please help me with this coding problem :)

Consider the following field and incomplete method of some class. The method calcTotal is intended to return the sum of all values in vals.

private int[] vals;

public int calcTotal()
{
int total = 0;

/* missing code */

return total;
}
Which of the code segments shown below can be used to replace /* missing code */ so that calcTotal will work as intended?

I.
for (int i : vals)
{
total += i;
}
II.
for (int pos = vals.length; pos > 0; pos--)
{
total += vals[pos];
}
III.
int pos = 0;
while (pos < vals.length)
{
total += vals[pos];
pos++;
}


I only
II only
I and III
II and III

Consider the following code segment.

int a = 0;
int b = 3;

}
What are the values of a and b after the while loop completes its execution?

a = 4, b = 1
a = 0, b = 3
a = 6, b = 0
a = 8, b = -1

A restaurant recorded the ages of customers on two separate days. You are going to write a program to compare the number of customers in their twenties (ages 20 to 29). What is the missing line of code to count the number of customers in their twenties? customerAges = [13, 3, 11, 24, 35, 25, 15, 18, 1] count20s = 0 if 20 <= item <= 29: count20s = count20s + 1

Consider the following class declarations.

public class Dog
{
private String name;
public Dog()
{
name = "NoName";
}
}
public class Poodle extends Dog
{
private String size;
public Poodle(String s)
{

size = s;
}
}

The following statement appears in a method in another class.
Poodle myDog = new Poodle("toy");
Which of the following best describes the result of executing the statement?

a. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". The instance variable name is not assiged a value.
b. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "NoName".
c. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "toy".
d. A runtime error occurs because super is not used to call the no-argument Dog constructor.
e. A runtime error occurs because there is no one-argument Dog constructor.

The memory hierarchy of a computer system organizes storage by using small, fast, expensive memories at the top of the hierarchy and supplementing them with larger, slower, cheaper memories at each successive level. Explain how the principle of memory locality makes such a system capable of providing efficient access to the data and instructions needed for executing programs.

29. Write a program in a script file that calculates the cost of renting a car according to the following price schedule: The program asks the user to enter the type of car (sedan or SUV), the number of days, and the number of miles driven.

(c) Sedan, 3 days, 511 miles.

SummaryIn this lab, you complete a partially prewritten Java program that uses an array.The program prompts the user to interactively enter eight batting averages, which the program stores in an array. The program should then find the minimum and maximum batting average stored in the array as well as the average of the eight batting averages. The data file provided for this lab includes the input statement and some variable declarations. Comments are included in the file to help you write the remainder of the program.Instructions1.Ensure the file named BattingAverage.java is open.Write the Java statements as indicated by the comments.Execute the program by clicking "Run Code." Enter the following batting averages: .299, .157, .242, .203, .198, .333, .270, .190. The minimum batting average should be .157, and the maximum batting average should be .333.

This program reads a file called 'test.txt'. You are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. Remove punctuations using 'string.punctuation' and 'strip()' before adding words to the wordlist.
Write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. Another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist.
Example:
Contents of 'test.txt':
test file
another line in the test file
Output:
['another', 'file', 'in', 'line', 'test', 'the']
This the skeleton for 1:
#build_wordlist() function goes here
#find_unique() function goes here
def main():
infile = open("test.txt", 'r')
word_list = build_wordlist(infile)
new_wordlist = find_unique(word_list)
new_wordlist.sort()
print(new_wordlist)
main()
