Exercise 07: Simple Date
Create the Java class called SimpleDate and complete the class with attributes
int day; int month; int year; using the private accessor modifier.
Write:
• get methods for each attribute
• writing set methods for the instance variables such that
? day can only be set to a value between 1 and 31,
? month can only be set to values 1 to 12
? year is a value between 2000 and the current year.
If these conditions are not met by the set method's input parameters,
choose appropriate default value to set the instance variable to instead.
• a method public void setDate (int day, int month, int year)
that sets the instance variables using the set methods you've written.
• use setDate method to write constructor with the method signature
SimpleDate (int day, int month, int year)
Choose some appropriate initial values for the SimpleDate attributes and
use these values to write the default constructor.
Write a toString method returning a string of the form "DD/MM/YYYY".
To construct this string, use String concatenation (+) to form the required
output.
Create a program SimpleDateApplication.java with a main method that tests
the functionality of each SimpleDate method. For example, consider the
following code snippet:
SimpleDate d1 = new SimpleDate();
d1.setDay(22);
d1.setMonth(3);
d1.setYear(2016);
System.out.println(d1);
SimpleDate d2 = new SimpleDate(14,03,2016)
System.out.println(d2);
