public class USconstitution   
{

     int x = 0;
     int keyword1 = 0;
     Scanner keyboard = new Scanner(System.in);
     System.out.println("Enter a word from the keyboard");
     String input = keyboard.next();
     while(inFile.hasNext())
     {
        String word = inFile.next();
        x++;
        if(input.equalsIgnoreCase(word))
           keyword1++;
     }
     //System.out.println("\n" + x);
     System.out.println("The constitution has " + x + " words");
     System.out.println("The first keyword shows up " + keyword1 + " times in the  

     constitution");
