How to find the length of an array list? [duplicate]
I don't know how to find the length of an array list. I think you might need to use blank.length();
but I'm not sure.
I made an array list
ArrayList<String> myList = new ArrayList<String>();
but how do I write code to print out the size of myList?
The size member function.
myList.size();
http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html
System.out.println(myList.size());
Since no elements are in the list
output => 0
myList.add("newString"); // use myList.add() to insert elements to the arraylist
System.out.println(myList.size());
Since one element is added to the list
output => 1
