Population Clock

+2 Suraj Gautam · January 7, 2016
Hello peeps,
I am new to Java and my teacher has given me project to make Population Clock in Java. I have experience of C language. I have gone through Bucky's Java tutorial. I have idea of object oriented programming language. 
About Project:
I have to make Population Clock in Java which shows the population with respect to time. The population must be changed within a second (Either increase or Decrease). Please give me idea how to start it?
What things I must know to complete this project?

Here are my ideas:
1. You need a timer.  - See javax.swing, or goggle java timer
2. You are going to need a random number for the populationChange. - See the math class.
3. You have to decide whether to increase of decrease. -  I would do something simple like if ((populationChange % 2) == 0)
4. The user interface depends on if you are suppose to use a GUI or not.

These are just my ideas. There are always other ways.

Good Luck

Thank You very much Gary Whitney. If you have any link related to timer then please forward it :)

All I do is Google it e.g. java timer examples.
However, since you asked for a link ...

I find the mkyong site examples are easy to understand.

Contrary to what Gary said, I'd probably stay away from making the population increase then decrease as a set pattern. It's just a little thing, but I'd probably use a random number to determine that too, since it seems to make more sense (in my eyes, at least.) like that.
