- Write the followingmethod that tests whether a two-dimensional array has four consecutive numbersof the same value, either horizontally, vertically, or diagonally:public static boolean isConsecutiveFour(int[ ][ ] values) Write a test program that prompts the user to enter the number of rows andcolumnsof a two-dimensional array then the values in the array, and displays trueif the array contains four consecutive numbers with the same value. Otherwise,the program displays false. Here are some examples of the true cases:An array with more than one index is called a/an: partially filled array. O multidimensional array. O bidirectional array. one dimensional array.1. What is right way to Initialize array? A. O int num[6] = { 2, 4, 12, 5, 45, 5 }; B. O int n{} ={ 2, 4, 12, 5, 45, 5 }; C. O int n{6} = { 2, 4, 12 }; D. O int n(6) = { 2, 4, 12, 5, 45, 5 };
- Declare an array that represents 100 students. Assign the examscores between 0 and 100 randomly into this array. Write amethod and display that assigns letter grade equivalents of theexam scores to a second array. Display the number ofunsuccessful students.The grade scala is as follows:100 – 90 : A89 – 80 : B79 – 70 : C69 – 60 : D59 – 0 : F (unsuccessful) (Write in java)Which statement is correct?int[] n = { 16, 3, 7, 18, 21 };int[] m = n; Question 6 options: The variable m references a new array that is an exact of copy of n. Both n and m are variables that reference the same array. This is how you copy an existing array to a new one. The contents of n is copied to m.Write the following method that returns the locationof the smallest element in a two-dimensional array.public static int[] locateSmallest(double[][] a)The return value is a one-dimensional array that contains two elements. Thesetwo elements indicate the row and column indices of the smallest element in thetwo-dimensional array. Write a test program that prompts the user to enter a twodimensionalarray and displays the location of the smallest element in the array.Here is a sample run: Enter the number of rows and columns of the array: 3 4↵EnterEnter the array:23.5 35 2 10↵Enter4.5 3 45 3.5↵Enter35 44 5.5 9.6↵EnterThe location of the smallest element is at (0, 2)**
- 1. Create an array named arr1 with 20 random numbers between 1 and 10(inclusively). Then produce a new array arr2 based on arr1 as follows: arr2 has the same length as arr1. In arr2, each element is the sum of the corresponding element in arr1 and the previous element of arr1, except the first number in arr2 equals the first number in arr1. For example, If arr1 has the elements: Then arr2 will be: 2 5 19 3 7 6... 2 7 6 10 12 10 13... Please display the two arrays.2DArray method:It will allocate a block of memory which represents a two-dimension arraybased on the input values supplied by the user. Ask the user to enter the number of rows andcolumn for 2D array that the user want to manipulate. The number of rows and columns that theuser enters may or may not define a square matrix (when the number of rows equals the numberof columns). The array will have exactly rows time columns (m * n) elements. It will notcontain any extra or empty cells. Initialize the “matrix” by rows with random number between 1to 100. Pass two arguments by out reference so that you can assign the number of row andcolumns of data to the first and second arguments. This is return 2D array method afterallocating new memory for 2D array and initialize it with random value. Generate randomnumber code in C# as following: Random randnum = new Random( );int number = randnum.Next (1, 101);SwapRow method: it will rotate the data in the matrix in an up/down method such that the…Integer numElements is read from input and represents: • The number of elements in each array. • The number of pairs of integers read from input. Declare two integer arrays, roomIds and serviceFees. Then, read each pair of integers from input. For each pair read, store the first integer into roomlds and the second integer into serviceFees. Ex: If the input is: 3 2 50 4 25 8 40 then the output is: Room id: 2, Fees: $50 Room id: 4, Fees: $25 Room id: 8, Fees: $40 1 import java.util.Scanner; 2 3 public class Cash Records { 4 5 6 8 9 10 11 12 13 14 15 16 17} public static void main(String[] args) { Scanner scnr= new Scanner (System.in); int numElements; int i; numElements = scnr.nextInt (); /* Your code goes here */ for (i = 0; i < numElements; ++i) { System.out.println("Room id: " + roomIds[i] + ", Fees: $" + serviceFees[i]); }
- Write an application that stores nine integers in an array. Display the integers from first tolast, and then display the integers from last to first.The array index can be any integer less than the array size… TRUE OR FALSETableAA.java Write a program that will store a multiplication table in a 2-D array. 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).
