Anti Pattern – Javabean Pattern

Call a non-argument constructor, then call a series of set method. Avoid using it.

class Person {
    String firstName;
    String lastName;
    int age;
    
    public Person() {}

    public String getFirstName() {
        return this.firstName;
    }
    
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    
    public String getLastName() {
        return this.lastName;
    }
    
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    
    public int getAge() {
        return this.age;
    }
    
    public void setAge(int age) {
        this.age = age;
    }

}
