Concept explainers
You are to construct a 2D matrix of booleans of the given size. You should fill the matrix with false values. Then create a Random object initialized with the provided seed and fill the interior of the matrix row by row from left to right within each row. Do not place a new value in the first or last row, or the first or last column of the matrix as they may not contain an entity (and hence should remain false). You should use the nextBoolean method of the Random object to get each value. This will generate a matrix in which each value (other than on the edge) is equally likely to be true or false. Finally, print the matrix by printing a ’-’ character for each false and a ’#’ for each true. Include the outside rows and columns in the printing. Print a space after each ’-’ character or ’#’ character. Figure 1 shows a sample input and corresponding output. 6 8 7 (a) Input (6 rows, 8 columns, seed 7)

- Compare and contrast the array and arrayList. Give at least one example that describe when to use arrayList compared to an array.arrow_forward1. Create a script that will take 4 vertices (total 8 numbers) then make decision whether those vertices form a square, a rectangular, a diamond (A.K.A Rhombus), a parallelogram, or just a quadrilateral. Also, the area of the shapes if the shape is a square or rectangular. [CREATE AN ARRAY FOR 4 VERTICES (TOTAL 8 NUMBERS, THEN REPEAT THE SAME PROCEDURE. The WHOLE COMPUTATION NEEDS TO BE DONE BY ACCESSING ELEMENTS IN THE ARRAY .) Taking values for the ARRAY has to be done within main(). But computation and displaying the result should be done with the USER DEFINED FUNCTION!)arrow_forwardNeed help with 2d array problem and getting the display result asked in the problem.arrow_forward
- Access PyCharm. Then, demonstrate how to work with the complex objects as outlined below. Take appropriate screenshots (with descriptions) as needed. Create functions that take five arguments and multiplies them according to the type of object they are: Scalar Vector Matrix Plot each of the functions that you have constructed.arrow_forwardCreate a 2D array of size 14x14 having same values ranging from 0 to 255 in each row. You are free to specify the values of this array. For instance, consider a 3x3 array as;Array [3] [3]= {{12,12,12}, {75, 75, 75}, {247, 247, 247}}12, 75, and 247 pixel values are specified in a way that they are in a range of 0 to 255 and they are same in a row.Write a code namely arraytoimage.c using any pgm (portable gray map) format image that represents an image in a text file in which each pixel is represented by a number ranging from 0 and 255. In this code, write:-P2 (magic number)-Width and height of the image-Maximum grayscale value-Gray scale intensity values you specify in the arrayin an order to this imagearrow_forwardThe "dynamic array" data structure is used as the basis of Java's ArrayList library class. Describe this data structure and explain how it achieves (amortized) constant-time adding of elements, while also giving constant-time random access of elements. As part of your answer, make sure to explain what "amortized" means for the data structure.arrow_forward
- Determine if the following statement are true or false screen shot shows the text's SortedArrayCollection and ArrayCollection When comparing two objects using the == operator, what is actually compared is the references to the objects. When comparing two objects using the equals method inherited from the Object class, what is actually compared is the references to the objects. The text's sorted array-based collection implementation stores elements in the lowest possible indices of the array. The text's array-based collection implementation stores elements in the lowest possible indices of the array.arrow_forwardQuestion in the picture below.arrow_forwardYou are given a dictionary of names and the amount of points they have. Return a dictionary with the same names, but instead of points, return what prize they get. "Gold", "Silver", or "Bronze" to the 1st, 2nd and 3rd place respectively. For all the other names, return "Participation" for the prize. Examples awardPrizes({ "Joshua" "Alex" : 39, "Eric": 43 }) → { } "Joshua" "Gold", "Alex" "Bronze", "Eric" : "Silver" awardPrizes_({ "Person A" 45, 1 "Person B": 2, "Person C" 3, "Person D" 4, 102 "Person E }} → { "Person A" "Person B" (Ctrl) "Participation" "Participation", "Person C" : "Bronze", "Person D" : "Silver", "Person E" "Gold"arrow_forward
