- Design an application that declares an array of 10 StockTransactionobjects. Prompt the user for data for each object, and then display all the values. Design an application that declares an array of 10 StockTransactionobjects. Prompt the user for data for each object, and then pass the array to a method that determines and displays the two stocks with the highest and lowest price per share.Code a called method that takes two parameters, an array of double as reference type and a double value. In the method, manipulate the argument by incrementing the value of the array. Note that you are not required to manipulate the entire array.void Date: addDays (int n); void Date: subtractDays(in n); The addDays method will add n number of days to the current date that's stored in Object's data. For example, object hold 4/21/2022 as the date and if user of this object calls addDays (10) method, it will add 10 days to 4/21/2022 giving a new date of 5/1/2022. There can be more complicated scenarios if you add a lot of days (for example hundreds of days) due to possible rollover of year and months. You can limit number of days to be added to 100. Just like addDays, subtractDays method will subtract number of days from the current date. Provide implementation of both functions in the class. Also modify your main function as follows:

- 1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…JAVA Include Code Comments create a public class named ArrayUtility In ArrayUtility class, create a public static method toString that receives an array of int's, a start string, a separator string and an end string.
