How Garbage Collection works in Java. I have read many articles on Garbage Collection in Java, some of them are too complex to understand and some of them don’t contain enough information required to understand garbage collection in Java.
Then I decided to write my own experience as an article or you call tutorial about How Garbage Collection works in Java or what is Garbage collection in Java in simple word which would be easy to understand and have sufficient information to understand how garbage collection works in Java. This article is in continuation of my previous articles How Classpath works in Java and How to write Equals method in java and before moving ahead let's recall few important points about garbage collection in java: When an Object becomes Eligible for Garbage Collection An Object becomes eligible for Garbage collection or GC if its not reachable from any live threads or any static references in other words you can say that an object becomes eligible for garbage collection if its all references are null.
10 example of using ArrayList in Java >>> Java ArrayList Tutorial. ArrayList in Java is most frequently used collection class after HashMap in Java.
Java ArrayList represents an automatic re-sizable array and used in place of array. Since we can not modify size of an array after creating it, we prefer to use ArrayList in Java which re-size itself automatically once it gets full. ArrayList in Java implements List interface and allow null. Java ArrayList also maintains insertion order of elements and allows duplicates opposite to any Set implementation which doesn't allow duplicates. ArrayList supports both Iterator and ListIterator for iteration but it’s recommended to use ListIterator as it allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the Iterator's current position in the list. ArrayList has been modified in Java5 (Tiger) to support Generics which makes Java ArrayList even more powerful because of enhanced type-safety.

Collections Framework Overview. Introduction The Java 2 platform includes a collections framework.
A collection is an object that represents a group of objects (such as the classic Vector class). A collections framework is a unified architecture for representing and manipulating collections, allowing them to be manipulated independently of the details of their representation. The primary advantages of a collections framework are that it: Reduces programming effort by providing useful data structures and algorithms so you don't have to write them yourself.Increases performance by providing high-performance implementations of useful data structures and algorithms. The collections framework consists of: Collection Interfaces - Represent different types of collections, such as sets, lists and maps.
Collection Interfaces There are fourteen collection interfaces. Many of the modification methods in the collection interfaces are labeled optional. Be of a particular type.Be non-null.Obey some arbitrary predicate. Oracle JDeveloper.
