In JAVA, use a HashMap to count and store the frequency counts for all the words from a large text document. Using file util, please. Then, display the contents of this HashMap with words and frequency count. Next, please create a set view of the Map and store the contents in an array. Sort this array based on key value and display it. Finally, sort the array in decreasing order by frequency and display it as well. Please label your explanation in the code Thank you

Update it to create a class Student that includes four properties: an id (type Integer), a name (type String), a Major (type String) and a Grade (type Double). Use class Student to create objects (using buttonAdd) that will be read from the TextFields then save it into an ArrayList. Perform the following queries on the ArrayList of Student objects and show the results on the listViewStudents (Hint: add buttons as needed): d) Use lambdas and streams to calculate the total average of all Students grades, then show the result. e) Use lambdas and streams to group Students by major, then show the results. 1.

In java please help with the following:

Add a new method to ArrayTools with filter. Make this method accept a String array. Change all the Strings that are longer than 5 characters to uppercase. Write in Java and use test cases 1 & 2 as a result.

Using comments within the code itself, can you provide an line by line explanation of the below JavaScript file? The file itself deals with WebGl and if that helps you. Please and thank you JavaScript file: function mat2() { var out = new Array(2); out[0] = new Array(2); out[1] = new Array(2); switch ( arguments.length ) { case 0: out[0][0]=out[3]=1.0; out[1]=out[2]=0.0; break; case 1: if(arguments[0].type == 'mat2') { out[0][0] = arguments[0][0][0]; out[0][1] = arguments[0][0][1]; out[1][0] = arguments[0][1][0]; out[1][1] = arguments[0][1][1]; break; } case 4: out[0][0] = arguments[0]; out[0][1] = arguments[1]; out[1][0] = arguments[2]; out[1][1] = arguments[3]; break; default: throw "mat2: wrong arguments"; } out.type = 'mat2'; return out; } //---------------------------------------------------------------------------- function mat3() { // v = _argumentsToArray( arguments ); var out = new Array(3); out[0] = new Array(3); out[1] = new Array(3); out[2] = new Array(3);...

Say we are about to build an ArrayList. Your ArrayList should guarantee that the array capacity is at most four times the number of elements. What would you like to do to maintain such a limit on the capacity? What is the benefit of using iterators? Can you describe your first experience of GUIs? And could you describe what is the advantage of using GUIs over Command-Line Interface (CLI) operations?

please use the name, phonenumber and phonebookentry to build this. The three parallel arrays are gone — replaced with a single array of type PhonebookEntry. You should be reading in the entries using the read method of your PhonebookEntry class (which in turn uses the read methods of the Name and PhoneNumber classes). Use the equals methods of the Name and PhoneNumber classes in your lookup and reverseLookup methods. Use the toString methods to print out information. Make 100 the capacity of your Phonebook array Throw an exception (of class Exception) if the capacity of the Phonebook array is exceeded. Place a try/catch around your entire main and catch both FileNotFoundExceptions and Exceptions (remember, the order of appearance of the exception types in the catch blocks can make a difference). Do not use BufferedReader while(true) breaks The name of your application class should be Phonebook. Also, you should submit ALL your classes (i.e., Name, Strip off public from all your class...

The input to this method is supposedly an ArrayList of integers that ranges from 1 to 100, however this is not exactly the case. Sometimes, there will be gaps in the range for example, the range could be: [1 2 ... 7 8 ... 99 100], with missing ranges in between. Find all the missing numbers from the range, add them to an ArrayList, return the ArrayList.------------------------ Below is my code that is failing. It is returning the correct missing numbers but is not going passed the last number from the array. so [4,5,14,16,23,76,89] It is placing all of the missing numbers up to 88 when it should be going to 100 The solution should only return the missing numbers from 1-100. The original numbers from the given array should not be included in the return. How can I only return the missing numbers? ------------------------ public ArrayList<Integer> solution(ArrayList<Integer> nums) {ArrayList<Integer> result = new ArrayList<Integer>();int count =...

Write two methods, myCode() and helloWorld(String[] args). The myCode() method must: 1. Create a String array with these elements: "Hello" "World" 2. Call helloWorld(String[] args) method, using the array you created as the parameter. The helloWorld(String[] args) method must: 1. Replace the word "World" with the word "CityTech".

Exercise #2 Implement an instance method belonging to the IntArrayBag class that takes two input parameters, oldVal and newVal. The method replaces each oldVal element in the array with newVal. Make sure to include the method header.

In java, Write a method void popMult(int k) for the ArrayBoundedStack class which will pop k items from this. Throw a StackUnderflowException and don't pop anything if there are fewer than k items on this. This is a method of the ArrayBoundedStack class. DO NOT USE ANY OTHER METHODS OF THE ARRAYBOUNDEDSTACK CLASS.

4. Now examine the ArrayList methods in the above table, a) Which method retrieves elements from the ArrayList? b) Which method replaces the value of an element that already exists in the ArrayList? c) Which two methods initializes the value of an element? d) How do the two methods in (c) differ? Which method(s) would be appropriate in the above Java program (after we convert it to work with ArrayLists)?
