Answer 4

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).

Answer 5

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.

Answer 6

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

Answer 7

Sorry, I didn't understand, can you give me a example?

Answer 8

ok.

Thank you very much. I want to know how the function System.out.println (); Pull the text across the screen.

Answer 10

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.

Answer 12

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.

Answer 13

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

Answer 14

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