Answer 1

Hello!
To begin with, write what exactly you tried and what didn’t work for you.

public class Main {
public static void main(String[] args) {

}
}

The answer to this question is similar to the answer to your previous question. Look at the response of the previous answer. Generate getters and setters.
Next, you get an array of products, and then iterate over it.
