In the United States, we commonly express dates by listing the month, then the day then

the year, all separated by slash marks. In Europe, however, dates are commonly

expressed by listing the day first, then the month, then the year, all separated by periods.

Write a Java application program $($name the file as DateChange.java$)$ that will get a line

of text containing a date in US form from the user, and then change this date to European

form.

Begin by asking the user to enter a date in the form of month$/$day$/$year$.$ Store this date in

a String variable.

Next, use the appropriate String methods to swap the month and day parts of the date, and

replace the slash marks with periods. Print the revised String to the screen.

For this question, you are NOT allowed to use the $$split$$ method in the String class.

Please note that users are allowed to input the year in two digits or four digits, and

input the month and day in one digit or two digits. Your program should be able to

handle all possible cases.

The following is an example of what you might see on the screen when your program

runs. The exact output depends on the values that the user types in while the program

runs. The user's values are shown below in italics:

Enter a date in the form mon$/$day$/$year:

$06/17/2008$

Your date in European form is:

$17\mathrm{.}06\mathrm{.}2008$

Here is another example run:

Enter a date in the form mon$/$day$/$year:

$5/3/09$

Your date in European form is:

$3\mathrm{.}5\mathrm{.}09$
