This is the requested code in java.
public class CharTest {
public static String checkCharacter(String text, int index) {
if (0 <= index && index <= text.length()) {
char ch = text.charAt(index);
if (Character.isLetter(ch)) {
return ch + " is a letter";
} else if (Character.isDigit(ch)) {
return ch + " is a digit";
} else if (Character.isWhitespace(ch)) {
return ch + " is a whitespace character";
} else {
return ch + " is an unknown type of character";
}
} else {
return "index " + index.toString() + " is out of range";
} // end if
} // end function checkChar()
public static void main(String[] args) {
// Test the three samples from the specification.
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
} // end function main()
} // end class CharTest
The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.
How it does that is to make use of respective functions defined within the Character class in java. That is
isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.
Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.

Write a python function to compute a certain number to a given power. The program should continue asking the user for number and power and display the result until the user enters 0 as the number. Note: don't use the power function of Python. Compute the power using a for or a while loop.
while True:
number = int(input("input the number: "))
exponent = int(input("input the exponent : "))
if number == 0:
break
else:
result = 1
while exponent != 0:
result *= number
exponent-=1
print("Answer = " + str(result))
we are asked not to use the power function of python. The question wants us to use a for or a while loop to compute the power.
The while loop makes sure the user is always asked to input the number and an exponent.
If the users number equals 0, the while loop will break.
Else the code will find the power of the number.
Finally, we print the answer if the user number is not zero

Each road is associated with a value indicating the level of danger in maintaining that road during winter months. There are many subsets of roads such that the roads in such subsets keep the towns connected directly or indirectly. Each subset is assigned a cost of maintenance, which is directly proportional to the highest danger level of the road present in that subset. The engineer wants to select the smallest subset that keeps the towns connected directly or indirectly and that also has the lowest cost of maintenance. Develop an algorithm to find such a subset. Justify the correctness of your algorithm and derive its runtime.

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.

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
#This calculates the remaining volume
Volume = VBox - VHole
#This returns the volume of the remaining material
return Volume

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.
