Answer:
The code will give an error that is "At least one public class is required in main file".
Explanation:
In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:
Program:
import java.util.HashSet; //import package
public class A //define class as public.
{
public static void main(String[ ] args) //define main method.
{
HashSet set = new HashSet(); //creating hashset object.
set.add("A"); //add alphabet in hashset
set.add("B"); //add alphabet in hashset
set.add("C"); //add alphabet in hashset
System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.
}
}
Output:
Size of HashSet is : 3
Explanation of the program:
- In the above program, we define a public class that is "A" and inside the class, we define the main method.
- Inside the main method, we create a HashSet class object that is "set".
- To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
The answer to this should be B. Worm. A pinion is a the smallest gear out of the listed ones above. spur would be next then wheel and the biggest if them all would be the spur. I'm not completely sure if my answer is 100% correct, but I feel confident enough about it. Hope this helps. :)
True however it’s also depends on where you live but for this purpose it’s true
Answer:
ValueError
Explanation:
Required
Determine the error the program returned
The above will return a ValueError error and the reason is as follows.
The first line of the program initializes variable as 'live'.
The next line tries to convert answer to integer and this is where it returns the error'.
On the second line, variable amount expects that the answer variable to contain number e.g. '567' but because it doesn't contain a complete number (i.e. unexpected values), the program returns a ValueError.
The most necessary point you need to follow when using a line graph, is to make your graph readable. So, the reason why is it inportant to only graph 1 - 3 series of data is that more than 3 series of data causes too many lines on the graph, which makes ti confusing to read. The last option is the correct one.
