Why? Have you been
told that you must? If not, don't start putting constraints on yourself before you even start.
and may be or should I try a catch block?
Lesson 2: Don't guess.
try...catch blocks are used for a very specific reason; so before you start coding, read up on WHY you might need one.
The number or numbers that were picked least frequently.
The average number of times that all of the numbers were picked. For example, the average might have been 210 times.
The number or numbers that were picked the average number of times.
The number or numbers that were picked most frequently
Lesson 3:
StopCoding (←click) - or rather, in your case, don't
start coding until you
know what you need to do.
One thing I can tell you is that, in general, the more methods your class has, the better it will be. You've been given 4 tasks to complete, so think about writing 4 methods (at the very least) to do them.
And before you write one line of code for them: THINK.
Take your first task: "[Print out] the number or numbers that were picked least frequently."
What
exactly do you need to do to find out the "least frequent number or numbers"? A good tip is to write out a description as though you were describing it to a child who has no knowledge of
Java.
Also: if you want "number
s", how many do you want? The bottom 3...or 5...or 10? You need to be
precise.
And do that for all 4 tasks
before you write a line of code.
