A Consider the following method definition. The method printAllCharacters is intended to print out every character in str, starting with the character at index 0. public static void printAllCharacters (String str) for (int x = 0; x< str.length(); x++) // Line 3 System.out.print(str.substring(x, x + 1)); The following statement is found in the same class as the printAllCharacters method. printAllCharacters ("ABCDEFG"); Which choice best describes the difference, if any, in the behavior of this statement that will result from changing x < str.length() to x <= str.length() in line 3 of the method?
Α) The method call will print fewer characters than it did before the change because the loop will iterate fewer times.
B) The method call will print more characters than it did before the change because the loop will iterate more times.
C) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.
D) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 8 in a string whose last element is at index 7.
E) The behavior of the code segment will remain unchanged.

Answer:

(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.

Explanation:

Given

printAllCharacters method and printAllCharacters("ABCDEFG");

Required

What happens when  x < str.length() is changed to x <= str.length()

First, we need to understand that str.length()  gets the length of string "ABCDEFG"

There are 7 characters in "ABCDEFG".

So: str.length()  = 7

The first character is at index 0 and the last is at index 6

Next, we need to simplify the loop:

for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)

The above loop will iterate from the character at the 0 index to the character at the 6th index

while

for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)

The above loop will iterate from the character at the 0 index to the character at the 7th index

Because there is no character at the 7th index, the loop will return an error

Hence: (c) is correct

Following are calculations to the given method.

Given:

Method printAllCharacters and printAllCharacters("ABCDEFG") are both required.

To find:

What happens if you change x <str.length() to x = str.length()?

Solution:

The first character is at index 0 while the last is at index 6. The loop should therefore be simplified:

for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)

when

for (int x = 0; x<=str.length(); x++) stands as for (int x = 0; x<= 7; x++).

Therefore, the final answer is "Option (c)"

A user reports slow performance on a computer. A technician checks the computer and finds the RAM utilization Is very high. The technician restarts the computer, and the RAM use is still high. The technician discovers a program running in the background Is using most of the RAM. The user only uses this program once at the end of the year to produce a report. What steps should the technician take to improve the computer's performance?

Write a class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).

Write a public static method named insert. The insert method should have the signature insert(String[] words, String newWord, int place), should return a boolean, and should function as described below.
When called, if place does not represent a valid index for words, then the method will return false to indicate the insertion could not be performed and do nothing else. Otherwise the method will insert the String newWord into the array words at the index place, moving each subsequent entry one place further and losing the final String in the array. The method will then return true to indicate the insertion has taken place.
Use the runner class to test this method: do not add a main method to your code in the U6_L4_Activity_One.java file or it will not be scored correctly.

public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Enter array length:");
int len = scan.nextInt();
scan.nextLine();
String[] wordList = new String[len];
System.out.println("Enter values:");
for(int i = 0; i < len; i++){
wordList[i] = scan.nextLine();
}
System.out.println("Enter new String:");
String insWord = scan.nextLine();
System.out.println("Enter place:");
int pos = scan.nextInt();
System.out.println("Method return: " + U6_L4_Activity_One.insert(wordList, insWord, pos));
System.out.print("Array contents: {");

1.16 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.).
Ex: If the input is:
200000 210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.

private String date; // stores the date as a String
private int time; // in military time, such as 1430 = 2:30 pm
private boolean cloudy; // true if 25% or more of the sky is covered
// constructor not shown, but it initializes all instance variables
// postcondition: returns temperature
public int getTemp()
{

Your task is to implement a function replace_once(t, d), that takes a text t and a replacement dictionary d, and returns the result of replacing words according to the dictionary: if a word appears as a key, replace it with the dictionary value, and if a word does not appear in the dictionary, leave it alone.

Given a list of words, you can concatenate them together with spaces in between as follows:
word_list = "I love eating bananas".split()
print("Word list:", word_list)
back_together = " ".join(word_list)
print("Back together:", back_together)
# You can also join them in other ways, btw. Just DON'T do it for this homework.
print("You can also put commas:", ", ".join(word_list))

Write a program that calculates the shipping charges for parcel. The program should ask the user to enter two floating point values:
The weight of a parcel in pounds
The shipping rate per pound
The program calculates and displays the total shipping charges based on the parcel’s weight and shipping rate per pound.
Your program should print dollars and cents with two decimal places such as 32.85, and not 32.8467777.
Hint: Until we learn how to format output, we will use this little trick. You can round a floating-point value to the nearest hundredth by adding 0.005, multiplying by 100, converting the result to an integer, and then dividing by 100. This trick is not perfect but works well with most values.
Here is a sample of what a typical run of this program looks like where the user entered the values 4.75 for the weight and 2.55 for the shipping rate per pound:
Shipping Charges Calculator
Enter the weight of your parcel in pounds: 4.75
Enter the shipping price per pound: 2.55
The weight of your parcel is 4.75 pounds
The shipping price per pound is $ 2.55
The shipping charges for your parcel is $ 12.11

Write a program that takes a first name and a major as the input and outputs a message with that name and major as shown below Ex. If the input is Nithya and Art the output is Nithya 18 majoring in Art. Use the names and majors of students in your breakout room to test your code. Note that to separate the name from the major as part of the input, you need to place these inputs on separate lines. For the example above, we would provide the input as follows: Nithya Art Hint If you directly add the names and majors inside the print statement, then the code would not work correctly since it is relying on the contents of the provided variables. You need to use these variables inside your print statement, so that regardless of the provided input, the output will always use those values and be as expected Hint. If your code does not pass the tests, make sure you do not have an extra space in your output. Remember.
