This program can be done using command line arguments and by using random() in java.lang.*

A university is analysing students' academic performance in a course using an application. As shown below, the application generates a list of final marks and an academic performance report: The following information is required to generate the final mark listing and academic performance report: Course details The course details to be stored in the program include a list (array) of final marks, number of students, a list (array) of the distribution of frequencies of grades. The final marks: 75B+ 79B+ 88A 96A+ 90A+ 80A 76B+ 76B+ 79B+ 76B+ 75B+ 91A+ 92A+ 82A 84A 76B+ 97A+ 93A+ 95A+ 82A 78B+ 81A 81A 82A The final marks are stored in a text file named marks.txt.

Real World Example You work at a car dealership and your boss asks you to get the color of a car. He tells you the parking lot to get it from (the object you're searching) and then writes exactly where it is. row1 [0].color, he could also give you this direction as an array ["row1", "[0]", "color"]. If there is no color he tells you to tell him "no color found" (the default value). You follow his instructions and return "red". Examples = { "a": [{ "b": { "c": 3 } }] } var object get (object, "a[0].b.c") → 3 get (object, ["a", "0", "b", "c"]) -3 get (object, "a.b.c", "default") "default"
You have made a device that automatically measures both distance from a magnet and the magnetic field strength at that distance. The device sends the pair of data to your computer as a pair of real numbers. However, the device moves back and forth as it takes data, so neither the field measurement nor the distance measurement arrives in ascending or descending order. Write a code vector_sort that receives a two-dimensional array of numbers and sorts them based on either the first column or the second column (this must be an input to the function. The function must also either sort high-to-low or low-to-high, based on an input value. Write a main function that can read up to twenty pairs of data. The main function must also input whether you want to sort high-to-low or low-to high. It must also input whether you want to sort on magnetic field or distance. Finally the code must print the pair data as originally entered and then, after calling vector_sort, the ordered pair data. C Program

Display the names and the number of characters in the name (without the space) as a table (use printf) Name Number of lettersDimo Ivanov 10 3. Get an array first_letters of type char [], containing the first letters of the names. Display it with Arrays.toString () 4. Get the arrays of names and surnames containing initial and second names, respectively (first determine the position of the space in the previous name with the indexOf () method of the String class). Display the arrays. 5. Sort the first_names array

Write a program that simulates a lottery. The program should have an array of five integers named winningDigits, with a randomly generated number in the range of 0 through 9 for each element in the array. The program should ask the user to enter five digits and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many digits match. For example, the following shows the winningDigits array and the Player array with sample numbers stored in each. There are two matching digits, elements 2 and 4. WinningDigits 7 4 9 1 3 player 4 2 9 7 3 Once the user has entered a set of numbers, the program should display the winning digits and the player’s digits and tell how many digits matched.
