A few main points about creating and accessing ArrayList Java class 5. Print Elements of ArrayList. You can print one by one without using loop but the problem is because you are using object type so you cannot print objects unless you use a toString method in the class even if you don’t use Arraylist it wont work if you want to print object, unless you use toString method You can also traverse the ArrayList using a for-each loop or the enhanced for loop. The features of Java stream are – A stream is not a data structure instead it takes input from the Collections, Arrays or I/O channels. To print elements, first we’ll create a String ArrayList and store weekdays name as strings into it and display them using following ways: For-loop; For-each loop; Using iterator; Using List-iterator; Here is a string ArrayList.

Prior to Java 8, it did not include lambda expressions. A stream is a sequence of objects that supports various methods which can be pipelined to produce the desired result. Tutorials, Source Codes, SCJP, SCWCD and Ebooks. If you override the toString(): string method to your data class, which is jobSchedule (rename to JobSchedule), you will be able to do: The number of items in an empty ArrayList is 0.
