LAB: Praising dates Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substring() method to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.
Ex: If the input is:
March 1, 1990
April 2 1995
7/15/20
December 13, 2003
-1
then the output is:
3/1/1990
12/13/2003

Explanation:

The following is the entire modified code, it takes in the date as an input and continues changing the dates to the desired format. If the input format is wrong it says "Wrong Format" and requests another input. If -1 is passed as an input the program terminates.

        import java.util.Scanner;

        class DateParser {

public static int getMonthAsInt(String monthString) {

        int monthInt;

        switch (monthString) {

            case "January" :

                monthInt = 1;

                break;

            case "February":

                monthInt = 2;

                break;

            case "March":

                monthInt = 3;

                break;

                monthInt = 4;

                monthInt = 5;

                    try {

                        if (Character.isDigit(date.charAt(date.length()-8))) {

                            day = date.substring((date.length()-8), date.length()-6);

                            month = date.substring(0, date.length()-9);

                        } else {

                        }

                        if ((year.length() == 4) && (day.length() > 0) && (day.length() <= 2) && (month.length() >= 3)) {

                            System.out.println(getMonthAsInt(month) + "/" + day + "/" + year);

                        } else {

answer; monitor is the correct answer. good luck

answer; i believe that the correct answer is (training);
