before you move to the API i guess you need to really get a hold on what an array is, if i may put it in any way an array is just a contiguous memory for similar data types and almost all programming languages support array in java you have to declear an array using the SYNTAX;
datatype  objectname;
where datatype may be any of the primitve data types or an object,
int  x;
String  name;
the next thing is for you to initilize the size of the array after which these is done with the syntax
objectname= new [integer_value_of size];
x= new int;
name= new String ;
you can now assing a value to each index in the array
NOTE :-the index goes from 0 to n-1, n which is the size of the array itself can not be used
if you don't understand the question, don't try to answer. Array != ArrayList as you would have known had you read the documentation (but then, you tell people they shouldn't read the documentation and you clearly have followed your own advise...).
