Can someone tell me why this code in Java won't run?

if (s.toLowerCase().equals(s.toUpperCase()))
{
System.out.println("*");
}

Answer:

Here is the Python program:

import random #to generate random numbers

def generateRandNo(): #function to generate random number

    randNo = random.randint(1,100) #generates random number in range from 1 to 100

    return randNo #returns the generated random number

def userInput(message = "Guess the number "): #to gets integer input from user and return the input number

    userGuess = int(input(message)) #store the int type input from user in userGuess variable

    return userGuess #returns the user input number

def compareNumbers(userGuess,randNo): #compares the user input with actual randomly generated number

    if userGuess > randNo: # if user input is greater than actual number

         return "The number is too high"

    elif userGuess < randNo: #if user input is less than actual number

         return "The number is too low"

    else: #if user guess is correct

         return "Correct"

def main(): #main method

    correct = False #sets correct to False

    begin = True #sets start game i.e. begin to True

    while correct or begin: #while loop keeps repeating as long as user guess is correct or user wants to start game again

         guessCount = 0  #counts number of trials user takes to guess the correct number

         randNo = generateRandNo() #generates a random number using generateRandNo

         userGuess = userInput() #gets input number from user using userInput method

         guessCount+=1 #increments at each guess made by user

         message = compareNumbers(userGuess,randNo) #compares user guess input number with actual number

         while message != "Correct" : # while message is not equal to Correct

              print(message) #prints to guess the number

              userGuess = userInput("Try again: ") #keeps asking user to try again and enter a number

              guessCount = guessCount + 1 #increments guessCount  by 1 at each guess made by user

              message = compareNumbers(userGuess,randNo) #compares user input with actual number

         print()

         print(message,"It took you ",guessCount," attempts to answer\n") #prints how much trials user took to guess correct number

         choice = input("Do you wish to continue? (Enter yes or no) ") #asks user if user wants to start over

         if choice == 'no': # if user enters no

              exit(1) #exits the program

         else: #if user enters yes starts the game again

              correct = True #sets correct guess to True

main() #calls main method to start the guess game

Explanation:

The program is well explained in the comments attached with each line of the code. Suppose the randomly generated number (actual number) is 50 and user input is 24  then message The number is too low is displayed and if user guess input is 80 then The number is too high is displayed. If the user guesses the correct number i.e. 50 3rd time then the message displayed is:

It took you 3 attempts to answer.

The the user is asked to continue as:

Do you wish to continue? (Enter yes or no)

If user enters no the program exits if yes then user is asked to Guess the number again.

An instance of such program written in python is

isum = 0

for i in range(1,11):

isum = isum + i

print(sum)

One of the ways the program can give a wrong result is when someone alters the program source program before it's complied and executed.

Take for instance.

Changing

isum = 0 to isum = 4

will alter the result by additional 4

Another way is if an outside program or process alters the program execution.

In point a:

It utilizes multiple algorithms based on machine learning can understand the attributes or transform their probability into projections. Its algorithms could be used, including such neural computer systems or artificial neural networks. Whenever the input, as well as the target outcome, are taken their possibilities are converted in forecasts, so that if the input, as well as the corresponding results, are balanced.

In point b:

The operating curves of its receiver is indeed a plot of its true positives for its incorrect positive rate. It could be used in different tests for treatment. It indicates the variations of its responsiveness between all the two components and also the accuracy. Line slopes supply LR with a value.

Explanation:

1.

the answer to the first question is organizational unit. this is because in this scenario that we have before us, cost is a deciding factor. a unit as this can adapt to changes, it is flexible and also not very complex

2.

answer to question 2 is PDC emulator. this emulator can perform the function synchronization of time across every domain controller that is in the domain. other of its functions are, authentication and changing of passwords.

3.

the answer to the 3rd question is child domain. It is a factor in this scenario because it works well in a situation where there is an issue of slow network connection.

The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.

The short quiz program is as follows.

Please note that comments are used to explain difficult lines.

import java.util.*;

public class shortQuiz{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

//This declares the variables that represent correct answers as boolean data type; the variables are also initialized

 boolean q1 = true, q2 = false, q3 = true;

//This declares the response to each question as boolean data type

 boolean q1response, q2response, q3response;

//This prints the first question

 System.out.print("Java is a programming language, true or false? ");

//This gets input for the first response

 q1response = input.nextBoolean();

//This prints the second question

 System.out.print("Only numbers can be stored by variables in Java, true or false? ");

//This gets input for the second response

 q2response = input.nextBoolean();

//This prints the third question

 System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");

//This gets input for the third response

 q3response = input.nextBoolean();

//This prints your first response, alongside the correct answer to the first question

 System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);

//This prints your second response, alongside the correct answer to the second question

 System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);

//This prints your third response, alongside the correct answer to the third question

 System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);

//The program ends here

}

}

See attached image for program sample run.

The above program initializes the correct answers using boolean variables. The correct answers are then printed, after the user answers the three questions.

Follows are the code to this question:

public class FormLetterWriter//defining class

{

static void displaySalutation(String last_Name)//defining a method displaySalutation  

   {

       System.out.println("Dear Mr. or Ms. " + last_Name);//print value

   }

   static void displaySalutation(String first_Name, String last_Name) //overload the method displaySalutation

   {

       System.out.println("Dear " + first_Name + " " + last_Name);//print value

   }

   public static void message()//defining a method message  

   {

       System.out.println("Thank you for your recent order.");//print message

   }

       displaySalutation("I Kell");//calling a method displaySalutation by passing a single String value

       message();//calling message method

       displaySalutation("Christ", "John");//calling a method displaySalutation by passing a two String value

       message();//calling message method

   }

}

Output:

please find the attached file.

Explanation:

In the above given program a calss "FormLetterWriter" is defined, in side the class we perform the method overloading, in which a method "displaySalutation" is used in first definition it accepts a single string variable "first_Name", and in second time, it accept two string variable " first_Name and last_Name".

Inside the both method, we use print method, that print its value, and an onther method message is defined, that print the given message.

In the class main method is declared, in which we apply mathod overloading and also call the message method for print the given business letter.
