Simulate binary search Use array {1, 2, 3, 4, 5, 6, 7} to simulate binary search of 3. For each iteration, you need to write down the value of first, last, and middle after the execution of this statement: middle = (first + last) / 2 follow the loop until you get the search result. After you are done, update the BinarySearchDemo.java class to use this array for search. Compare the print out result to your simulation result.

Simulate binary search
Use array {1, 2, 3, 4, 5, 6, 7} to simulate binary search of 3.
For each iteration, you need to write down the value of first, last, and middle after the execution of this statement:
middle = (first + last) / 2
follow the loop until you get the search result.
After you are done, update the BinarySearchDemo.java class to use this array for search. Compare the print out result to your simulation result.

- Write this program in Java using a custom method. Implementation details You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists. Use an array of strings to store the 4 strings listed in the description. Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below: determine the fruits to display (step 3 below) and print them determine if there are 3 or 4 of the same image display the results update the customer balance as necessary prompt to play or quit continue loop if customer wants to play and there's money for another game. Use the Random class to generate a random number between 0 and 3. This random number will be an index into the array of strings. Add the string at that index to an…Exercise 1: Write a program that generates a sequence of 20 random values between 0 and 99 in an array, prints the sequence, sorts it, and prints the sorted sequence. Use the sort method from the standard Java library. Exercise 2: Write a program that stores a list of countries: "Egypt", "Switzerland", "Argentina", "Spain", "Portugal", "Luxemburg", etc. Initialize your array with a single statement. Then print out the array. Use the sort function as before to sort the countries in alphabetical order. Reprint your array. Exercise 3: Implement exercises 1 and 2 using ArrayList. Use the Collections.sort method for sorting. After you have printed and sorted your results, then append an additional element to each list and reprint your ArrayLists. Notice that the new items will appear just at the end and will not be sorted. Resort and print out the new ArrayLists again. To clarify, you should print out your ArrayLists after your first sort, after adding items with the…Write a hangman game that randomly generates a word andprompts the user to guess one letter at a time, as presented in the sample run.Each letter in the word is displayed as an asterisk. When the user makes a correctguess, the actual letter is then displayed. When the user finishes a word, displaythe number of misses and ask the user whether to continue to play with anotherword.

- only for-loops, if statements, and arrays Write a program in java that uses that creates a 30-element array of random integers to represent Fahrenheit temperatures, ensuring that all temperatures range from 10 to 75, inclusive. Then execute a custom method with the array as its only argument. The method should begin by using a loop to print the array in 6 rows and 5 columns, with all columns being seven characters wide. Duplicates are okay. This same loop should determine how many temperatures in the array are below freezing. Use this figure to declare an new array of integers named freezing. Process the array again, but this time with a foreach loop, and add the freezing temperatures to the freezing array. Return this new array back to main. Report the number of temperatures that were below freezing, sort them, and print them all on one line separated by spaces.1. Declare an array to hold eight integers. Use a for loop to add eight random integers, all in the range from 50 to 100, inclusive, to this array. Duplicates are okay. Next, pass the array to a method that sorts the array and returns another array containing only the largest and smallest elements in the original array. Print these two values in main. Then use a foreach loop to display all elements of the sorted array on one line separated by a single space. This latter loop should also count the odd and even numbers in the array and determine the sum of all elements in the array. SAMPLE OUTPUT The lowest element is 59 The highest element is 96 Here is the array 59 64 76 77 80 88 91 96 Evens: 5, odds: 3 Total: 6311. Declare an array to hold eight integers.

The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).
