I understand that when you iterate a regular array element it is like so:
int[] counter = new int[10];
for loop{
counter[i] = 0;
}
when button clicked{
counter[0]++; //For example
counter[6]++;
}
However I'm not understanding how to iterate through elements of an arraylist. If someone could help me understand I'll be appreciative. Thanks!
The easiest way would be to use a for each loop
for(int elem : yourArrayList){
elem;//do whatever with the element
}
for (int i = 0; i < arrayList.size(); i++) {
}
Or
Iterator<Object> it = arrayList.iterator();
while(it.hasNext())
{
Object obj = it.next();
//Do something with obj
}
Iterating over an array list is really simple.
You can use either the good old for loop or can use the enhanced for loop
Good Old for loop
int len=arrayList.size();
for(int i = o ; i < len ; i++){
int a =arrayList.get(i);
}
Enhanced for loop
for(int a : arrayList){
//you can use the variable a as you wish.
}
