Me with java: this is my assignment. i need to write a program with a main method and methods. use a scanner to get the string from the user. i am lost. don't use the following in the program: import java. io. bufferedreader; import java. io. ioexception; import java. io. inputstreamreader;

Here you go. I did not see the need to create a separate class to return one string character to an array index, since I only have to make that conversion once, where I increment the array value (the part with  [c-'a']).

The user can terminate the program by pressing enter, ie., enter an empty string.

import java.util.Scanner;

public class Analyzer  

{    

  public static void Analyze(String line)  

  {  

       int[] histogram = new int[26];

       for(int i=0; i<line.length(); i++) {

           char c = Character.toLowerCase(line.charAt(i));

           if ((c >='a' && c <= 'z')) {

               histogram[c-'a']++;

           }

       }

       for(int i=0; i<26; i++) {

           if (histogram[i] > 0) {

              System.out.format("%c: %d times.\n", 'a'+i, histogram[i]);  

           }            

       }

  }  

  public static void main(String[] args)  

  {      

       String line = "";

       Scanner scan = new Scanner(System.in);

       do {

           System.out.print("Enter a string: ");

           line = scan.nextLine();

           if (line.length()>0) {

               Analyze(line);

           }

       } while (line.length() > 0);

  }

}

answer; i do believe that the correct answer is : a deadly factory fire;
