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.
Answer:
Scaling changes the size of the whole image by resampling it(duplicating the pixels). in cropping you only get a part of the original image/ remove the outer area of it .

Answer:
There is no value of the number variable, for which the loop can be true in any iteration.
Explanation:
- The above loop states the condition that the value should be less than 100 and greater than 500. It is because the loop holds the and condition which gives the true if both conditions will be true.
- The first condition of the while loop states that the value of the number variable is less than the 100.
- The second condition of the while loop state that the value of the number variable is greater than the 500.
- The and condition of the while loop will true if both conditions will true.
- But there is no number which is less than 100 and greater than 500.
- So no number can satisfy the while condition to be true.
The answer is D. Crankshaft. The flywheel is connected to the crankshaft. The crankshaft<span> is </span>connected<span> to the pistons and moves in a circular motion to move the engine. Spark Plugs are based at the top of the pistons, this is used to ignite fuel in the pistons that move them. The timing belt is </span>connected to the crankshaft<span> and it rotates the camshaft. </span>
Answer:
The output of this code can be given as follows:
Output:
Here There Everywhere
But notin Texas
Explanation:
In the give java code a class "Questions" is defined inside this class the main method is defined in the main method we use three print function that can be described as follows:
- In the first print function, we print the message that is "Here".
- In the second and third print function, we use println that print data or message in the next line that is "There Everywhere"
and in the next line "But not" and "in Texas".
