    Programming Fundamentals III – Java Data Structures COSC 2436 Lab #2 – Bag Implementations That Use Arrays Problem: Complete Programming Project 2, page 92. This will require that you use the ‘SetInterface’ of Chapter 1 instead of the ‘BagInterface’ of Chapter 2. You will add the methods of the interface to the existing class. Then, develop a test application that will verify the functionality of the solution. You may wish to look at the example test applications. As always, be sure to test ALL methods of the class and interface. Requirements: You will submit the lab following the normal lab procedures. Make sure to label your lab folder as follows: 2YourLastName To Be Done: - Open Resizable ArrayBag and rename as ArraySet.java - Global replace of ‘Bag’ with ‘Set’ - Re-write ‘add’ methods to prevent the addition of duplicate entries, using either the ‘contains’ method or ‘getIndexOf’ - We can remove ‘getFrequencyOf’ method. - Update the test class – replace the ‘testGetFrequencyOf’ method and add a method to verify that duplicates can’t be added *PDF of the texbook "Data Structures and Abstractions with Java 3rd edition" available upon request

    Lab #2 – Bag Implementations That Truth Arrays

    Problem:

    Entire Programming Project 2, page 92.

    This conciliate claim that you truth the ‘SetInterface’ of Chapter 1 instead of the ‘BagInterface’ of Chapter 2. You conciliate infer the modes of the interface to the existing dispose. Then, eliminate a ordeal application that conciliate authenticate the functionality of the breach. You may hope to face at the pattern ordeal applications.

    As frequently, be firm to ordeal ALL modes of the dispose and interface.

    Requirements: You conciliate present the lab coercionthcoming the usual lab procedures. Make firm to label your lab folder as follows:

    2YourLastName

    To Be Done:

    – Open Resizable ArrayBag and rename as ArraySet.java

    – Global rearrange of ‘Bag’ with ‘Set’

    – Re-write ‘add’ modes to bar the inferition of likeness entries, using either the ‘contains’ mode or ‘getIndexOf’

    – We can oust ‘getFrequencyOf’ mode.

    – Update the ordeal dispose – rearrange the ‘testGetFrequencyOf’ mode and infer a mode to authenticate that likenesss can’t be infered

    Solution:

    Since no implementation was granted by, future a absence invent coercion ArraySet.java is captured into motive concurrently with the changes instructed. (Assumptions were captured acceptably) :

    Please experience entire implementation of the ‘ArraySet.java’ with the explication as comments:

    import java.util.ArrayList;
    import java.util.List;

    public dispose ArrayEstablished {

    /*
    * Since it is instructed to truth ‘contains’ OR ‘getIndexOf’
    * so we are using java.util.List coercion implementing ‘Set’
    */
    private List<String> groundsEstablished ;

    /*
    * Infer mode implementation using
    * ‘contains’ mode
    * if likeness component detected then retaliate -1
    * else infer component and retaliate 0;
    */
    public int infer(String grounds){
    if(this.dataEstablished == ineffectual){
    dataEstablished = novel ArrayList<String>();
    }
    if(dataSet.contains(data)){
    retaliate -1;
    }else{
    dataSet.add(data);
    retaliate 0;
    }
    }

    /*
    * Ordeal mode coercion infer()
    */
    public destitute ordealAdd(String ordealData){
    if( this.add(testData) == -1 ){
    System.out.println(“Likeness component detected : ” + ordealData);
    }
    }

    /*
    * Stereotypeing established
    */
    public destitute stereotype(){
    if(this.dataEstablished != ineffectual){
    System.out.println(“Printing established components: “);
    dataSet.forEach(e -> System.out.print(e + ” “));
    }
    System.out.println(); // Stereotypeing a unmitigated line
    }

    public static destitute ocean(String[] args) {

    //Creating ArrayEstablished object
    ArrayEstablished established = novel ArraySet();
    set.add(“1”);
    set.add(“2”);
    set.add(“3”);
    set.add(“4”);
    set.add(“5”);
    set.add(“6”);

    set.print();

    System.out.println();

    //Running ordeal mode
    set.testAdd(“2”);
    set.print();

    System.out.println()
    ;
    set.testAdd(“99”);
    set.print();
    }

    }
