- Use java.util.Map, java.util.Set and given class Parition.java, write a Java method that receives a positive integer and prints all of its partitions. For example, if the input is 5, it prints the following seven lines, each representing one partition of integer 5 Please can you help with the following activity? Use java. util.Map, java. util.Set and given class Parition.java: import java.util.*;public class Partition implements Comparable<Partition> { /*represents a partition for int sum. * Example: * if sum = 14, * frequency can be { * 1:1, 3:1, 5:2} * which means 14 = 5 + 5 + 3 + 1 * */ public int sum; public String rep = ""; public TreeMap<Integer,Integer> frequencies; Partition(){//default constructor, parition for sum = 1 frequencies = new TreeMap<>(); this.sum = 1; frequencies.put(1, 1); } Partition(int sum){ frequencies = new TreeMap<>(); this.sum = sum; } public String toString(){…Use the class MyArrayList to implement the interface MyList listed below using parallel streams and write a test program to test the methods.

Write a MapReduce driver program in Java for the given mapper and reducer classes thatperform a word count on a data set stored in a text file.public class Map extends Mapper<LongWritable,Text,Text,IntWritable> {@Overridepublic void map(LongWritable key, Text value, Context context)throws IOException, InterruptedException {String[] row = value.toString().split("\t");context.write(new Text(row[2]),new IntWritable(1));}}public class Reduce extends Reducer<Text, IntWritable,Text,IntWritable> {@Overridepublic void reduce(Text key, Iterable<IntWritable> values, Context context)throws IOException, InterruptedException {int count = 0;for (IntWritable value:values) {count += value.get();}context.write(key, new IntWritable(count));}}
- Implement a generic priority queue in Java and test it with an abstract Cryptid class and two concrete Cryptid classes, Yeti and Bigfoot. Create a code package called pq and put all the code for this assignment in it. Write the abstract class Cryptid. A Cryptid has a name (a String) and a public abstract void attack() method. Name should be protected. The class implements Comparable<Cryptid>. The compareTo method returns a negative int if the instance Cryptid's name (that is, the name of the Cryptid you called the method on) is earlier in lexicographic order than the name of the other Cryptid (the one passed in as an argument; it returns a positive int if the other Cryptid's name is earlier in lex order, and returns 0 if they are equal (that is, if they have all the same characters.) This part is easy; just have the method call String's compareTo() method on the instance Cryptid's name, with the other Cryptid's name as the argument, and return the result. Extend Cryptid…Write a test client TestBinarySearch.java for use in testing the implementations of min(), max(), floor(), ceiling(), select(), rank(),deleteMin(), deleteMax(), and keys() that are given in the text. Start with the standard indexing client . Add code to take additional command-line arguments, as appropriateCreate a new concreteclass that implements MyMap using open addressing with linear probing.For simplicity, use f(key) = key % size as the hash function, where size isthe hash-table size. Initially, the hash-table size is 6. The table size is doubledwhenever the load factor exceeds the threshold (0.5).
- We wish to build a Hash Table, which is able to deal with collision by using linear and quadratic probing. Please write a public class HashLinQuad as follows: public class HashLinQuad { private int[] table; //hash table private int size; //current number of elements private int capacity //capacity of the hash table private HashLinQuad (int size){ table = new int[size]; } public int addLin (int obj) { … //add obj into table using linear probing } public int addQuad (int obj){ … //add obj into table using quadratic probing } … } 1. Implement the two methods addLin and addQuad that apply linear and quadratic probing, respectively. 2. Test your implemented methods addLin and addQuad . To this end, create the following two objects in class Main : HashLinQuad linHashTable = new HashLinQuad(1249); HashLinQuad quadHashTable = new HashLinQuad(1249); 3. Please insert the same 1000 random integer values (in the same order) into: a. the object `linHashTable` by using the method `addLin` and count…Write a recursive instance method named findBad that takes no parameters and returns a reference to a Link. The result of calling findBad is a reference to the first link that has a value greater than the next link's value. If no such link exists return null. For example, for {5→6→7→3→2} it would return a reference to the third link ("7").C++ Design a HashMap without using any built-in hash table libraries. Implement the MyHashMap class: MyHashMap() initializes the object with an empty map. void put(int key, int value) inserts a (key, value) pair into the HashMap. If the key already exists in the map, update the corresponding value. int get(int key) returns the value to which the specified key is mapped, or -1 if this map contains no mapping for the key. void remove(key) removes the key and its corresponding value if the map contains the mapping for the key. Example 1: Input ["MyHashMap", "put", "put", "get", "get", "put", "get", "remove", "get"] [[], [1, 1], [2, 2], [1], [3], [2, 1], [2], [2], [2]] Output [null, null, null, 1, -1, null, 1, null, -1]
- This question is in Java. We are required to map over some data and incement by 10. import.java.util.stream.Collectors; import.java.util.stream.Stream public class IncrementTheData implements Assignment {public Object solution(ArrayList<Integer> nums) { Stream.of(1,2,3,4,5,6) .map(not sure what would go in here) .collectors(Collectors.toList())return null;}} //So this is as far as I got with this question. The instructions are vague but I think I'm on the right track. Am I?Please implement in Java implement a keyed bag in which the items to be stored are strings (perhaps people’s names) and the keys are numbers (perhaps Social Security or other identification numbers). So, the in- sertion method has this specification: public void insert(String entry, int key);// Precondition: size( ) < CAPACITY, and the // bag does not yet contain any item// with the given key.// Postcondition: A new copy of entry has// been added to the bag, with the given key. When the programmer wants to remove or retrieve an item from a keyed bag, the key of the item must be specified rather than the item itself. The keyed bag should also have a boolean method that can be used to determine whether the bag has an item with a specified key. In a keyed bag, the pro- grammer using the class specifies a particular key when an item is inserted. Here’s an implementation idea: A keyed bag can have two private arrays, one that holds the string data and one that holds the corresponding…Let a and b denote object modules or static libraries in the currentdirectory, and let a → b denote that a depends on b , in the sensethat b defines a symbol that is referenced by a . For each of thefollowing scenarios, show the minimal command line (i.e., one with theleast number of object file and library arguments) that will allow thestatic linker to resolve all symbol references:A. p.o → libx.a → p.oB. p.o → libx.a → liby.a and liby.a → libx.aC. p.o → libx.a → liby.a → libz.a and liby.a → libx.a →libz.a
