hey i need some help with my assignment am a seriose beginner

i need to create a program using arrays that prompts the user to write
a sentence and then prints outs the word and the number of times its appearing..i don't know where to begin

please help :(

Break the problem up into separate steps and do one step at a time.
For example: prompt for a sentence and read in the sentence and print it out.
See the Scanner class for a way to read in a sentence. Many code samples on this forum if you use Search.

  1. import java.util.Scanner;
  2. public class WordCount
  3. {
  4. public static void main (String [] args)
  5. {
  6. Scaner input = new Scanner (System.in);
  7. int numWords=0;
  8. System.out.print("Enter a sentence: ");
  9. String userString = input.nextLine();
  10. userString = userString.substring(0, userString.length()-1);
  11. for (int i = 0; i < userString.length(); i++)

  12. }
  13. }
  14. }

Can you explain what that code is supposed to do?
That's normally done by adding comments to the code.

What is the next step in your assignment?

public class LetterCount
  public static void main (String [] args)
  int freq = 0; // frequency of charactersdeclared and initialised to zero

  String lineTwo ; //string called lineTwo initialised.

  System.out.println("Enter a string of text;\n"); // prompt user for the a string of text.
  lineTwo = input.nextLine();	                   // read text from user.

  System.out.println ("Enter letter");             // prompt user to enter a letter
                                                   // in which they would like to find                    
                                                   // out  how many times its appearing.
  String letter = input.nextLine();                // get line of text from user

  for (int i = 0; i<lineTwo.length(); i++)    //iterate through the line of text up                                                                       the length of the text entered.
    if (lineTwo.charAt(i) == letter.charAt(0))     // compare the character at i 
                                                   // from the first line and character that the user inputs
      freq++; // increment the frquency by 1 if the comparison in the of statement is equal.

    if ((lineTwo.length()-1) == i) // compare
       System.out.printf("%s \t %d", letter, freq ); // print the letter and how many times its appearing.
       System.out.printf("\n\n"); // print two lines.

i managed to write the code buh i used string.
