I Need help writing the LetterCounter class.

/* * This class counts the occurrences of a letter in lines of English text. * Users may add a letter of their choice to be counted. Users specify if the * letter is case-sensitive. * For example, if the letter is 'Y' and the use specifies case sensitive, the lowercase * y in this line: "You are happy." would not be counted but the uppercase Y would be counted. * If the user entered the letter 'Y' and specified case-insensitive, both of the letters 'Y' and 'y' * would be counted. * Initially, the user letter is intialized to the default value for the primitive data type char. * That value is given by the static value Character.MIN_VALUE. * The current line and letter counts are reset to 0 when the user sets a new letter to be counted. */ public class LetterCounter { /* Member variables declared in this section. */

private String word; private boolean caseSensitive; private int lines;

/* Constructor, where all variables are initialized to default values. */ public LetterCounter(){ word = ""; caseSensitive = false; lines = 0; } /* This method counts the occurences of a user-specified character according * to the current case sensitivity set for that letter. Note that this method * will use the default settings if a user has not set a specific letter and * case sensitivity. * This method also updates the number of lines that have been processed. * Note that this count is not incremented if the line passed in has zero length. */ public void processLine(String line) { } /* This method allows a user to set an arbitrary letter (or character) to be counted. * The case sesitivity criterion is also set. * The user's character is passed in as a String, which is converted * to a single char data type. * The letter and line counts are reset to their default values. */ public void setUserLetter(String userCharStr, boolean caseSensitive) { }
