CORRECT QUESTION:

For the given program, how many print statements will execute?

public static void printShippingCharge(double weight) { if((weight > 0.0) && (weight <= 10.0)){ System.out.println(weight * 0.75); }

else if((weight > 10.0) && (weight <= 15.0)) { System.out.println(weight * 0.85); }

else if((weight > 15.0) && (weight <= 20.0)) { System.out.println(weight * 0.95); } }

public static void main(String args[]) {

printShippingCharge(18);

printShippingCharge(6);

printShippingCharge(25); }

Answer:

Two of the print statements will output values

Explanation:

These two calls to the printShippingCharge are the ones that will output values: printShippingCharge(18); and printShippingCharge(6);

The first if statement is true when the value of weight is 6 (weight > 0.0) && (weight <= 10.0)

The Third if statement  is true when weight is 18 (weight > 15.0) && (weight <= 20.0)

NOTE: That I made correction to the variable weight. The question isn't consistent with the variable name. It used weight and itemWeight at different points this will lead to a compiller error

Cerrena [4.2K]

Answer:

see explaination

Explanation:

import random

def number_guess(num):

n = random.randint(1, 100)

if num < n:

print(num, "is too low. Random number was " + str(n) + ".")

elif num > n:

print(num, "is too high. Random number was " + str(n) + ".")

else:

print(num, "is correct!")

if __name__ == '__main__':

# Use the seed 900 to get the same pseudo random numbers every time

random.seed(900)

# Convert the string tokens into integers

user_input = input()

tokens = user_input.split()

for token in tokens:

num = int(token)

number_guess(num)

Please Help! Unit 6: Lesson 1 - Coding Activity 2
Instructions: Hemachandra numbers (more commonly known as Fibonacci numbers) are found by starting with two numbers then finding the next number by adding the previous two numbers together. The most common starting numbers are 0 and 1 giving the numbers 0, 1, 1, 2, 3, 5...
The main method from this class contains code which is intended to fill an array of length 10 with these Hemachandra numbers, then print the value of the number in the array at the index entered by the user. For example if the user inputs 3 then the program should output 2, while if the user inputs 6 then the program should output 8. Debug this code so it works as intended.

The Code Given:

import java.util.Scanner;

public class U6_L1_Activity_Two{
public static void main(String[] args){
int[h] = new int[10];
0 = h[0];
1 = h[1];
h[2] = h[0] + h[1];
h[3] = h[1] + h[2];
h[4] = h[2] + h[3];
h[5] = h[3] + h[4];
h[6] = h[4] + h[5];
h[7] = h[5] + h[6];
h[8] = h[6] + h[7]
h[9] = h[7] + h[8];
h[10] = h[8] + h[9];
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
if (i >= 0 && i < 10)
System.out.println(h(i));
}
}
