Question

Amend the Date.java file on p. 77 (also available on the lab drive) so that the Date class: a. Has a month field that is a String instead of an int. b. Has a third constructor that will take in a String parameter (only.) This constructor will parse the String into the month, day, and year fields. The String is provided in the following format: “Month Day, Year”. If the tokenizing and/or parsing generates an exception, the date defaults to January 1, 2020. C. Add accessor methods for each of the three fields of the class, prefixing each with get - e.g.getMonth(), etc. d. Add mutator methods for each of the fields, prefixing each with set - e.g. setMonth(), etc. e. Ensure that all other methods of Date work correctly. You can utilize any classes from the Java API as you see fit. Remember you can reference the Javadocs on the Q: drive. You can work with one other student on this lab if you wish. Upload your zipped.java file to me on Canvas by the start of class. Make sure your name(s), the course number, the lab number, and my name are in a comment block at the beginning of your source file. Rename the Date class (and your source file) accordingly: L17_231XXxx.java, where XXxx represents your first initial and first 3 letters of your last name.

Answer 1

class Date {

private int day, year;

private String month;

public Date() {

month = "January";

day = 1;

year = 2010;

}

public Date(int day, int year, String month) {

this.day = day;

this.year = year;

this.month = month;

}

public Date(String str) {

try {

String[] vals = str.split(" ");

month = vals[0];

String[] dy = vals[1].split(", ");

day = Integer.parseInt(dy[0]);

year = Integer.parseInt(dy[1]);

} catch (Exception e) {

month = "January";

day = 1;

year = 2010;

}

}

public int getDay() {

return day;

}

public void setDay(int day) {

this.day = day;

}

public int getYear() {

return year;

}

public void setYear(int year) {

this.year = year;

}

public String getMonth() {

return month;

}

public void setMonth(String month) {

this.month = month;

}

}
