TRUE OR FALSE. Write TRUE if the statement is true, otherwise, writeFALSE.If P and Q are true statements and R is a false statement, then the statement (P ∧ Q) ∨ R ⇒ (¬Q) is true.

2. The formal parameters occur in the procedure call, while the real parameters appear in the method header.
For this discussion, we are going to be working with operators. Below is the code for the Operators class, which contains a main() method and a divisible() method.
Study the code below, paying special attention to the four if statements. First, explain using complete sentences how each if statement evaluates (true or false), as well as what takes place in each if statement's test (comparisons, function calls, increments/decrements, etc.). Then, provide what the program will output.
public class Operators {
public static void main(String[] args) {
int a = 5, b = 10, c = 11;
System.out.println("This program works with operators.");
if (a < 10 ^ b == 10)
System.out.println("Java ");
if (divisible(b, a) | divisible(c, a))
System.out.println("Programming ");
if (a + b - (++c) == c - (b--) + 1)
System.out.println("CITC ");…

- Write a program that uses the class productType defined in Exercises 8 and 10 of this chapter.arrow_forwardProgram 1: Write a program that asks the user to input a sentence and then outputs the sentence back with the case of every character reversed. So for example: “CaTs RuLe!” would be given back as “cAtS rUlE!” . Spaces and punctuation should be left in place. You can use the Character class static functions to test the case of each letter. You do not need to place any code in static methods (besides the main method), you do not need to worry about try/catch blocks, and you do not need to make the program run more than once. in javaarrow_forwardQ1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams. Sample Input #1: Enter two strings: teach peach Sample Output #1: The string “teach” and “peach” aren’t anagrams.arrow_forward
- A student makes the following argument. if I receive a good grade, the instructor teaches well. I didn't receive a good grade. Therefore, the instructor didn't teach well. is the student's argument valid? Let A be the statement, "I receive a good grade" and B be the statement, " the instructor teaches well." Then, rewrite the above paragraph using A and B.arrow_forwardPlease help with 3rd section (in images below), code for first and second class included below. Do not change the function names or given starter code in the script. Each class has different requirements, read them carefully. Do not use the exec or eval functions, nor are you allowed to use regular expressions (re module). All methods that output a string must return the string, not print it. If you are unable to complete a method, use the pass statement to avoid syntax errors. class Stack: def __init__(self): self.stack = [] def pop(self): if len(self.stack) < 1: return None return self.stack.pop() def push(self, item): self.stack.append(item) def size(self): return len(self.stack) def peek(self): return self.stack[self.size() - 1] def isEmpty(self): if len(self.stack) < 1: return True return False class Calculator: def __init__(self): self.__expr = None…arrow_forwardMain Program:The main program will read in and print three integer values, representing SAT scores. Then the main program will call the method isitavalidgroup() to determine whether or not this group is valid. In either case, the main program will print the result of the method call (and add to the appropriate counter – discussed below). In more detail: If the method isitavalidgroup() says this is a valid group, the main program will print a message, add to the counter of valid groups, and call the method classify(). However, if isitavalidgroup() says the group is not valid, the main program will print a message, add to the counter of invalid groups, and go back to read the next group. Be sure to skip a few lines on the output sheet between groups. (And somewhere add to the counter of total groups.) The main program will continue this process for the entire set of data. When the main program runs out of groups of three values (you must decide when this occurs), print the final values…arrow_forward

- Exercise 3: Write a program to simulate an experiment rolling two six sided "fair" dice. Allow the user to enter the number of rolls of the dice to simulate. What percentage of the time does the sum of the dots of the dice equal eight in the ● simulation?arrow_forwarda. Plan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—$550 for a health policy or $225 for an auto policy. Display the results for each policy. b.Modify Exercise 9a so that the premium-setting method calls one of two additional methods—one that determines the health premium or one that determines the auto premium. The health insurance method asks users whether they smoke; the premium is $550 for smokers and $345 for nonsmokers. The auto insurance method asks users to enter the number of traffic tickets they have received…arrow_forwardCreate a program that will count the number of numeric characters in an input string. The program should be able to ask the user for the input string and should be able to display the number of numeric characters on the screen. For this exercise, you should create your class to handle the different operations. Remember that any input/output operations should be done in the main method while all calculations should be done inside the class. Remember that you need to apply encapsulation in your class.
