好的，以下是Java中定义一个Person类，包含姓名、性别、年龄等字段的代码：

public class Person {
    private String name;
    private String gender;
    private int age;
    
    public Person(String name, String gender, int age) {
        this.name = name;
        this.gender = gender;
        this.age = age;
    }
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
    
    public String getGender() {
        return gender;
    }
    
    public void setGender(String gender) {
        this.gender = gender;
    }
    
    public int getAge() {
        return age;
    }
    
    public void setAge(int age) {
        this.age = age;
    }
}

接下来，让我们继承Person类并设计一个Student类，增加学校、班级、学号等字段：

public class Student extends Person {
    private String school;
    private String classNo;
    private String studentNo;
    
    public Student(String name, String gender, int age, String school, String classNo, String studentNo) {
        super(name, gender, age);
        this.school = school;
        this.classNo = classNo;
        this.studentNo = studentNo;
    }
    
    public String getSchool() {
        return school;
    }
    
    public void setSchool(String school) {
        this.school = school;
    }
    
    public String getClassNo() {
        return classNo;
    }
    
    public void setClassNo(String classNo) {
        this.classNo = classNo;
    }
    
    public String getStudentNo() {
        return studentNo;
    }
    
    public void setStudentNo(String studentNo) {
        this.studentNo = studentNo;
    }
}

以上就是在Java中定义一个Person类，以及继承Person类设计一个Student类的代码。
