}java how to iterate through a arraylist
// Using Classic For Loop
for (int i=0; i<myArrayList.size(); i++) {
System.out.println(myArrayList.get(i));
}
/*****************************************************/
//Advanced For Loop - ArrayList<String>
for(String str : myArrayList) {
System.out.println(str);
}
/*****************************************************/
//Using Iterator
Iterator arrayListIterator = myArrayList.iterator();
while (arrayListIterator.hasNext()) {
System.out.println(arrayListIterator.next());
}
/*****************************************************/
//ForEach - java 8 - ArrayList<String>
myArrayList.forEach( str -> System.out.println(str));iterate through an arraylist java
// will iterate through each index of the array list
// using the size of the array list as the max.
// (the last index is the size of the array list - 1)
for (int i = 0; i < myArrayList.size(); i++) {
System.out.println(myArrayList.get(i));
// will print each index as it loops
