getListRowIndices Method public static java.util.ArrayList getListRowIndices​(int[][] array, int rowLength) This method returns an ArrayList with the indices of rows of the two-dimensional having a length that corresponds to rowLength. You may only use one auxiliary method. The method should create an ArrayList that is passed to the auxiliary in order to place the indices (if any). If no indices are found, an empty (size of 0) ArrayList will be returned. You can assume the array parameter will not be null and every row of the two-dimensional array has an array with a size of at least 0. Your implementation must be recursive and you may not use any loop construct. Do not use ++ or -- in any recursive call argument

JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the...

Please help with the following: JAVA use simple arrays no hashcode try and keep it as simple as possible The problem is Java Intersection of Three Sorted Arrays use simple array to solve the following: // a1 {1,2,5,10}// a2{4,5,9}// a3 {1,5,7,9} the number 5 should be the one to show up

17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

X42: frontPiece Given an int array of any length, return a new array of its first 2 elements. If the array is smaller than length 2, use whatever elements are present. Examples: frontPiece ({1, 2, 3}) -> {1, 2} frontPiece ({1, 2}) -> {1, 2} Your Answer: Feedback Your feedback will appear here when you check 1 public int[] frontPiece(int[] nums) 2 { your answer. 3 4 }

JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.
