How to pass Activity values to useful?

Question

I would like to work with the item object but I need to pass values of my activity to the usel someone can explain me?

    item[0] = new ColorClothes();
    item[0].record = 0;
    item[0].color = "blue";
    item[0].clothes = "shoes";

For example where there is "blue" I would like to be receiving a value of my activity as it would be possible?

import java.util.*;


    public class ColorClothes
    {
        public int record;
        public String color;
        public String clothes;

        public static void main(String[] args)
        {
            Initialize();
        }

        public static void Initialize()
        {
            ColorClothes item[] = new ColorClothes[4];

            item[0] = new ColorClothes();
            item[0].record = 0;
            item[0].color = "blue";
            item[0].clothes = "shoes";

            item[1] = new ColorClothes();
            item[1].record = 1;
            item[1].color = "yellow";
            item[1].clothes = "pants";

            item[2] = new ColorClothes();
            item[2].record = 2;
            item[2].color = "red";
            item[2].clothes = "boots";

            item[3] = new ColorClothes();
            item[3].record = 3;
            item[3].color = "black";
            item[3].clothes = "coat";

            System.out.println("Unsorted");

            for(int i = 0; i < item.length; i++)
            {
                System.out.println(item[i].record + "     " + item[i].color + "     " + item[i].clothes);
            }

            System.out.println("\nSorted By Color\n");

            Arrays.sort(item, new ColorComparator());

            for(int i = 0; i < item.length; i++)
            {
                System.out.println(item[i].record + "     " + item[i].color + "     " + item[i].clothes);
            }

            System.out.println("\nSorted By Clothes\n");

            Arrays.sort(item, new ClothesComparator());

            for(int i = 0; i < item.length; i++)
            {
                System.out.println(item[i].record + "     " + item[i].color + "     " + item[i].clothes);
            }

        }

    }

Bom Tiago, I do not see a good reason to try to instantiate a class within itself, I believe that the ideal would be for you to divide this class in two, being one only with the Object that will have the information, and one to do this initialization, arrangement and etc..

This way, each "item" will have a separate data instance.

So I’d do it this way:

Colorclothes:

public class ColorClothes
{

    public ColorClothes() // <------ método construtor
    {
       // O ideal é usar esse método somente para trazer parâmetros iniciais para a instância
    }

    public Clothes[] Initialize(Clothes[] item)
    {
        Clothes item[] = new Clothes[4]; // <----------- utilize o objeto com os dados


        System.out.println("Unsorted");

        for(int i = 0; i < item.length; i++)
        {
            System.out.println(item[i].record + "     " + item[i].color + "     " + item[i].clothes);
        }

        System.out.println("\nSorted By Color\n");

        Arrays.sort(item, new ColorComparator());

        for(int i = 0; i < item.length; i++)
        {
            System.out.println(item[i].record + "     " + item[i].color + "     " + item[i].clothes);
        }

        System.out.println("\nSorted By Clothes\n");

        Arrays.sort(item, new ClothesComparator());

        for(int i = 0; i < item.length; i++)
        {
            System.out.println(item[i].record + "     " + item[i].color + "     " + item[i].clothes);
        }

 return item;

    }


    public class Clothes{
        public int record;
        public String color;
        public String clothes;
   }

    }

In his Activity:

Clothes[] listaClothes = new Clothes[4];
            listaClothes [0] = new Clothes();
            listaClothes [0].record = 0;
            listaClothes [0].color = "blue";
            listaClothes [0].clothes = "shoes";
        listaClothes [1] = new Clothes();
        listaClothes [1].record = 1;
        listaClothes [1].color = "yellow";
        listaClothes [1].clothes = "pants";

        listaClothes [2] = new Clothes();
        listaClothes [2].record = 2;
        listaClothes [2].color = "red";
        listaClothes [2].clothes = "boots";

        listaClothes [3] = new Clothes();
        listaClothes [3].record = 3;
        listaClothes [3].color = "black";
        listaClothes [3].clothes = "coat";



ColorClothes colorClothes = new ColorClothes();    
Clothes[] listaOrganizada= colorClothes.Initialize(listaCloth);

Ready, you will have in your Activity the object that was the "item", containing the 4 objects.
