How to print all the Mondays in given month and year in Java?



Problem Description :


Write a program in Java that prints all the Mondays in given month and year. For example in Jan
2017 there are 5 Mondays and dates are 02/01/2017, 09/01/2017, 16/01/2017, 23/01/2017, 30/01/2017.

Concept :


If you have read our previous date and time problems then believe me this problem would be piece of cake for you. With the help of Calendar class constants MONTH, YEARDAY_OF_MONTH and DAY_OF_WEEK we can easily solve this problem.


Algorithm :


  1. Find number of days in given month.
  2. Set given month and year in Calendar.
  3. Iterate the loop from 1 to number of days ( Step 1 ) times.
  4. Set the day of month as current index in Calendar.
  5. Check the day, if it is Monday print it else go to Step 3.
