Scan all integers on a line into an ArrayList


I would open the file, read the first line and split it.

    BufferedReader br = new
BufferedReader(new FileReader("file.txt"));
      try {
          String[] numbers_= br.readLine().split("
");
          int[] numbers = new
int[numbers_.length]; //I don't remember if this
could be done.
          for(int i = 0; i < numbers.length;
i++) {
             numbers[i] = Integer.parseInt(
numbers_[i] );
          }
      }
      finally {
        br.close();
      }

I think something like that should work =)

ArrayList> IndexOutOfBoundsException
What you want to do is first add something in a Since you are always reading the i value on the outer list we add a new array list on the outer loop. import java.util.ArrayList; public class abc { public static void main(String[] args) { ArrayList<ArrayList<Integer>> a = new ArrayList<ArrayList<Integer>>(); for(int i=0;i<10;i++) { a.

Add ArrayList to another ArrayList in java with Iterator
I'm fairly certain you wanted to add the book(s) with matching author's name to a new List. Something with an implicit iterator using a for-each loop List<Book> al = new ArrayList<>(); for (Book book : books) { if (authorName.equalsIgnoreCase(book.getAuthor())) { al.add(book); } } return al; or using an explicit Iterator like List<Book> al = new Arr
