Assignment
A scientist has developed a mathematical model for a physical process, and he wants to check how
good is model is. To evaluate the correctness of his model, he wants to test the results of his model
under certain parameters and compare them with experimental results.
Write a program that first reads the number of tests (testCount) as an int followed by the results of
each test according to the model as a double array (testModel) and finally the results of each test
according to experiments as a double array (testExperiment). Then, the program should calculate
the error of the model by evaluating the average of the absolute values (i.e., mutlak değer) of the
differences between the model result and experimental result (see formula below) using a function.
ItestModel,- textExperiment,

NOTE: Individual absolute value of the difference between the model value and the experiment value
calculations MUST be done in the function. Every other functionality MUST be done in…

In this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array.
Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example,
• each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines;
• all values are in one line that can be read as a string. Then you must handle the parsing of the string;
• all values are in one line separated by a delimiter. Then you must handle a line with delimiters.
Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…

- Exercise 2: We are tasked to write a program that shows some information about 12 persons: first name, last name and telephone number. To do this, we have to create 3 arrays and fill them by the information wanted (first name, last name, phone number) respectively. In order to do some changes on this information, we can create a counter to specify the index of the information we want to change or to update; each index is referred to the each one of the people that we need to save their information.arrow_forwarddo in javaarrow_forwardQ2.

- JAVA Your teacher has created two arrays, each holding the results of tests, say Test 1 and Test 2. You need to create a new array which holds the averages of these two tests. You may assume that the first element of the first test array refers to the student who also has the grade in the first element of the second test, and the last element in each array are the grades the last student earned for each test. All students received grades for both tests, meaning both test arrays are of the same length. Complete the method, named makeAverage, in the class named Grades.java. There are two parameters to this method: the first is the integer array representing the grades of the first test, and the second is the array containing the grades of the second test. The new average array should be returned by the method. The grades should be treated as double variables. For example, consider the test grades for the five students in the following arrays: [ 87 ] [ 91 ] [ 76 ] [ 76 ] [ 94 ]…arrow_forward2. A store owner wants the total sales for 2020.
