Solved in 3 steps with 2 images
- This is the process of actually creating the array object and associating it with the array variable. Give a one-word answer.Image one is my file or you can create ur own file as long as it's similar to mine. image 2 is my program I want to write a 4th method(method 4) and the spec is: A method to count the occurrences of each value in an array takes one parameter, an array of integers returns an array containing the number of times each value occurs in the parameter array. Also should call method 3 from method 4Hint: The general idea of this method is using an array with length maxVal+1(maxVal should get from method 3 already) to save the occurrences of each number. For example, if number 44 occurs 3 times in the file, your array should have a value 3 stored at index 44.Create 1 method to output the list of numbers. Output the list of numbers input by user. Output the average of all the numbers. Attach Snipping photos of source code and output. Task 2 Update above program. Create a Method that will return the largest element in the array. Attach Snipping photos of source code and output.
- Create an ArrayList, Named it Husnain that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say so. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than onceWrite a program that creates a 2-D array initialized with test data . Use any primitive type of data EXCEPT int (Integer). The program should have all methods in the problem. getTotal - This method should accept a two-dimensional array as its argument and return the total of all the values in the array. getAverage - This method should accept a two-dimensional array as its argument and return the average of all the values in the array. getRowTotal. - This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. getColumnTotal - This method should accept a two-dimensional array as its First argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column.…JAVA LANGUAGE Create an ArrayList, Name it YourRegNoandName that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say “FOUND”. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than once. ALSO SCREENSHOT THE OUTPUT
- Use a two-dimensional, multi-dimensional array and pass it to a method and receive it back. You will create the array, add data, send it to a method to be updated and return it.Write a program that do the following: Ask the user to input his/her first name and store it in a String variable. Create an ArrayList with the type String. Each letter of the inputted name should be stored in a separate element of the ArrayList. Print the ArrayLists. Note: Your answer should have the code as text, as well as a screenshot of the code with the output. The inputted name should be your first name. Name : RababCreate integer ArrayList. Ask user input for integer, which is used to append the elements for that number of times. Create a Java method named "repetition" which will pass two parameters – ArrayList and integer entered by user. In the method, elements are replicated for the number of times based on the value of the integer. For example, If you have an ArrayList with the values [21,25, 5] and the user inputs 3, the repetition method should print the value -- [21,25, 5,21,25,5,21,25,5]
- Write a java application which initializes an array with ten random integers between 1 and 6. Write two methods: 1. arraySwap: this method should accept an integer array and swap the first and the last item. 2. findMinimum: this method should accept the array and return the minimum value of that array You should comment and follow javaDoc for both methods. Your main method should test each of these methods.Define an array to be a 121 array if all elements are either 1 or 2 and it begins with one or more 1s followed by a one or more 2s and then ends with the same number of 1s that it begins with. Write a method named is121Array that returns 1 if its array argument is a 121 array, otherwise, it returns 0. There is one additional requirement. You should return 0 as soon as it is known that the array is not a 121 array; continuing to analyze the array would be a waste of CPU cycles. If you are programming in Java or C#, the function signature isint is121Array(int[ ] a) If you are programming in C or C++, the function signature isint is121Array(int a[ ], int len) where len is the number of elements in the array a. Examples a is then function returns reason {1, 2, 1} 1 because the same number of 1s are at the beginning and end of the array and there is at least one 2 in between them. {1, 1, 2, 2, 2, 1, 1} 1 because the same number of 1s are at the beginning and end of…JAVA I cannot figure this one out no matter what I do I cannot get it to run. Please write it in a student way not in an too advance way. Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.
