Write a java program. Write a method getDecimalArray that recieves an array named octalArray containing values 0, 121, 3232, 0, 4565, 67654, 79867. The task is to compute the decimal representations of all the numbers in octalArray and store the decimal representations in another array named decArray with int datatype. Hint: You'll need to implement nested loops, outer for the traversal of octalArray and inner for the computayion of decimal representation of current octal number.For 121 = (1*8¹)+(2*8¹)+(1*8⁰)

Write the Java method averageOfDoubles that is passed an array of double values, and returns the average of the array values.You can assume the array length is a positive integer.

Please use Java for the solution

The java program ArrayTest.java is intended to do the following: • Fill the array a with integer values input from the file ints.txt. • (Shift-right) Shift the elements of a to the right one position and put the last element of array a in the first position in a (wrap around). Example: if a originally contained (1, 2, 3, 4} then the resulting array a would be (4, 1, 2, 3} What command would be given on the command line to redirect the input to the program ArrayTest to come from the text file ints.txt?

Write a Java program that will allow the user to play a hangman game repeatedly until theychoose to stop. The game should randomly choose a secret word from a pre-set list of wordsfor the user to guess. Store the list of words available for play in an array so you can randomlychoose them by index during game play.During a turn, the user will guess one letter at a time. Each letter in the secret word shoulddisplay as an asterisk until the letter is guessed by the user. When a correct letter is guessed,the letter should be displayed in the correct position in place of the asterisk. The user hangshimself with the 8th wrong guess and loses the game.Make a character array to hold the characters and asterisks representing the word beingguessed. You can change the contents of this array as the letters are guessed and revealed. Inother words, this array can be used to display the current state of the secret word each round.Here is the list of words the game should choose from for the secret…

Devise an algorithm that detects whether a given array is sorted into ascending order. Write a Java method thatimplements your algorithm. You can use your method to test whether a sort method has executed correctly. Ensure that your program has a test class

Write a program RURottenTomatoes.java that creates a 2 dimensional integer array of movie ratings from the command line arguments and displays the index of the movie that has the highest sum of ratings. Ratings range from 1 to 5 (inclusive). The rows of the 2D array correspond to movie reviewers and the columns of the 2D array correspond to movies. The reviewer at index 2 gave movie at index 0 a rating of 4. Take a look at the following example for an explanation on the command line arguments sequenc.  The first argument corresponds to the number of reviewers and the second argument corresponds to the number of movies (the dimensions of the 2D integer array). Following are the movie ratings in a row-major order. This means that the first row is filled first, then the second row, etc. In the example above there are 3 reviewers and 2 movies, and the program displays 0 (zero) because the movie at index zero has the highest sum of ratings (movie 0 has sum of ratings equals to 12 while…

Write a class ArrayClass, where the main method asks the user to enter the four numbers. Create a method printArray that prints the array whenever required (use Array.toString method). Make the program run as shown in the Sample Run below. Use Array.sort, Arrach.bianrySearch, Array.equals

Use java.

Write a Java program with a single-dimension array that holds 10 integer numbers and identify the maximum value of the 10 numbers. Next sort the array using a bubble sort and display the array before and after sorting.
