hello.
I try to do so it is 2 people. where you should enter the age, name, address of both people and then print it after you enter what you want when the program runs. and i wondering how do i do return on public p1() and public p2() so i can do it. Or is it a easier way to do it?

Answer 1

This code does not compile. public p1() and public p2() are not valid method declarations. You must at least add a method return type after the public and before the method name, for example:

public Person p1()

Then I guess what you want to do is return a Person object from each of those two methods. Inside the method you must create a new Person object and then return it from the method:

return new Person(name, persnr, adress, age);
