Answer:
Explanation:
1st mistake: Barcode is written with upeer case, that's not the convention for variables in java, only classes.
2nd: Barcode is public, it is convention to always leave variables private then create getters and setters in case you need to change the value but never acess the variable outside the class it belongs. Also the class should at least have a default constructor in case you are going to instantiate an object outside it.
so the product class should be:
--------------------------------------------------------------------
public class Product {
private int barcode;
public Product() {
// default constructor
}
public int getBarcode() {
return barcode;
}
public void setBarcode(int barcode) {
this.barcode = barcode;
}
}
-------------------------------------------------------------------------
3rd: in the main class now you can instantiate the 2 objects but you are gonna set the variable and get the value through the method, like this:
public class Main {
public static void main(String[] args) {
Product prod1 = new Product();
prod1.setBarcode(123456);
Product prod2 = new Product();
prod2.setBarcode(987654);
System.out.println(prod1.getBarcode());
System.out.println(prod2.getBarcode());
}
}
-----------------------------------------------------------------------------------
Assuming the 2 classes (main and product) are in the same package. But in case they are in different packages, just make sure to import the Product class into the Main class so that you can instantiante an object (new Product()) of it.

Without proper synchronization, which is possible, a deadlock, corrupted data, neither or both? Give reasons for your answer.
need answer pls
Without proper synchronization, corrupted data is possible due to the fact that a shared datum can be accessible by multiple processes.
Data synchronization simply means the idea of keeping multiple copies of dataset in coherence with one another in order to maintain data integrity. It's the process of having the same data in two or more locations.
Without proper synchronization, corrupted data is possible because a shared datum could be accessed by multiple processes without mutual exclusive access.

Write a function named parts that will take in as parameters the dimensions of the box (length, width, and height) and the radius of the hole, and returns the volume of material remaining. Assume the hole has been drilled along the height direction. Note: first write the function assuming the hole has radius less than min(length/2, width/2). For full credit, you will need to account for larger radii (bigger than half the length or width of the box).
The function in Python where comments are used to explain each line is as follows:
#This defines the parts() function
def parts(length, width, height, radius):
#This calculates the volume of the box
VBox = length * width * height
#This calculates the volume of the hole
VHole = 3.142 * radius ** 2 * height

Partially-filled Arrays
Write the function rindby() which stands for remove mark>if not divisiby by. The function removes all elements from the array that are not evenly divisible by the argument n. You can find out if a number is evenly divisible by n using the remainder operator: % (there will be nothing left over).
The function returns the number of items removed or -1 if the array was originally empty.
The function takes 3 arguments:
the array of int that may be modified.
the size of the array (use size_t as the type)
the int n used to check for divisibility
Here are two short examples:
int a[] = {2, 3, 4, 5, 6};
size_t size = 5;
int removed = rindby(a, size, 2);
// removed->2, a = [2, 4, 6], size = 3
size = 0;
removed = rindby(a, size, 3);
// removed-> -1, no change otherwise
In the first case, the numbers 3 and 5 are removed because they are not divisible by 2. Only the numbers that are divisible by 2 are left in the array.
In the second, size has been set to , so the input array is empty and the function returns - 1.
