Answer:

The answer is "Option A"

Explanation:

In the given java code, a class "Test" is defined, inside the main method try and catch block is used, inside the try block method "p()" is called, that print a message. in this block two catch block is used, that works on "NumberFormatException" and "RuntimeException". In the method "p" declaration, a string variable "s" is defined, that holds double value, that is "5.6", and converts its value into the wrong integer, and other wrong option can be described as follows:

In option B, it is wrong, it is not followed by after call method.
In option C, It is not followed by runtime exception, that's why it is incorrect.
Option D and Option E both were wrong because they can't give run time and compile-time error.

Question 1. (50 points) 1.Write a program that computes information related to a sequence of entries regarding age of customers.

schepotkina [342]

Answer:

The solution code is written in Python 3:

count = 0
totalAge = 0
group1_count = 0 #age < 10
group2_count = 0 #age 10 - 20
group3_count = 0 #age 20 - 40
group4_count = 0 #age > 40
group1_total = 0 #subtotal age <= 10
group2_total = 0 #subtotal age 11 - 20
group3_total = 0 #subtotal age 21 - 40
group4_total = 0 #subtotal age > 40
age = int(input("Input an age: "))
youngest = age
oldest = age
while(age != -1):
count += 1
totalAge += age
if(age <= 10):
group1_count += 1
group1_total += age
elif(age <= 20):
group2_count += 1
group2_total += age
elif(age <= 40):
group3_count += 1
group3_total += age
else:
group4_count += 1
group4_total += age
if(youngest > age):
youngest = age
if(oldest < age):
oldest = age
age = int(input("Input an age: "))
totalCustomer = count
avgAge = totalAge / count
rangeAge = oldest - youngest
avgAgeGroup1 = group1_total / group1_count
avgAgeGroup2 = group2_total / group2_count
avgAgeGroup3 = group3_total / group3_count
avgAgeGroup4 = group4_total / group4_count
print("The total number of customers: " + str(totalCustomer))
print("Total number of customer in Group 1 (<=10): " + str(group1_count))
print("Total number of customer in Group 2 (11 - 20): " + str(group2_count))
print("Total number of customer in Group 3 (21 - 40): " + str(group3_count))
print("Total number of customer in Group 4 (> 40): " + str(group4_count))
print("Average age for all customer: " + str(avgAge))
print("Youngest age: " + str(youngest))
print("Oldest age: " + str(oldest))
print("The range of age: " + str(rangeAge))
print("Average age for group 1 (<=10): " + str(avgAgeGroup1))
print("Average age for group 2 (11 - 20): " + str(avgAgeGroup2))
print("Average age for group 3 (21 - 40): " + str(avgAgeGroup3))
print("Average age for group 4 (> 40): " + str(avgAgeGroup4))

Explanation:

Firstly, create the counter variables (e.g. count, group1_count, group2_count etc ) to track the total number of customer and number in each age group. Besides, create variables to hold the value of total of age and sub-total of each age group (Line 1 - 10). We presume there are only four age groups.

Next, prompt user to input the first age (Line 12)

Create variable youngest and oldest to track the lowest and highest age (Line 13 -14). At the moment, set the first input age as value of youngest and oldest.

Create a while loop with sentinel value -1 (Line 16). Within the loop, track the customer occurrence by incrementing counter variables by one (Line 17, 21, 24, 27 & 30). At the same time, add the current input age to totalAge and to group total (Line 18, 22, 25, 28, & 31).

If the current youngest value is bigger than the current input age, we set the current age to youngest (Line 33- 34).

If the current oldest value is smaller than the current input age, we set the current age to oldest (Line 36- 37).

After terminating the loop with -1, calculate the average age for all customers and for each age group and the range of age (Line 42- 48)

At last, display all the required calculation results using print function (50 - 62)

Write a program whose inputs are three integers, and whose outputs are the largest of the three values and the smallest of the t

arlik [135]

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter the first number: ");

int n1 = input.nextInt();

System.out.print("Enter the second number: ");

int n2 = input.nextInt();

System.out.print("Enter the third number: ");

int n3 = input.nextInt();

System.out.println("largest: " + LargestNumber(n1, n2, n3));

System.out.println("smallest: " + SmallestNumber(n1, n2, n3));

}

public static int LargestNumber(int num1, int num2, int num3){

int largestNum = 0;

if(num1>=num2 && num1>=num3)

largestNum = num1;

else if(num2>=num1 && num2>=num3)

largestNum = num2;

else if(num3>=num1 && num3>=num2)

largestNum = num3;

return largestNum;

}

public static int SmallestNumber(int num1, int num2, int num3){

int smallestNum = 0;

if(num1<=num2 && num1<=num3)

smallestNum = num1;

else if(num2<=num1 && num2<=num3)

smallestNum = num2;

else if(num3<=num1 && num3<=num2)

smallestNum = num3;

return smallestNum;

}

Explanation:

Create function called LargestNumber that takes three parameters, num1, num2, num3. Find the largest number using if else structure among them and return it. For example, if num1 is both greater than or equal to num2 and num3, then it is the largest one.

Create function called SmallestNumber that takes three parameters, num1, num2, num3. Find the smallest number using if else structure among them and return it. For example, if num1 is both smaller than or equal to num2 and num3, then it is the smallest one.

Inside the main, ask the user for the inputs. Call the functions and print the largest and smallest.
