Step by step
Solved in 2 steps
- Using java, write an easier version of a linked list with only a couple of the normal linked list functions and the ability to generate and utilize a list of ints. The data type of the connection to the following node can be just Node, and the data element can be just an int. You will need a reference like (Java) or either a reference to the first node, as well as one to the last node. (Answer the following questions) 1) Create a method or function that accepts an integer, constructs a node with that integer as its data value, and then includes the node to the end of the list. If the new node is the first one, this function will also need to update the reference to the first node. This function will need to update the reference to the final node. Consider how to insert the new node following the previous last node, and keep in mind that the next reference for the list's last node should be null. 2) Create a different method or function that iteratively explores the list, printing…*in java* A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309 Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the specific contact name.public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize) Hint: Use two arrays: One for the string names, and the other for the string phone numbers.…Writing a program that helps to enter patients information:● Write a class patientInfo which contains the following data and methods:• Data:PatientName (String).PatientID (int).• Methods:Getter and Setter for each data item.toString method.● Display this menu:1:Merging two Single Linked List structure type2:Merging two Stacks data structure type3:Merging two Queses data structure type4:Merging Single Linked List with Stack to Linked List5:Merging Single Linked List with Queue to Linked List6:Merging Singly Linked List with Stack only Patient’s name that start with S to Queue● Ask the user to choose the data structure type from a given list to be merged.If you choose any of the above options:1.You must request [the size of data structures and patient information] from the user.2. Print the data structure before the merge.3. Print data structure after the merge.
- Develop a class named PieChart that extends Canvas for displaying a pie chart using the following constructor:PieChart(parent, data, width = 400, height = 300) Where data is a list, each element in the list is a nested list that consists of a value, a title for the value, and a color for the wedge in the pie chart. For example, for data = [[40, "CS", "red"], [30, "IS", "blue"], [50, "IT", "yellow"]], the pie chart is as shown in the left part of Figure 12.29.For data = [[140, "Freshman", "red"], [130, "Sophomore","blue"], [150, "Junior", "yellow"], [80, "Senior","green"]], the pie chart is as shown in the right part of Figure 12.29. Write atest program that displays two pie charts, as shown in Figure 12.29.Write a Python Code for the given constructor and conditions: Given Constructor: def __init__ (self, a) Pre-condition: Array cannot be empty. Post-condition: This is the default constructor of MyList class. This constructor creates a list from an array.Create a template class for a dynamic 1D array. You can model your class off of our Stringclass or the dynamic list class. Changes from Stringclass: You won't need an end-of-string element in the array. The element type is now templated. Translation will no longer be necessary. operators - and -= 'might' now make sense (erase element(s)?). ... Show how useful your template array class is by creating arrays of short integers doubles Stringclass objects (static) Pointclass objects pointers to Pointclass objects (each allocated on the heap) — all in one test application. Make sure your test application is a good/thorough test of your class. (Your test application might utilize the applyand accumulatefunctions from lecture to facilitate testing. Also note how a typical template test application is structured — using templates to ease development.
- Q# In Java, if you see a class name followed by “<T>”, as in List<T>, what does this mean?Group of answer choices 1.It is what is called a lambda-function. 2.It’s for making collections of objects of many types at the same time. For example, if I make List<T> myList = new List<T> I can put a String as one item, an int as another, and a Random as a third item. 3.You must specify an object type in place of the T; eg. List<Shape> will make a list of Shape objects. 4. It means that the object is of type Time.Question 3. ArraysWrite a Java program that has a method called collapse() which accepts an array of integers as a parameterand returns a new array containing the result of replacing each pair of integers with the sum of thatpair. For example, if an array called list stores the values [ 7, 2, 8, 9, 4, 13, 7, 1, 9, 10 ], then the call ofcollapse(list) should return a new array containing [ 9, 17, 17, 8, 19 ]. The first pair from the originallist is collapsed into 9 (7 1 2), the second pair is collapsed into 17 (8 1 9), and so on. If the list storesan odd number of elements, the final element is not collapsed. For example, if the list had been [ 1, 2,3, 4, 5 ], then the call would return [ 3, 7, 5 ]. The collapse() method should not change the array that ispassed as a parameter.Write a class TouristSpot that has the data members; name of tourist spot, state in which it lies. Create an array list of n places and write a function that takes array list as an argument to identify a state that has more than one tourist spot. Java Program
