Answer:

Scanner in = new Scanner(System.in);

System.out.print("Please enter 3 sides of a triangle, color and " +

"whether it is filled or not (true false): ");

double s1 = in.nextDouble();

double s2 = in.nextDouble();

double s3 = in.nextDouble();

String color = in.next();

boolean filled = in.nextBoolean();

Triangle t1 = null;

try {

t1 = new Triangle(s1, s2, s3, color, filled);

}

catch (IllegalTriangleException ite) {

System.out.println(ite.toString());

}

System.out.println(t1.toString());

System.out.printf("Triangle color: %s, Triangle filled: %s%n" +

The stub: transmits the message to the server where the server side stub receives the message and invokes procedure on the serve

elena55 [62]

Answer:

It does all of these

Explanation:

The stub is able to do all of what we have in this question. It can locate computer connections, locate ports on a computer, transit message to server etc.

in distributed computing, a stub is a piece of code that does the work of converting parameters that are passed between the client and the server at a time of remote procedure call.

The main objective of an RPC is to allow the client to call procedures remotely on another server.

Write the function definition for a function called list_total that accepts a list of integers

uranmaximum [27]

Answer:

def list_total(numbers):

sum_of_numbers = 0

for number in numbers:

sum_of_numbers += number

return sum_of_numbers

Explanation:

So, to define a function, the syntax is simply:

def functionName(arguments here):

# code

So to define a function called "list_total" which accepts a list of integers, you write:

"

def list_total(numbers):
# code

"

any the "numbers" is a parameter, and it's just like any variable, so you can name it anything besides keywords. I just named it "numbers" since it makes sense in this context, you could also write "integers" instead and it would be just as valid, and may be a bit more specific in this case.

Anyways from here, the initial sum should be equal to 0, and from there we add each number in the list to that initial sum. This can be done by initializing a variable to the value "0" and then traversing the list using a for loop. This can be done as such:

"

def list_total(numbers):

sum_of_numbers = 0

for number in numbers:

# code

"

So for each element or integer in the list "numbers" the for lop will run, and the variable "number" will contain the value of the current element it's on.

So we can add the "number" to the sum_of_numbers as such:

sum_of_numbers = sum_of_numbers + number

but there is a shorter way to do this, and it's represented as:

sum_of_numbers += sum_of_numbers

which will do the same exact thing. In fact this works for any mathematical operation for example:

a *= 3

is the same thing as

a = a * 3

and

a /= 3

is the same thing as

a = a / 3

It's the same thing, but it's a much shorter and more readable notation.

Anyways, this code will go in the for loop to almost finish the code

"

def list_total(numbers):

sum_of_numbers = 0

for number in numbers:

sum_of_numbers += number

"

The last thing is to return this value, and this is simply done by using the syntax:

"return {value here}"

and since the sum_of_numbers has the value, we write

"return sum_of_numbers"

at the end of the function, which is very very important, because when you use the return keyword, you end the function, and return whatever value is next to the return to the function call

So to finish the code we just add this last piece to get:

"

def list_total(numbers):

sum_of_numbers = 0

for number in numbers:

sum_of_numbers += number

return sum_of_numbers

"
