**** classic
**** stream
**** separate function
* generics overview
* basic reflection usage (TestNG listeners)

h5. Practice

# *Multiplication Matrix*
#* print multiplication matrix, separate header and leftmost column with some symbol, like \|
#** just hardcode matrix size in code
#** for-loop
#** streams (replace for-loop, int range etc.)
#** String.format()
#** mind how spaces are placed between numbers, try different matrix sizes, 10*10, 10*20, 100*100
Example output
{noformat}
1 | 2  3  4
--|-------
2 | 4  6  8
3 | 6  9 12
{noformat}
# *Happy Tickets*
#* happy tickets (8 digits) - ticket is happy if sum of left 4 digits of the number equal to sum of right 4 digits of that same number
#** projects
#*** classic with jars
#*** Maven with dependencies
#** use Java native methods to get random number
#** use Apache Commons Lang library
#** count % of happy tickets to all generated
#** timings
#*** millis vs nano (1 and 2 seconds are the same if System.currentTimeMillis() is used, try measure with nanoTime)
#*** given 10 seconds, how many of happy tickets could be generated
#**** generate list at first and then find happy tickets in it
#***** concerns
#***** memory to hold whole list (count how many MBs it takes)
#***** use smaller Xmx and run via cmd
#***** generate one random number and check for happiness at runtime
#**** given amount of ticket (1_000_000) to be generated, how much time will it take
#***** parameterize numbers to be generated, run via cmd, use system property
#***** find (has 11 in the middle), 121156
#***** predicates (combined, 3rd digit is 1 and 4th digit is 1)
#***** sort (by two middle digits, comparator)
#***** generate via stream, limit 100_000
#****** classic for loop
#****** streams
#* OOP
#** make a wrapper to generated number, interface MyRandomNumber
#** create isHappy() method to check if number is happy
#*** classic
#*** stream
#** create getType() method to return ODD/EVEN depending on a number
#** create factory class that returns OddRandomNumber/EvenRandomNumber wrapper implementation depending on a type (implement MyRandomNumber)
#** put all numbers in List<MyRandomNumber>
#** group list by type into map
#*** classic
#*** stream
#** generator
#*** use system property to pass generator (java, apache)
#*** create generator factory
#*** create two implementation Java, Apache that use appropriate algorithm to generate number
#*** use generator in place where random number is generated (think of a way to pass in generator where needed)
