Question

I have a problem with classes. I made my own class called “Person”. Which takes the parameters “name” and “age”. In my other class i want to make a Person[]. Which works, the main problem is that the array only saves the last entry that I input. How can I fix that?

Please note: This is not homework. I am working on my own project.

code:

     public class Person {

        private static String name;
        private static int age;

        public Person(){
            Person.name = "NAME";
            Person.age = 0;
        }    

        public Diver(String name,int age){
            Person.name = name;
            Person.age = age;

        }

        public static String getName(){
            return Person.name;
        }

        public static int getScore(){
            return Person.age;
        }

        public static String printString(){

            return Person.name + " " + Person.age;
        }


    }

    public class TESTER {
    public static void main(String[]args){
        Person[] persons = new Person[4];
        persons[0] = new Person("bob2",15);
        persons[1] = new Person("bob1",15);
        persons[2] = new Person("bob",16);

        for(int i = 0;i<persons.length;i++){
            System.out.println(persons[i].printString());
        }

    }

}

Answer 1

Don’t make name and age static. Also, make all of your methods non-static.

Static variables are specific to the class. Instance variables are specific to each object of that class.

Then, when inside a class, instead of referring to a variable as Person.name, just refer to it as name
