Complete the code by entering the property in the box.Class name: SURNAME_MATRIX Data fields: two(2) q xr arrays where: q = no. of characters of your first name. If q <= 5 then q = q * 2. r= no. characters of your surname. if r<= 5 then r=r*2. Methods: Constructor: initialize two(2) arrays. Value of each element = no. of characters of your fullname * 2.5. fillA1() - populate 2d-Array1 with random numbers. (200 max). seed - default fillA2() - populate 2d-Array2 with random numbers. (5000 max). seed - default addSubA1A2(int flag) - add or subtract the two matrices and display the resultant matrix (size is q xralso). (note: invoke first fillA1() and fillA2()) if flag is nonzero add matrices else subtract matrices. e.g. addSubA1A2(3) <-- add arrays, addSubA1A2(0) <-- subtract arrays toString() - displays the current date once and your fullname k times where kis a random number < 8. Filename: SURNAME_SSE2.java In main(): Create two(2) objects using array of objects and use ALL the methods for each object.
- $cars = array("Volvo", "BMW", "Toyota"); what is cars[0] O Volvo O Toyota2DArray 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.

Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type.

- Suppose theArray is an array of type int. To find the length of theArray, we code theArray._______Lab Goal : This lab was designed to teach you more about sorting. Lab Description : Create a random array of numbers from 1 – 10. Then, move all of the 7s to the front of the array. The order of the other numbers is not important as long as all numbers follow the group of Lucky 7s. Looking at the code for insertion sort and selection sort might be very helpful for this assignment. Arrays.toString() will also be useful. For instance, if you are given the list :: 4 5 6 7 1 2 3 7The list could become – all 7s must be first :: 7 7 6 4 1 2 3 5 Sample Data : Data is all random Sample Output : [1, 10, 9, 2, 8, 2, 5, 6, 10, 7, 9, 8, 6, 7, 2, 7, 6, 10, 5, 3][7, 7, 7, 2, 8, 2, 5, 6, 10, 1, 9, 8, 6, 10, 2, 9, 6, 10, 5, 3] [2, 2, 2, 6, 2, 2, 4, 5, 3, 6, 10, 7, 5, 1, 9, 10, 7, 2, 2, 7][7, 7, 7, 6, 2, 2, 4, 5, 3, 6, 10, 2, 5, 1, 9, 10, 2, 2, 2, 2] [5, 9, 9, 5, 10, 5, 7, 5, 6, 7, 10, 8, 9, 9, 5, 4, 6, 6, 3, 3][7, 7, 9, 5, 10, 5, 5, 5, 6, 9, 10, 8, 9, 9, 5, 4, 6, 6, 3, 3]An array index starts with -1 1 0. 2.
