java实现电话本管理系统

用JAVA实现一个简单的电话本管理系统，能存储100个人的姓名、性别、年龄、电话等信息，并能对此系统进行增删改查的操作。

部分代码如下:

public class Phbook {
public static void main(String[] args) {
       Person personarray[] = new Person[100];
       int index = 0;
       for (int i = 0; i < 100; i++) {
          System.out.println("电话本管理系统");
          System.out.println("1.添加   2.删除   3.修改   4.查询所有   5.根据姓名查询   0.退出");
          System.out.println("请选择业务");
          Scanner input = new Scanner(System.in);
          int a = input.nextInt();
     switch (a) {
    case 0: {
      System.out.println("退出系统");
      i = 101;
    }
      ;
      break;
    case 1: {
      System.out.println("添加电话本");
      System.out.print("姓名：");
      Scanner n = new Scanner(System.in);
      String name = n.next();
      System.out.print("性别：");
      Scanner s = new Scanner(System.in);
      String sex = s.next();
      System.out.print("年龄：");
      Scanner ag = new Scanner(System.in);
      String age = ag.next();
      System.out.print("电话：");
      Scanner tel = new Scanner(System.in);
      String telnum = tel.next();
      System.out.print("qq：");
      Scanner q = new Scanner(System.in);
      String qq = q.next();
      System.out.print("地址：");
      Scanner add = new Scanner(System.in);
      String address = add.next();
      personarray[index] = new Person(name, sex, age, telnum, qq,
          address);
      index = index + 1;
    }
      ;
      break;
    case 2: {
      System.out.println("删除电话本");
      System.out.println("需要删除的姓名：");
      Scanner name0 = new Scanner(System.in);
      String namedel = name0.next();
      for (int j = 0; j < index; j++) {
        if (namedel.equals(personarray[j].name) == true) {
          for (int n = j; n < index - 1; n++) {
            personarray[n] = personarray[n + 1];
          }
          index = index - 1;
          break;
        }
        if (j == index - 1) {
          System.out.println("查无此人");
        }
      }
    }
      ;
      break;
    case 3: {
      System.out.println("修改电话本");
      System.out.println("需要修改的姓名：");
      Scanner name00 = new Scanner(System.in);
      String nameedit = name00.next();
      for (int k = 0; k < index; k++) {
        if (nameedit.equals(personarray[k].name) == true) {
          System.out.print("姓名：");
          Scanner xm1 = new Scanner(System.in);
          String name1 = xm1.next();
          System.out.print("性别：");
          Scanner xb1 = new Scanner(System.in);
          String sex1 = xb1.next();
          System.out.print("年龄：");
          Scanner nl1 = new Scanner(System.in);
          String age1 = nl1.next();
          System.out.print("电话：");
          Scanner dh1 = new Scanner(System.in);
          String telnum1 = dh1.next();
          System.out.print("qq：");
          Scanner q1 = new Scanner(System.in);
          String qq1 = q1.next();
          System.out.print("地址：");
          Scanner dz1 = new Scanner(System.in);
          String address1 = dz1.next();
          personarray[k] = new Person(name1, sex1, age1, telnum1,
              qq1, address1);
          break;
        }
        if (k == index - 1) {
          System.out.println("查无此人");
        }
      }
    }
      ;
      break;
    case 4: {
      System.out.println("显示所有电话本");
      for (int l = 0; l < index; l++) {
        System.out.println(personarray[l].toString());
      }
    }
      ;
      break;
    case 5: {
      System.out.println("查询电话本");
      System.out.println("需要查询的姓名：");
      Scanner na = new Scanner(System.in);
      String nameprint = na.next();
      for (int m = 0; m < index; m++) {
        if (nameprint.equals(personarray[m].name) == true) {
          System.out.println(personarray[m].toString());
          break;
        }
        if (m == index - 1) {
          System.out.println("查无此人");
        }
      }
    }
      ;
      break;
    default: {
      System.out.println("无此功能");
    }
      ;
      break;
    }
  }
public Person(String name, String sex, String age, String telnum,
    String qq, String address) {
  this.name = name;
  this.sex = sex;
  this.age = age;
  this.telnum = telnum;
  this.qq = qq;
  this.address = address; 

} 

public String toString() {
  return " [姓名=" + name + ", 性别=" + sex + ", 年龄=" + age + ", 电话="
      + telnum + ",qq=" + qq + ", 地址=" + address + "]";
}
