Create a Flash Card class. Flash Cards have a Question and an Answer, each of which are Strings. Your class should include a con

xeze [42]

Answer:

<u> FlashCard.java</u>

public class FlashCard {
String Question;
String Answer;
public FlashCard(String q, String a){
this.Question = q;
this.Answer = a;
}
public String toString(){
String output = "";
output += "Question: " + this.Question + "\n";
output += "Answer: " + this.Answer;
return output;
}
public boolean equals(String response){
if(this.Answer.equals(response)){
return true;
}
else{
return false;
}
}
}

public class Main {
public static void main(String[] args) {
FlashCard card1 = new FlashCard("What is highest mountain?", "Everest");
FlashCard card2 = new FlashCard("What is natural satelite of earth?", "Moon");
FlashCard card3 = new FlashCard("Who is the first president of US?", "George Washington");
FlashCard cards [] = {card1, card2, card3};
for(int i=0; i < cards.length; i++){
System.out.println(cards[i]);
}
}
}

Explanation:

In FlashCard.java, we create a FlashCard class with two instance variable, Question and Answer (Line 2 - 3). There is a constructor that takes two input strings to initialize the Question and Answer instance variables (Line 5-8). There is also a toString method that will return the predefined output string of question answer (Line 10 - 15). And also another equals method that will take an input string and check against with the Answer using string equals method. If matched, return True (Line 17 -24).

In Main.java, create three FlashCard object (Line 3-5) and then put them into an array (Line 6). Use a for loop to print the object (Line 8-10). The sample output is as follows:

Question: What is highest mountain?

Answer: Everest

Question: What is natural satelite of earth?

Answer: Moon

Question: Who is the first president of US?

Answer: George Washington
