Question: Create a class called Date that includes three instance variables — a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Write a test application named DateTest that demonstrates class Date’s capabilities.
To run the application save both files with the same name as the class (because it is a public class) and with the .java file extension (in this case Date.java and DateTest.java). Then compile both classes and run DateTest. Date will not run because it does not have a main method.
To compile both classes at the same time using the command prompt, use the command
javac Date.java
javac DateTest.java
To run DateTest, use the command
java DateTest
