Evaluate the JAVA code snippet below, then motivate why this is representative of good programming practices or not.
public class pattern{ public static void main(string[] args){ int rows = 5; for(int i = 1; i <= rows; ++i){ for(int j=1;j<=I;++j){ system.out.print(“*”); } System.out.println(); } }

Create a 2-dimensional array that stores student marks for the programming exam, assignment & test.
- Exam count 50%, test & assignment count 25% towards a pass mark.
- Request the user to enter the name, exam, assignment, and test mark for each student.
- Calculate the pass rate for the module.
- Passed student: Mark is greater or equal to 50
- Pass rate = (total number of passed students * 100)/Number of students.
- Calculate the final mark for each student
- Calculate the lowest final mark and the highest final mark

Class Clock
A Clock object is used to simulate time and the passing of time.
A Clock can be examined and the time advanced. (It does not advance time on its own, hence “simulate”.)
Instance variables
Time currentTime;
Constructors
Clock(Time time)
// Create a Clock set to the given time.
Methods
public void advance(Duration duration)
// Advance the clock time by the given duration.
public Time examine()
// Obtain the current time (as recorded by this clock).
A Clock is mutable in that it stores a time
