JAVA语法——构造方法的应用

package 构造方法的应用;

public class Person {
    private String name;
    private String gender;
    private int age;
    
    public Person()
    {
        System.out.println("使用无参构造方法创建对象");
    }
    
    public Person(String name, String gender, int age)
    {
        this.name = name;
        this.gender = gender;
        this.age = age;
        
        System.out.println("使用有参构造方法创建对象");
    }
    
    public String getName()
    {
        return name;
    }
    
    public String getGender()
    {
        return gender;
    }
    
    public int getAge()
    {
        return age;
    }
}

package 构造方法的应用;

public class test {
    public static void main(String[] args)
    {
        Person person1 = new Person();
        Person person2 = new Person("明日科技","男",11);
        
        System.out.println("员工1的信息");
        System.out.println("员工姓名"+person1.getName());
        System.out.println("员工性别"+person1.getGender());
        System.out.println("员工年龄"+person1.getAge());
        
        System.out.println("员工2的信息");
        System.out.println("员工姓名"+person2.getName());
        System.out.println("员工性别"+person2.getGender());
        System.out.println("员工年龄"+person2.getAge());
    }
}
