    Default Help me make a code

    I am a java beginner and started learning java last week.

    I am trying to make a program whereby when i key in the roll number 'for example; person 1' and the program output the name, age, race and sex.

    I did it the long way but it is not what I want,

    public static void main(String[] args) {

    Person person1 = new Person();
    person1.name = "Miyuki";
    person1.race = "Asian";
    person1.sex = "Female";
    person1.age = 35;

    System.out.println(person1.name + " " + person1.race + " " + person1.sex + " " + person1.age);


    That is not what I am aiming for.

    I want the whole thing to come out as one when I key in person 1.
    "name : Miyuki";
    "race : Asian";
    "sex : Female";
    "age : 35;

    NB: I plan also to add person 2. person 3 and so on.

    should I use grid? strring arrays or what?
    Have no idea.

    Help me

    How about something like this ?

    NewClass
    public class NewClass {
     
        public static void main(String[] args) {
            Person person1 = new Person("Miyuki","Asian","Female",35);
            String a = person1.call();
            System.out.println(a);
        }
    }

    Person
    class Person {
        String name,race,sex;
        int age;
     
        Person(String name, String race, String sex, int age) {
            this.name = name;
            this.race = race;
            this.sex = sex;
            this.age = age;         
        }
     
        public String getName() {
            return name;
        }
     
        public void setName(String name) {
            this.name = name;
        }
     
        public String getRace() {
            return race;
        }
     
        public void setRace(String race) {
            this.race = race;
        }
     
        public String getSex() {
            return sex;
        }
     
        public void setSex(String sex) {
            this.sex = sex;
        }
     
        public int getAge() {
            return age;
        }
     
        public void setAge(int age) {
            this.age = age;
        }
     
        public String call(){
            return "name: "+name+"\n"+"race: "+race+"\n"+"sex : "+sex+"\n"+"age : "+age;
        }
    }
    Whatever you are, be a good one
