设计一个教师类Teacher,要求： 属性有编号（int no）、姓名（String name）、年龄（int age）、所属学院（String seminary），为这些属性设置相应的get和set方法。 为Teacher类重写equals方法，要求：当两个教师对象的no相同时返回true。 重写Teacher类的toString方法，通过该方法可以返回“no: , name:, age: **, seminary: **”形式的字符串。 输入格式: 两个教师对象的编号，姓名，年龄，学院 输出格式:

以下是实现要求的Java代码：

public class Teacher {
    private int no;
    private String name;
    private int age;
    private String seminary;

    public Teacher(int no, String name, int age, String seminary) {
        this.no = no;
        this.name = name;
        this.age = age;
        this.seminary = seminary;
    }

    public int getNo() {
        return no;
    }

    public void setNo(int no) {
        this.no = no;
    }

    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 getSeminary() {
        return seminary;
    }

    public void setSeminary(String seminary) {
        this.seminary = seminary;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (!(obj instanceof Teacher)) {
            return false;
        }
        Teacher teacher = (Teacher) obj;
        return this.no == teacher.no;
    }

    @Override
    public String toString() {
        return "no: " + no + ", name: " + name + ", age: " + age + ", seminary: " + seminary;
    }
}

你可以使用以下代码进行测试：

Teacher teacher1 = new Teacher(1001, "张三", 35, "计算机科学与技术");
Teacher teacher2 = new Teacher(1002, "李四", 40, "软件工程");
Teacher teacher3 = new Teacher(1001, "王五", 30, "信息管理");

System.out.println(teacher1.equals(teacher2)); // false
System.out.println(teacher1.equals(teacher3)); // true

System.out.println(teacher1); // no: 1001, name: 张三, age: 35, seminary: 计算机科学与技术
System.out.println(teacher2); // no: 1002, name: 李四, age: 40, seminary: 软件工程
System.out.println(teacher3); // no: 1001, name: 王五, age: 30, seminary: 信息管理

输入格式：两个教师对象的编号，姓名，年龄，学院

输出格式：no: **, name: **, age: **, seminary: **
