Question

The Name Game Lab objective To read, search and sort, an Array of strings Assignment Download the following 2 files from Blackboard. Make sure you save both of the files in the same folder. period2.ixt or period3.txt depending on which class you are in. Name Game java The text file contains a list of all the students in your class (first name only). The java program will read the list of names from the text file and store each name in an array. Your assignment is to write the body of the 4 methods defined in the NamoG java file. Below is a description of the task of each method. ame print List Public static void printlist (Stringt) array) This method should print a list of all the names in the array numbered For example 2 Sally 3 Harry shuffle public static void shuffle (Stringti array) This method should mix up all the elenents in the array one way to shuttle a list is to pick 2 random elements in your list and swap them Repeat thia proceno 20 time or search public static int search (string 1 array, string key This method the array the You should perform a linear or tial search on the starting from the element position to the end of the array. If you find the "key" in the array, then you should return the position of the key. If you do not find the "key" in the array then you should return a value of (negative one averageLength public static double averageLength string (I array This method should return the average length of the names in the array.

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.Random;
import java.util.Scanner;

public class NameGame {

   public static void main(String[] args) throws FileNotFoundException { // throwing exceptions
       Scanner s = new Scanner(new FileInputStream("D:\period2.txt")); // Scanner for reading from file
       StringBuffer sb = new StringBuffer(); // Creating StringBuffer for Storing Strings
       while(s.hasNextLine()) {
           sb.append(s.nextLine()+" "); // Appending to Buffer
       }
      
       String arrayNames[] = sb.toString().split(" "); // Splitting with and storing into array
       System.out.println("************NAMES IN ARRAY**************");
       printList(arrayNames);
       System.out.println("************SHUFFLED STRINGS***********");
       shuffleList(arrayNames);
       System.out.println("***********SEARCH STRING*********");
       System.out.println("Enter the key:");
       String key = new Scanner(System.in).next();
       searchList(arrayNames,key);
       System.out.println("************AVERAGE LENGTH************");
       averageLength(arrayNames);
   }

   //Method for average String length of arrays
   private static void averageLength(String[] arrayNames) {
      
       int sum=0;
       for(int i=0;i<arrayNames.length;i++) {
           sum = sum+ arrayNames[i].length();
       }
       int average = sum/arrayNames.length;
      
       System.out.println("The average Length is:"+average);
   }

   //Method for searching the String in the array
   private static void searchList(String[] arrayNames, String key) {
       int pos = -1;
       for(int i=0;i<arrayNames.length;i++) {
           if(key.equals(arrayNames[i])){
               pos = i;
           }
       }
       if(pos>-1)
           System.out.println(key+" found at position"+" "+pos);
   }

   //Method for shuffling Strings in the array
   private static void shuffleList(String[] arrayNames) {
       Random r = new Random(); // Creating Random object for random positions
       for(int j=0;j<arrayNames.length;j++) {
           int p1 = r.nextInt(26); // One random position
           int p2 = r.nextInt(26); //Second Random Position
           String temp; // swapping p1 and p2 using temp
           temp = arrayNames[p1];
           arrayNames[p1] = arrayNames[p2];
           arrayNames[p2] = temp;
       }
      
       System.out.println("String after Shuffling:");
       //Printing after shuffling
       for(int k=0;k<arrayNames.length;k++) {
           System.out.println(arrayNames[k]);
       }
   }

   //Method for print Strings in the array
   private static void printList(String[] arrayNames) {
      
       System.out.println("The names in the array are:");
       for(int i=0;i<arrayNames.length;i++) {
           System.out.println(arrayNames[i]);
       }
      
   }
