Suppose we have a 1-D array of Strings such that:• Each string records individual scores for different quizzes for one student.• Each string has the form "d1;d2;d3;.;dn;" where d1 to dn are all double values and they areseparated using the character . Note that there is one ; after the last double value.• Each string contains the same number of double values.Write the method convert that takes a 1-D array of such Strings and an integer n as inputs,where n means the number of double values in each String in the array and returns a 2-D arraycontaining doubie values. In the two 2-D array, each row records scores of one student andeach column contains scores of one exam for all students.For example, if the parameters are ("1:2;3:4;", "5:6:7;8;", "9;10;11;12;") and 4, then the output wouldbe a 3'4 2-D array which has the value ((1.0, 2.0, 3.0, 4.0), (5.0, 6.0, 7.0, 8.0), (9.0, 10.0, 11.0, 12.0).You are supposed to use the provided String library methods to operate these string values.Here is the documentation for String:https://docs.oracie.com/en/java/javase/11/docs/api/java.base/java/lang/String.htmlThe method signature is given below:public static double[] convert(String0 exams, Int n)

Question

Suppose we have a 1-D array of Strings such that:
• Each string records individual scores for different quizzes for one student.
• Each string has the form "d1;d2;d3;.;dn;" where d1 to dn are all double values and they are
separated using the character . Note that there is one ; after the last double value.
• Each string contains the same number of double values.
Write the method convert that takes a 1-D array of such Strings and an integer n as inputs,
where n means the number of double values in each String in the array and returns a 2-D array
containing doubie values. In the two 2-D array, each row records scores of one student and
each column contains scores of one exam for all students.
For example, if the parameters are ("1:2;3:4;", "5:6:7;8;", "9;10;11;12;") and 4, then the output would
be a 3'4 2-D array which has the value ((1.0, 2.0, 3.0, 4.0), (5.0, 6.0, 7.0, 8.0), (9.0, 10.0, 11.0, 12.0).
You are supposed to use the provided String library methods to operate these string values.
Here is the documentation for String:

The method signature is given below:

Problem 1: Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following: The method takes a 2D String array x as a parameter and returns no value. The method should calculate and print the sum of the elements on the major diagonal of the array x. In order to have a major diagonal, the array passed into the method should be a square (n-by-n), if it's not a square your program should handle that situation by throwing an exception. (Do Not worry about ragged arrays) If the array is a square, but there is a non-integer value on the major diagonal, your program should handle that situation by throwing an exception. When handling the exceptions, be as specific as you can be, (i.e. Do Not just use the Exception class to handle all exceptions in one catch block). Make the proper calls to the sumOfDiagonals method from the main method to test your sumOfDiagonals method on all the String arrays provided in the main method.
Assignment 5B: Keeping Score. Now that we know about arrays, we can keep track of when events occur during our program. To prove this, let's create a game of Rock-Paper-Scissors. For those not familiar with this game, the basic premise is that each player says "Rock-Paper- Scissors!" and then makes their hand into the shape of one of the three objects. Winners are determined based on the following rules: Rock beats Scissors Scissors beats Paper Paper beats Rock At the start of the program, it will ask the player how many rounds of Rock-Paper- Scissors they want to play. After this, the game will loop for that many number of times. Each loop, it will ask the player what item they want to use – Rock, Paper, or Scissors. The computer will randomly generate its own item, and a winner will be determined. The game will then save the result as an element of an array, and the next round will begin. Once all the rounds have been played, the program will say "Game Over" and display a list of who…

Please add comment on each line Thank you very much! Write a static method, getBigWords, that gets a single String parameter and returns an array whose elements are the words in the parameter that contain more than 5 letters. (A word is defined as a contiguous sequence of letters.) EXAMPLE: So, if the String argument passed to the method was "There are 87,000,000 people in Canada", getBigWords would return an array of two elements, "people" and "Canada". ANOTHER EXAMPLE: If the String argument passed to the method was "Send the request to support@turingscraft.com", getBigWords would return an array of three elements, "request", "support" and "turingscraft".
Write a method that computes how often each letter A-Z or a-z occurs in a string. Don't distinguish between upper- and lowercase letters. Return an array of length 26. The ith element contains the number of times that the letter 'a' + i or 'A' + i occurs in the string. The string may contain other characters that you should simply skip.
