- Shift Left k Cells Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]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…a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b. Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4] b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array. class Main {public static int[] createArray(int a, int b) {}public static void main(String[] args) {}}
- How many elements are in the array? int[][]userVals=newint[2][4]; a. 2 b. 4 c. 6 d. 8 THIS CLASS TEACHES JAVAIndicate what values would be stored in the array after the method arrayMystery executes if the integer array is passed as a parameter to it. Note: The Array elements must be separated by comma in curly braces. For example, if the result array contains 3, 5, and 2, it should be written as {3,5,2}. arrayMystery(a4, 4); arrayMystery(a5, 6);int[] array = { 1, 4, 3, 6 }; What would be a proper syntax to access 3 from this array?
- If you have the following statements: int i j; int ctr = 0; int myArray[2][3]; for (i=0; i<3; i++) for (j=0; j<2; j++) { myArray[ j ][ i] = ctr; ++ctr; } The value of the element myArray[1][2] after executing the above statements:1. An array is a container that holds a group of values of a 2. Each item in an array is called an 3. Each element is accessed by a numerical 4. The index to the first element of an array is 0 and the index to the last element of the array is the length of the 5. Given the following array declaration, determine which of the three statements below it are true. int [] autoMobile = new int [13]; i. autoMobile[0] is the reference to the first element in the array. ii. autoMobile[13] is the reference to the last element in the array. ii. There are 13 integers in the autoMobile array. 6. In java new is a which is used to allocate memory 7. Declare a one-dimensional array named score of type int that can hold9 values. 8. Declare and initialize a one-dimensional byte array named values of size 10 so that all entries contain 1. 9. Declare and initialize a one-dimensional array to store name of any 3 students. 10. Declare a two-dimensional array named mark of type double that can hold 5x3…IN C++ Write a method that lets you insert a number anywhere in an array that is already full. For instance, if you have an array of size 5: 3,6,1,2,0. You should be able to insert the number 9 in some desired/specified position. E.g 3,6,1,9,2,0.
