Some more multitasking java issues
- by owca
I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/200660/
Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. When I type the values it sometimes catches them and decrease amount of matches but that's not exactly what I was up to :) Logics is : I check the value of current player. If it corresponds to this of the thread currently active I use scanner to catch the amount of matches. Else I wait one second (I know it's kinda harsh solution, but I have no other idea how to do it).
Class Shared keeps the value of current player, and also amount of matches.
By the way, is there any way I can make Player and Shared attributes private instead of public and still make the code work ?
CONSOLE and INPUT-DIALOG is just for choosing way of inserting values.
class PlayerMan extends Player{
static final int CONSOLE=0;
static final int INPUT_DIALOG=1;
private int input;
public PlayerMan(String name, Shared data, int c){
super(name, data);
input = c;
}
@Override
public void run(){
Scanner scanner = new Scanner(System.in);
int n = 0;
System.out.println("Matches on table: "+data.matchesAmount);
System.out.println("which: "+data.which);
System.out.println("number: "+number);
while(data.matchesAmount != 0){
if(number == data.which){
System.out.println("Choose amount of matches (from 1 to 3): ");
n = scanner.nextInt();
if(data.matchesAmount == 1){
System.out.println("There's only 1 match left !");
while(n != 1){
n = scanner.nextInt();
}
}
else{
do{
n = scanner.nextInt();
}
while(n <= 1 && n >= 3);
}
data.matchesAmount = data.matchesAmount - n;
System.out.println(" "+
name+" takes "+n+" matches.");
if(number != 0){
data.which = 0;
}
else{
data.which = 1;
}
}
else{
try {
Thread.sleep(1000);
} catch(InterruptedException exc) {
System.out.println("End of thread.");
return;
}
}
System.out.println("Matches on table: "+data.matchesAmount);
}
if(data.matchesAmount == 0){
System.out.println("Winner is player: "+name);
stop();
}
}
}
