Each time kevin re-reads his java book(which happens every month), he learns 10% of whatever material he didn’t know before. he needs to score at least 95% on the comprehensive exam to become a certified java developer. when kevin’s started, he knew nothing about java . write a method that simulates kevin’s learning progress and returns the number of months it will take him to get ready for the exam. write a main method that displays the result (in years and months).

The java main method that can be used to display the number of years and months to get ready for the exam is explained below.

Explanation:

public class GetMonths {

public static void main(String[] args) {

 int noofmonths = 0;

 int noofyears = 0;

 double percentnotknown = 100;

 double percentKnown = 0;

 while (percentKnown<95) {

 percentnotknown *= 0.9;

 percentKnown = 100 - percentnotknown;

 noofmonths++;

 if (noofmonths==12) {

   noofyears++;

   noofmonths = 0;

 } // end if

 } // end while

 System.out.println("After "+noofyears+" years, "+noofmonths+" months,");

 System.out.println("Percentage known = "+percentnotKnown);

} // end main()

} // end class

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
