Need to create JUnit test file for this one.

import java.util.Scanner; public class Homeworkl{public static void main(String[] args) {//Let the user know what this program is for. JOptionPane.showMessageDialog(null, "This program calls a method to search an array for the specified word");//Array Declaration int t = 0;//Instantiate the Array//Make the array of words dynamic System.out.print("How many words would you like to list? (Please enter positive number): "); Scanner sc = new Scanner (System.in); int numberOfWords = sc.nextlnt(); String[] wordList = new String[numberOfWords]; System.out.println("");//Prompt the user to input the list of the words System.out.println("*Enter the list of words"); for(int i = 0; i

Explanation / Answer

Hi there ,

I have made some changes on your code so that it could run without any problem.I have removed the JOptionPane from the for loop and I have placed it outside the loop and I have created a method and the implemntation I have moved it from main() to this newly created method and after that I have created a JUnit Test file named Homework1Test.Please have a look.

Homework1.java:

package com.chegg.programs;

import java.util.Scanner;

import javax.swing.JOptionPane;

public class Homework1 {
  
   public static void main(String[] args) {
      
       Homework1 homework1 = new Homework1();
       homework1.show();
   }

   public void show() {

       JOptionPane.showMessageDialog(null, "This program calls a method to search an array for a specified word");

       // Array declaration
       int t = 0;

       // make the array of the words dynamic
       System.out.println("how many words would you like to list?(Please enter positive number):");
       Scanner sc = new Scanner(System.in);
       int numberOfWords = sc.nextInt();
       String[] wordList = new String[numberOfWords];
       System.out.println("");

       // Prompt the user to input the list of the words

       System.out.println("Enter the list of the words");
       for (int i = 0; i < numberOfWords; i++) {

           System.out.println("Words" + (i + 1) + ".");

           wordList[i] = sc.next();

       }
       // make the word searched for dynamic,so that a different word can be
       // searched for each run
       System.out.println("");
       System.out.println("Enter the word searching for:");
       String userInput = sc.next();

       // printout the result with count of the number of times the word is
       // found.
       for (int i = 0; i < wordList.length; i++) {

           if (wordList[i].contains(userInput)) {
               t = t + 1;
               JOptionPane.showMessageDialog(null, "Array value is True:" + wordList[i]);
break;
           }
          
       }
       if (t > 0) {
           JOptionPane.showMessageDialog(null, userInput + "exists in the Array " + t + "times.");
       } else {
           JOptionPane.showMessageDialog(null, userInput + "does not exist in the Array");
       }

   }

}

Homework1Test.java(Your JUnit test file):

package com.chegg.programs;

import static org.junit.Assert.*;

import org.junit.Test;

public class Homework1Test {
  
  
   @Test
   public void testMain() {
       Homework1 homework1 = new Homework1();
       homework1.show();
   }

}

Hope this helps you.
