I have tried to create a java code which stimulates the game of cricket.
I know many of you may not know this game. Basically, what I want to do is randomly generate numbers (weighted probability – not completely random) and add them to a static int called total.
I want to display the Total using the JLabel.

But for some reason, the total doesnt update. It says 0-0.
It should give other results like 140 or 200 because i have coded it to add randomly generated numbers to the total approx. 120 times.

I think I may be missing something.

I think it is something apparent which my blank brain cannot read atm.
Can somebody plz help me with this?
Thanks

Make sure to check that greater than and lesser than signs are at the right place.

In this program the if and else if statements never get executed because the conditions that I have put there are never true!

Thats why the total score is not updated.
