singleton is a object that can be created only x amount of times, usually once.
used for objects like server connection and rare game objects.

singleton class :

Code:: package singleton;

public class Singleton {
private static Singleton singleton; // array this to get x number of singletons enabled
private Singleton() {
   System.out.println("new singleton instace has been created");
}
public static Singleton newInstance() {
   if(singleton == null) {
      singleton = new Singleton();
   }
   return singleton;
}
}

summoning the singleton object :

Code:: package singleton;

public class Main {

public static void main(String[] args) {
   // TODO Auto-generated method stub
   Singleton sing1 = Singleton.newInstance(); // can only create 1, all others point to the same object


}

}

Code:: package singleton;

public class Deck {
private static Deck singleton;

}
public static Deck newInstance() {
   if(singleton == null) {
      singleton = new Deck();
   }
   return singleton;

cards[i].color = "red";
cards[i].level = i-38;
}
}
public void printDeck() {
for (int i = 0; i < 52; i++) {
cards[i].printCard();
}

}
}

summoning a singleton Deck object (itch turn ichido(one time)) :

Code:: package singleton;

public class Main {

public static void main(String[] args) {
   // TODO Auto-generated method stub
   Deck sing1 = Deck.newInstance(); // can only create 1, all others point to the same object


}

an abs class doesn't have to have a constructor.

Code:: public abstract class AbsShape {
public abstract int Area();
}

2nd class :

Code:: import java.util.regex.Matcher;

public class Square extends AbsShape{
private int side;

public int getSide() {
   return side;
}

public void setSide(int side) {
   this.side = side;
}

public Square(int side) {
   super();
   this.side = side;
}

@Override
public int Area() {
   // TODO Auto-generated method stub
   return (int)Math.pow(side, 2); // powe ^
}

}

Code:: public class Main {

public static void main(String[] args) {
   // TODO Auto-generated method stub
   AbsShape ribua = new Square(5);
   System.out.println("area: " + ribua.Area());
}

}

an abstract class doesn't have to have a constructor.

Code:: public abstract class BaseClass {
protected int x = 100; // visible to this base class and sub classes(that extend it)
protected int y = 150;

public int getX() {
   return x;
}

public void setX(int x) {
   this.x = x;
}

public int getY() {
   return y;
}

public void setY(int y) {
   this.y = y;
}

public abstract void AbstractMethode();

}

derived class :

Code:: public class DerivedClass extends BaseClass{

@Override
public void AbstractMethode() {this.x++;this.y++;}
}

main :

Code:: public class Main {

public static void main(String[] args) {
   BaseClass patamon = new DerivedClass();
   patamon.AbstractMethode();
   System.out.println(patamon.getX() + " " + patamon.getY());
}

}

output : 101 151

an interface is like an item an object class can be equiped with.
interface contains methode signatures that has to be implemented in your object class.

right click the project folder in the package explorer window, interface.

Code:: public interface MyCalc {
public int Add(int x, int y);
public int subtract(int x, int y);
public int Multiple(int x, int y);
public int div(int x, int y);
}

2nd interface :

Code:: public interface MyCalc2 {
public int Multiple(int x, int y);
public int sum(int ... sigma);
}

create a class and add implements MyCalc,MyCalc2.
next click the error line under the class name and click add unimplemented methods.
finnally fill in the methodes body.
to get :

Code:: public class MainClass implements MyCalc,MyCalc2 {

@Override
public int sum(int... sigma) {
   // TODO Auto-generated method stub
   int result = 0;
   for (int i = 0; i < sigma.length; i++) {
      result += sigma[i];
   }
   return result;
}

@Override
public int Add(int x, int y) {
   // TODO Auto-generated method stub
   return x+y;
}

@Override
public int subtract(int x, int y) {
   // TODO Auto-generated method stub
   return x-y;
}

@Override
public int Multiple(int x, int y) {
   // TODO Auto-generated method stub
   return x*y;
}

@Override
public int div(int x, int y) {
   // TODO Auto-generated method stub
   return x/y;
}

}

and creat some main class to test MainClass

(concept) summoning requests from cmds :
token class (the above pattern) :

Code:: import java.util.HashSet;
import java.util.Scanner;

public class TokenClass {
private static HashSet<String> CMDs = new HashSet<>();
// AGI, goals
public static void enable(String cmd, String skill) {CMDs.add(cmd+" " + skill);}
public static void disable(String cmd, String skill) {CMDs.remove(cmd+" " + skill);}
public static boolean isAble(String cmd, String skill) {return CMDs.contains(cmd+" " + skill);}
// public static void enableWithGoalBundle(String bundle, String cmd, String skill) {
//    CMDs.add(bundle + " " + cmd + " " + skill);
//    }
public void Activate(String cmd, String g) {
   if(isAble(cmd, g)) {
      switch (g) {
      case "create":
         Scanner s1 = new Scanner(System.in);System.out.println("enter name");
         String x = s1.next();
         System.out.println("enter field_value_field_value...");
         String y = s1.next();
         y= y.replaceAll("_", " ");
         JsonCRUDA.create(x, y);
         break;

      default:
         break;
      }
   }
   else {System.out.println("unAble to do that");}
}
}

JSON Create Remove Update Delete Add

Code:: import org.json.JSONArray;
import org.json.JSONObject;

public class JsonCRUDA{
private static JSONObject cars = new JSONObject();
public static JSONObject getCars() {
   return cars;
}

public static boolean create(String name, String attributes) {

   for (int i = 0; i < strArr.length / 2; i++) {
      cars.getJSONArray(name).getJSONObject(0).put(strArr[i*2], strArr[i*2+1]);
   }
   System.out.println(cars);

   return false;
}

public static String Read(String name, String Id, String field) {
   // TODO Auto-generated method stub
   String result="";
   JSONArray jArr = cars.getJSONArray(name);
for (Object object : jArr) {
if(((JSONObject)object).get("id").equals(Id))
{result = ((JSONObject)object).get(field).toString();break;}
}
   return result;
}

public static boolean Update(String name, String Id, String field, String newVal) {
   // TODO Auto-generated method stub
   JSONArray jArr = cars.getJSONArray(name);
for (Object object : jArr) {
if(((JSONObject)object).get("id").equals(Id))
{((JSONObject)object).put(field, newVal);break;}

}
System.out.println(cars);
   return false;
}

public static boolean delete(String name) {
   // TODO Auto-generated method stub
   cars.remove(name);
   System.out.println(cars);
   return false;
}

public static boolean Add(String name, String attributes) {
   // TODO Auto-generated method stub
   String[] strArr = attributes.split(" ");
   cars.put(name, new JSONArray());
   cars.getJSONArray(name).put(new JSONObject());
   for (int i = 0; i < strArr.length / 2; i++) {
      cars.getJSONArray(name).put(new JSONObject().put(strArr[i*2], strArr[i*2+1]));
   }
   System.out.println(cars);
   return false;
}

}

Json Print class :

Code:: import org.json.JSONArray;
import org.json.JSONObject;

public class printJson {
public static void print(JSONObject x) {System.out.println(x);}
public static void printCarJsonSum(JSONObject x) {
   double sum=0;
   for(String s : x.keySet()) {
   JSONArray jArr = x.getJSONArray(s);
   for (Object object : jArr) {
   sum += ((JSONObject)object).getDouble("price")*((JSONObject)object).getDouble("quantity");
   }
   }
   System.out.println(sum);
}
}

Main :

Code:: import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

import org.json.JSONArray;
import org.json.JSONObject;

public class main {

public static void main(String[] args) {
   TokenClass tokenClass = new TokenClass();
   tokenClass.enable("secratary", "create");//init
   tokenClass.Activate("secratary", "create");

   //String path = "C:\\Users\\Lenovo\\eclipse-workspace\\Json\\writeDepottest2.json"; //"C:\\Users\\Lenovo\\Desktop\\HW\\writeDepottest.json";
//JsonCRUDA carSys = new JsonCRUDA();
   JsonCRUDA.create("delorean", "price 30000 id flaxCapacitor quantity 1");
   JsonCRUDA.Add("nightRider", "price 1000 id wheel quantity 4");
   JsonCRUDA.delete("nightRider");
   JsonCRUDA.create("nightRider", "price 1000 id wheel quantity 4");
System.out.println(JsonCRUDA.Read("delorean", "flaxCapacitor", "price"));
JsonCRUDA.Update("delorean", "flaxCapacitor", "price", "60000");
printJson.print(JsonCRUDA.getCars());
printJson.printCarJsonSum(JsonCRUDA.getCars());
// FileWriter fWriter;
// try {
// fWriter = new FileWriter(path);
// fWriter.write(cars.toString());
// fWriter.close();
//
// }
// catch (IOException e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
}
}

the project isn't clean or complete (cost time) but the concept is there (HADOUKEN )
