Starting Out with Java: From Control Structures through Data Structures (3rd Edition)
- Problem2: 2D Arrays Define a 2D array using Java code that takes from a teacher the total number of rows and the total number of columns. Then let the teacher fill the array by students IDs and courses marks for each student. And print the following: 1- Print the array. 2- Print the marks that are less than 50 (mark < 50)arrow_forwardProblem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not foundarrow_forwardprogramming used: javaarrow_forward
- Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forwardLook at the following array definition. int values[10];A) How many elements does the array have?B) What is the subscript of the first element in the array?C) What is the subscript of the last element in the array?D) If an int uses four bytes of memory, how much memory does the array use?arrow_forwardint Marks [20] = { 70,85, 60, 55,90,100,50}; For the above code, answer the following questions in the space provided below: 1. Find the size of Marks array. 2. How many number of elements are present in Marks array ? 3. Find the index value for last element in array 4. Find the index value for the element 60 5. Find the value of Marks[2] + Marks[0] in Marks array.arrow_forward
- The index type of an array can be any data type. True or false?arrow_forward1. Shift Left k Cells Use Python 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 ]arrow_forwardJAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method. Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2 Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average. If the number of elements in an array is odd don't modify the last number of the array. Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…arrow_forward
- Look at the following array definition.int numberArray[9][11];Write a statement that assigns 145 to the first column of the first row of this array.Write a statement that assigns 18 to the last column of the last row of this array.arrow_forwardIn visual basic Print out the last value in a single-dimensional array.arrow_forward23. True or False: The bracket of the array type can be associated with the element type or with the name of the array. float[] prices; -> float prices[]; False True Give an explanation for the answer.
