Did you know about Oriented Object? public class Person { String name; int age; Person(String na) //constructor { this.name = na; } } Person people = new Person("Daniel"); So, new Person() is a object and "people" is a reference, it is the address on memory. String is a object, and variable of String are reference (memory address). Var args is a list of parameter, before you start your program you can set a list... Like the constructor. When calling if to scren, have method called toString(); and it try change addres memory into info. (You can re-write toString(); so it would show something different).

About C, I'm NOT SURE, but sometimes some address have resudie. Think variable are cup, so when you declare a variable are you taking a cup, and put value is like put tea, cofee, water... But if you not take care you can take a dirty cup, so it would have something on... Or it or default value, so it show "2", but I think is because some "dirty address", getting a address already on use.

Java: thank you very much?. Is there a way to access the objects in the class without knowing their names?

https://docs.oracle.com/javase/9/docs/api/java/lang/System.html "System" is class. Inside have "out" that is a reference. Calling "println()" method.

This site https://docs.oracle.com/javase/9/docs/api/java/lang/System.html is experiencing technical difficulty. We are aware of the issue and are working as quick as possible to correct the issue.

For classes, it call toString(), it is a method from all Object. Class Person() { String name; int age; Person(String nam) { this.name = nam } } public Program { public static void main(String[]args) { Person people = new Person("Daniel"); System.out.println(people); //Will put some weird memory address, it is calling toString() System.out.println(people.toString()); // we dont need put toString() because println is calling it already. But we can, same thing. } } But if add public Person { @Override public toString() { Return "My person is " + this.name; } } When: System.out.println(person.toString()); Output: My person is Daniel And if: System.out.println(person); Output: My person is Daniel So, use or not, but the "code memory address" is a method that previous programming did.

Thank you very much 😁. Now I'm going to see if I understand. Because in Java I am the basic level.

No worry, when you get Oriented Object you will understand better, just go on your rythym and lvl.
