- 7.21 LAB: Random values use Java. In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3(). Then write the following 2 instance methods: setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive). getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3" Ex: If the input is: 15 20 the output may be: Random values: 17 15 19 where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range. import java.util.Scanner; public class LabProgram {// main method used to test your codepublic…????????: Implement the design of the Pizza class so that the following output is produced: [Your code should work for any number of parameters added in the set_toppings_info method] # Write your codes here. print("Pizza Count:", Pizza.pizza_count) print("=======================") p1 = Pizza("Chicken") p1.set_toppings_info(25, 1, 4, 0) p1.display() print("------------------------------------") p2 = Pizza("Olives") p2.set_toppings_info(15, 1.5, 0, 0) p2.display() print("------------------------------------") p3 = Pizza("Sausage") p3.set_toppings_info(50, 5, 2, 0) p3.display() print("=======================") print("Pizza Count:", Pizza.pizza_count) Output: Pizza Count: 0 ======================= Toppings: Chicken 25 calories 1 g fat 4 g protein 0 g carbs ------------------------------------ Toppings: Olives 15 calories 1.5 g fat 0 g protein 0 g carbs ------------------------------------ Toppings: Sausage 50 calories 5 g fat 2 g protein 0 g carbs ======================= Pizza…How to pass this test case?

- _4.1g Write a Java class that would match a string. The class has method match with String as a return type. It accepts two inputs: the phrase/sentence string (text) and the pattern string (word). This method finds the first (or all) instances of the pattern in the text and changes that word in all uppercase and return the new phrase. Method countOccurence accepts a phrase/sentence and a pattern string and returns its number of occurrences. Add a main method that will allow the user to input the phrase/sentence and pattern. Call method match and countOccurence. See test case below. Sample Input: Text string: You will always have my love, my love, for the love I love is as lovely as love itself. Pattern string: love . .11.8 At what point does the Java environment complain about your passinga non-Comparable value to an OrderedVector?11.9 Write the compareTo method for the String class.11.10 Write the compareTo method for a class that is to be ordered by a field,key, which is a double.

- BJP4 Exercise 4.16: printPalindrome Write a method called printPalindrome that accepts a Scanner for the console as a parameter, and prompts the user to enter one or more words and prints whether the entered String is a palindrome (i.e., reads the same forwards as it does backwards, like "abba" or "racecar"). If the following Scanner object were declared: Scanner console = new Scanner(System.in);printPalindrome(console); The resulting output for a call where the user types a palindrome would be: Type one or more words: racecar racecar is a palindrome! The output for a call where the user types a word that is not a palindrome would be: Type one or more words: hello hello is not a palindrome. For an added challenge, make the code case-insensitive, so that words like "Abba" and "Madam" will be considered palindromes.6.20 LAB: Fibonacci sequence Java? The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which has an index, n, as parameter and returns the nth value in the sequence.

Define a method named createAcronym that takes a string parameter and returns the acronym of the string parameter. Append a period (.) after each letter in the acronym. If a word begins with a lower case letter, don't include that letter in the acronym. Then write a main program that reads a phrase from input, calls createAcronym() with the input phrase as argument, and outputs the returned acronym. Assume the input has at least one upper case letter. Ex: If the input is: Institute of Electrical and Electronics Engineers the output should be: I.E.E.E. Ex: If the input is: Association for computing MACHINERY the output should be: A.M. Although the letters ACHINERY in MACHINERY are upper case, those letters are omitted for being a part of the word MACHINERY. The program must define and call a method:public static String createAcronym(String…
