Answer:

False

Explanation:

namespaces can be nested. That is we can have a hierarchy of namespaces.

For examples suppose we have a namespace top. Within this we have another namespace first. At the next level we have a namespace called second. Then we have a class MyClass as a member of this namespace second. Then the complete description of the class will be as follows:

top::first::second::MyClass

Specific Instructions

Goryan [66]

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();

}
