how to write a program for " world cup " in java

hi guys ,,,

im new in this forum ,,, i came here cause i needed help with something

i was trying to improve my java ,, so i decided to write a program for the world cup " calculates the points and goals .... etc"

but i had a problem with ranking the teams ,, i used linked lists to list the teams ,,, so this is the method i wrote for sorting teams ,, plz if you could help ill be thankful

public void sort(){
Team T1=new Team();
Team T2=new Team();
Team T3=new Team();
Team T4=new Team();
int max1=0;
int max2=0;
int max3=0;
int max4=0;
points();// calculates the points depending on how many time the team won or drew
Node current=first;
while(current!=null){
int P=current.data.P;// data.P means the teams points ofcourse data is of type team
if(P>=max1){
current.data.rank=1;
T1=current.data;
max1=P;
}
if(P>=max2&&P<max1){
current.data.rank=2;
T2=current.data;
max2=P;
}
if(P>=max3&&P<max2){
current.data.rank=3;
T3=current.data;
max3=P;
}
if(P>=max4&&P<max3){
current.data.rank=4;
T4=current.data;
max4=P;
}
if(T1.P>current.data.P){
T4=T3;
T3=T2;
T2=T1;
T1=current.data;
max4=max3;max3=max2;max2=max1;max1=current.data.P;
}
if(T2.P>current.data.P&&T2.P<max1){
T4=T3;
T3=T2;
T2=current.data;
max4=max3;max3=max2;max2=current.data.P;
}
if(T3.P>current.data.P&&T2.P<max2){
T4=T3;
T3=current.data;
max4=max3;max3=current.data.P;
}
if(T4.P>current.data.P&&T4.P<max3){
T4=current.data;
max4=current.data.P;
}
current=current.next;
}// end while
this.Empty();// this method empties the linked list
InsertAtFront(T4);
InsertAtFront(T3);
InsertAtFront(T2);
InsertAtFront(T1);
}// end method

thanks in advance

Can you describe the problem you are having?

well basically i couldnt rank the teams like " first -second -third -fourth" i have to do that depending on the points each team has ,, i tried to do that and empty the list and then insert the teams again ranked and in order

I don't see any lists in your code. If your objects were in a list then there are sort methods that would do the sorting for you.

i didnt put the whole code here ,, i just put the sorting method

how can i use the methods youre talking about ?

There are sort() methods for several classes. Go to the API doc for Java, at the top of the page is an "Index" link, click it, then click on the "S" link, then search for "sort(".
You'll find several classes that have that method.
Then start reading the doc for those classes.

where is that ?

I downloaded my version from the Sun site.
If you don't know about the Java API doc ???
What can I say. You MUST know how to use the API doc to be able to do any java programming.

Do you mean: Do I have to write the code?
Yes.

yeah ,, thats what i mean

OK, We'll leave you to it.

so you cant help me ?

Of course we could help you, but you didn't ask anything specific. Try it yourself, post your best attempt and come back with specific questions.

i did try ,, and i posted my best attempt above ,, and the one question im asking is " how can i sort the teams depending on the points they have "

And you got the advice to have have a look at the various sort(......) methods that are available in the API. What have you found out about them? Where are you stuck?

they are not built-in methods ,, so i have to write their code ,, which is my problem in the first place

Ahem, they are in the API docs, so how do they get there if you have to write them? Norm said that you will need to write code to use them.

what code do i need to write ?
