The points a b c and d lie on a straight line ab:bd = 1:4 are A line that extends to infinity on both sides and has no curves is called a straight line.AB:BC=3:4.

<h3>What do you call a straight line?  </h3>

A line is simply an object in geometry denoted as an object with no width that extends on both sides. A straight line is just a line with no curves.

  • AC=AB+BC=3+4=7;  AC:CD=2:1, i.e. AC=2;   because we get 2 different lengths for AC, we change the given ratio AC:CD to an equivalent one with AC=7 .
  • As follows: AC:CD = 2 : 1 = 7 : 3.5 (multiply both sides by 3.5 )   Now we have AC:CD = 7 : 3.5 and AD = AC+CD= 7+3.5 = 10.5,, and the answer is: the ratio  BC:AD = 4:10.5.

In the most common use of the term, a class can be seen as a blueprint used to create objects. In other words, object(s) are created from a class in Java.

<h3>Creating a Class</h3><h3>Code:</h3>

import java.util.*;

class Card{

 private String suit;

 private int value;

 public Card(String s,int v){

   suit = s;

   value = v;

 }

 public String getSuit(){

   return suit;

 }

 public int getValue(){

   return value;

 }

 public void display(){

   System.out.println(value+"("+suit+")");

 }

}

class Deck{

 private ArrayList<Card> deck;

 private ArrayList<Card> drawn;

 public Deck(){

   deck = new ArrayList<Card>();

   drawn = new ArrayList<Card>();

   String[] arr = {"Club","Spade","Heart","Diamond"};

   for(String s : arr){

     for(int i=1;i<=13;i++){

       deck.add(new Card(s,i));

     }

   }

 }

 public void draw(){

   drawn.add(deck.get(0));

   deck.remove(0);

 }

 public void draw(int N){

   if(N > deck.size()){

     N = deck.size();

   }

   for(int i=0;i<N;i++){

     draw();

   }

 }

 public void showDrawn(){

   for(Card c : drawn){

     c.display();

   }

 }

 public void shuffle(){

   Collections.shuffle(deck);

 }

 public void restore(){

   restore(drawn.size());

 }

 public void restore(int N){

   if(N > drawn.size()){

     N = drawn.size();

   }

   for(int i=0;i<N;i++){

     deck.add(drawn.get(0));

     drawn.remove(0);

   }

 }

 public void showDeck(){

   for(Card c : deck){

     c.display();

   }

 }

}

class Test{

 public static void main(String[] args){

   Deck d = new Deck();

   System.out.println("Original deck\n");

   d.showDeck();

   d.draw(8);

   System.out.println("\nDeck after drawing 8 cards\n");

   d.showDeck();

   d.shuffle();

   System.out.println("\nDeck after shuffling\n");

   d.showDeck();

   d.restore();

   System.out.println("\nDeck after restoring cards\n");

   d.showDeck();

 }
