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
<u>Answer:</u>
- <em>A. divide the decimal number by the base value 2</em>
- <em>C. note the remainder separately</em>
- <em>D. divide by 2 until she gets 0 as the remainder</em>
- <em>B. collect the digits in the reverse order</em>
<u>Explanation:</u>
When we want to convert decimal number to a binary number first we have divide the given number by 2. The next step is to note the reminder of the number in the side every division so that the reminder value is the binary value. Repeat this until an zero is encountered.
We have to collate all the remainders from last of first and then the collated number is the answer for the given problem.
<em>So the given option can be ordered as,
</em>
- <em>A</em>
- <em>C</em>
- <em>D</em>
- <em>B</em>
