Use only k, currentMembers, nMembers, and isAMember.Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).

Create a java version of this game with the following requirements. Extend the JPanel class and create an array of 52 cards. Add four sets of numbers from 1 to 10. Use J for Jack, Q for queen, K for king, and A for ace. Jack through king will have a value of 10, and the ace will have a value of 11. Deal two cards to the user and two cards to the computer. Do not show the value of the computer's first two cards to the user. Add buttons Hit, Stay, and Reset. If the user selects the "Hit" button, randomly select one of the cards from the array, and give it to the user. (After selecting a card, do not reuse this index during the rest of the game.) If the dealer has less than 21, "hit" the dealer, too. When the user selects the "Stay" button, add up the card values. The winner is the person who is closest to 21 without going over. Name the class Blackjack.java.RU Rotten Tomatoes . 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 sequence. java RURottenTomatoes 3 2 5 2 3 3 4 1 0 1 0 5 2 1 3 3 2 4 1 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).

Use thelength property to print the elements.5) Print the elements of the array from last to first using a loop. Use thelength property to print the elements.Program71.java Write a program that creates a 32-element array of random integers all from 1 to 100, 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 elements in 4 rows and 8 columns, with all columns being five characters wide. Duplicates are okay. This same loop should determine how many integers in the array are odd numbers. After this loop ends, use this figure to declare a new array of integers named odds. Process the array again in the method, but this time with a foreach loop, and add the odd integers to the odds array. Return the odds array back to main. In main, report the size of the array and sort it ascending. Finally use a while loop to print the odd integers all on one line separated by spaces.Program72.java See Section 7.13 and watch the Command Line Arguments (2:08) video (video image below).
