i need to return a 2d array from a method containing data from a csv file
this is my code below:
Step by step
Solved in 2 steps with 1 images
- You have square tiles with a side length of ⅓ inch Draw a 4 x 5 array using the square tiles. What are the dimensions of the rectangular array?Provide a code segment that creates an arraylist of three integers and prints these values on the screen. Then add two more integers and print out the last integer on the screen. Note: You are free to choose integers.How would I add the following data (country and data) into an ArrayList? I keep getting an ArrayIndexOutOfBoundsException
- Write a code to print a 3D array?A class with 10 students will take 3 exams. Use 3 arrays to hold the scores for each student and another array to hold the average of the 3 exams for each student. Print a table with scores and the average. SAMPLE OF HOW THE OUTPUT SHOULD BE STUDENT EXAM 1 EXAM 2 EXAM 3 AVERAGE 1 2 3* Use a javascript file to create an array called numArray that holds the numbers 1 through 50. ( [ 1, 2, 3, 4, ... 50 ] ). Use the map() method on the array and an arrow function to transform the array into 50 multiples of 5 ( [ 5, 10, 15, 20, ... 250 ]. (Make sure you assign the result of the mapping back to the numArray array itself in this and the following steps.) Print the result to the console. Then use the map() method with an arrow function to set all multiples of 3 to zero ( [ 5, 10, 0, 20, 25, 0, 35, 40, 0, ... ] ). Print the result to the console. Then use the map() method to subtract 1 from all multiples of 10 that are greater than 1 ( [5, 9, 0, 19, 25, 0, 35, 39, 0, ... ] ). Print the result to the console.* numArray should hold this final result.
- This code is in java.Your friend’s photo editing software has stopped working so you volunteer to help. She wants all the pictures reversed in the horizontal direction along the y-axis so that items on the left side of the picture are now on the right side, and vice versa. Pictures are stored as 2-D arrays, where each “pixel” stores a single brightness value. In other words, you need a method that will take a 2-D array and reverse its columns so that the first becomes the last, the second becomes the second to last, and so on. Given the following starter code, write the method to help your friend.JavaScript ============================================================================ Use the map() method to create a new array with each word capitalized. Use an arrow function with the map() method to access each word in the array. Use string manipulation to capitalize the first letter of each word. Use the map() method again to create an array of word lengths. Use an arrow function with the map() method to access each word in the array. Use the length property of the string to find the length of each word. Use the map() method once more to create an array of objects with each word and its length. Use an arrow function with the map() method to access each word in the array. Create an object with a "word" property that is set to the current word and a "length" property that is set to the length of the current word. Use console.log() to print out the new capitalized word array, word length array, and object array.…The editTemperatures() method takes in two parameters: integer array tempData and integer numMore. Complete editTemperatures() to create a new array called arrayCopy with the same elements as tempData, and the size increased by numMore. Ex: If the input is: 10 48 49 18 3 then the output is: 10 48 49 18 0 0 0 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 Scannerscnr=newScanner(System.in); int[] degreesFahrenheit=newint[4]; intinput; inti; for (i=0; i<degreesFahrenheit.length; ++i) { degreesFahrenheit[i] =scnr.nextInt(); } // Read number of values to increase array size by input=scnr.nextInt(); degreesFahrenheit=editTemperatures(degreesFahrenheit, input); for (i=0; i<degreesFahrenheit.length; ++i) { System.out.print(degreesFahrenheit[i] +" "); } } }
- Write a static method blur(double[][]picture) that you could use on a part of a picture file to obscure a detail such as a person’s face or a license plate number. This method computes the weighted averages of the values in picture and returns them in a new two-dimensional array. To find a weighted average of a group of numbers, you count some of them more than others. Thus, you multiply each item by its weight, add these products together, and divide the result by the sum of the weights. For each element in picture, compute the weighted average of the element and its immediate neighbors. Store the result in a new two dimensional array in the same position that the element occupies in picture. This new array is the one the method returns. The neighbors of an element in picture can be above, below, to the left of, and to the right of it, either vertically, horizontally, or diagonally. So each weighted average in the new array will be a combination of up to nine values from the array…In java, please read the text file as array. Then, replace the null with 0 and calculate the sum of the new students in ABC University.Example of text file: (university,year,total_students,new_students,new_staff,ABC, 2000, 3457, , ,ABC, 2001, 3675,218, ,EFG, 2000, 2389,602, ,EFG, 2001, 2785,396, 65,)Use a two-dimensional, multi-dimensional array and pass it to a method and receive it back. You will create the array, add data, send it to a method to be updated and return it.
