Answer 1

public class Student {

    private String no;

    private String name;

    private String age;

    public Student() {
    }

    public Student(String no, String name, String age) {
        this.no = no;
        this.name = name;
        this.age = age;
    }

    public String getNo() {
        return no;
    }

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

    public String getName() {
        return name;
    }

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

    public String getAge() {
        return age;
    }

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

    @Override
    public String toString() {
        return "Student{" +
                "no='" + no + '\'' +
                ", name='" + name + '\'' +
                ", age='" + age + '\'' +
                '}';
    }
}


public class StudentDemo {

    public static void main(String[] args) {
        Student tom = new Student("1", "tom", "20");
        System.out.println(tom);
    }
}
