java编程题

1. 创建类 Person，其中存储的成员数据为：age(int),sex(boolean),weight(int),至少有一个构造函数可以初始化这三个属性值，同时提供获取这三个属性值的public方法。

Answer 1

public class Person {
    private int age;
    private boolean sex;
    private int weight;
    public Person(int age, boolean sex, int weight) {
        this.age = age;
        this.sex = sex;
        this.weight = weight;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public boolean isSex() {
        return sex;
    }
    public void setSex(boolean sex) {
        this.sex = sex;
    }
    public int getWeight() {
        return weight;
    }
    public void setWeight(int weight) {
        this.weight = weight;
    }
}

public class TestPerson {
    public static void main(String[] args) {
        Person p1 = new Person(21, false, 80);
        System.out.println(p1.getAge());
        System.out.println(p1.isSex());
        System.out.println(p1.getWeight());
        
        p1.setAge(22);
        p1.setSex(true);
        p1.setWeight(60);
        
        System.out.println(p1.getAge());
        System.out.println(p1.isSex());
        System.out.println(p1.getWeight());
    }
}
