Question

write a program which include a class containing an array of words
(strings).The program will search the array for a specific word. if it finds the word:it will return a true value.if the array does not contain the word. it will return a false value.

enhancements:

make the array off words dynamic, so that the use is prompter to enter the list of words.

make the word searcher for dynamic, so that a different word can be searched for each run

produce a total count of the number of time the word is found, so that if the word is found more than once in the array, atotal count is porduced

All above are the question:Below are what i typed, can you teach me how to fix it. there are no error but i cannot finish some questions above

import java.util.Scanner;
import javax.swing.JOptionPane;
public class Davidhw1
{
public static void main(String[] args)
{String name;
   // Description of the program
   JOptionPane.showMessageDialog( null, "\n This program calls a method to search an array for the word ");
       //create an array
   String [] list= new String[10];
   Scanner scan= new Scanner(System.in);
for (int x=0;x<10;x++)//create a list
{
   System.out.print("Enter name:");name=scan.nextLine();
   list[x]=name;
}
int t=0;
for(int i=0;i<list.length;i++)
{System.out.print("Enter the word you want to search:");
String x=scan.nextLine();//enter the word you want to search
if(list[i].contains("x"))
{
   t=t+1;
   System.out.println("The word is in the array");
}
}
if (t > 0)
{
System.out.print( "The word exists in the Array");

}
else{
   //not found
   System.out.println("The word is not in the array");

/*Modified java program that prompts user to enter
number of string to enter and then prompts the strings
and then prompt for the search string and then prints
the count of the string in the list */
//Davidhw1.java

import javax.swing.JOptionPane;

   /**

   public static int searchName(String[] list, String x) {      

       //set count=0
       int count=0;

       {          
           if(list[i].contains(x))
           {
               //increment count by 1
               count=count+1;      
           }
       }
       //return count
       return count;
   }//end of method searchName

}//end of the class

Sample output:

Enter number of words to read from keyword
3
Enter name:apple
Enter name:apple
Enter name:orange
Enter the word you want to search:apple
The word exists in the Array 2 times
