1 编写一个学生类，提供name, age, gender, phone, address, email成员变量，并实现以下的功能。 1.1为每个成员变量提供getter和setter方法 1.2为学生类提供默认构造器和带所有成员变量的构造器 1.3为学生类提供描绘吃、喝、玩、睡等行为的方法 1.4在主方法中定义一个学生类的数组，用来保存通讯录数据，寻找本班5-10位同学的相关信息保存进该数组中 定义方法，可以通过name, email或者address来查询学生信息，如果找不到数据，则进行友好的提示

以下是学生类的代码实现：

public class Student {
    private String name;
    private int age;
    private String gender;
    private String phone;
    private String address;
    private String email;

    public Student() {
    }

    public Student(String name, int age, String gender, String phone, String address, String email) {
        this.name = name;
        this.age = age;
        this.gender = gender;
        this.phone = phone;
        this.address = address;
        this.email = email;
    }

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public void eat() {
        System.out.println("我在吃饭");
    }

    public void drink() {
        System.out.println("我在喝水");
    }

    public void play() {
        System.out.println("我在玩游戏");
    }

    public void sleep() {
        System.out.println("我在睡觉");
    }
}

以下是在主方法中使用学生类的数组保存通讯录数据，并实现通过name、email或者address来查询学生信息的代码实现：

public class Main {
    public static void main(String[] args) {
        Student[] students = new Student[10];
        students[0] = new Student("张三", 18, "男", "123456789", "北京市海淀区", "zhangsan@qq.com");
        students[1] = new Student("李四", 19, "女", "987654321", "上海市浦东新区", "lisi@qq.com");
        students[2] = new Student("王五", 20, "男", "12348765", "广州市天河区", "wangwu@qq.com");
        students[3] = new Student("赵六", 21, "女", "87654321", "深圳市南山区", "zhaoliu@qq.com");
        students[4] = new Student("钱七", 22, "男", "123456789", "杭州市西湖区", "qianqi@qq.com");
        students[5] = new Student("孙八", 23, "女", "987654321", "成都市锦江区", "sunba@qq.com");
        students[6] = new Student("周九", 24, "男", "12348765", "南京市鼓楼区", "zhoujiu@qq.com");
        students[7] = new Student("吴十", 25, "女", "87654321", "武汉市洪山区", "wushi@qq.com");
        students[8] = new Student("郑十一", 26, "男", "123456789", "重庆市江北区", "zhengshiyi@qq.com");
        students[9] = new Student("王十二", 27, "女", "987654321", "苏州市工业园区", "wangshier@qq.com");

        Student foundStudent = findStudentByName(students, "张三");
        if (foundStudent != null) {
            System.out.println("找到了学生：" + foundStudent.getName() + "，年龄：" + foundStudent.getAge() + "，性别：" + foundStudent.getGender());
        } else {
            System.out.println("未找到该学生");
        }

        foundStudent = findStudentByEmail(students, "zhaoliu@qq.com");
        if (foundStudent != null) {
            System.out.println("找到了学生：" + foundStudent.getName() + "，年龄：" + foundStudent.getAge() + "，性别：" + foundStudent.getGender());
        } else {
            System.out.println("未找到该学生");
        }

        foundStudent = findStudentByAddress(students, "广州市天河区");
        if (foundStudent != null) {
            System.out.println("找到了学生：" + foundStudent.getName() + "，年龄：" + foundStudent.getAge() + "，性别：" + foundStudent.getGender());
        } else {
            System.out.println("未找到该学生");
        }

        foundStudent = findStudentByName(students, "陈十三");
        if (foundStudent != null) {
            System.out.println("找到了学生：" + foundStudent.getName() + "，年龄：" + foundStudent.getAge() + "，性别：" + foundStudent.getGender());
        } else {
            System.out.println("未找到该学生");
        }
    }

    public static Student findStudentByName(Student[] students, String name) {
        for (Student student : students) {
            if (student.getName().equals(name)) {
                return student;
            }
        }
        return null;
    }

    public static Student findStudentByEmail(Student[] students, String email) {
        for (Student student : students) {
            if (student.getEmail().equals(email)) {
                return student;
            }
        }
        return null;
    }

    public static Student findStudentByAddress(Student[] students, String address) {
        for (Student student : students) {
            if (student.getAddress().equals(address)) {
                return student;
            }
        }
        return null;
    }
