer[i].getEmail());
		}
		System.out.println();
	}
