JDBC can also define as the platform-independent interface between a relational database and Java programming.

The world of Java and its functionalities have opened while a new dimension for programmers.

Java.util package provides a EnumMap class which is a specialized Map implementation for use with enum type keys. All of the keys in an enum map must come from a single enum type that is specified, explicitly or implicitly, when the map is created.

The Java has a number of methods and functions that are available for use with strings. These methods and functions are listed in alphabetical order.

Java.util package provides a PriorityQueue class where an unbounded priority queue based on a priority heap. The elements of the priority queue are ordered according to their natural ordering, or by a Comparator provided at queue construction time, depending on which constructor is used. A priority queue does not permit null elements. A priority queue relying on natural ordering also does not permit insertion of non-comparable objects.

Java.util package provides a BitSet class which implements a vector of bits that grows as needed. Each component of the bit set has a boolean value. The bits of a BitSet are indexed by nonnegative integers. By default, all bits in the set initially have the value false. One BitSet may be used to modify the contents of another BitSet through logical AND, logical inclusive OR, and logical exclusive OR operations.

Java.util package provides a Hashtable class which implements hash table and maps keys to value. Any non-null object can be used as a key or as a value. To successfully store and retrieve objects from a hashtable, the objects used as keys must implement the hashCode method and the equals method.

Java.util package provides a Dictionary class which is the abstract parent of any class, such as Hashtable, which maps keys to values. Every key and every value is an object. In any one Dictionary object, every key is associated with at most one value. Given a Dictionary and a key, the associated element can be looked up. Any non-null object can be used as a key and as a value.

Java.util package provides a LinkedList class which has Doubly-linked list implementation of the List and Deque interfaces. The class has all optional list operations, and permits all elements (including null). Operations that index into the list will traverse the list from the beginning or the end, whichever is closer to the specified index.

Java.util package provides a Scanner class. A simple text scanner parse primitive types and strings using regular expressions. A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. The resulting tokens may then be converted into values of different types using the various next methods.

The type casting is a method of converting the value of one data type to another data type. It is also known as type conversion. In Java, there are several kinds of conversions. However, in this tutorial we will focus only on two major types: Widening Type Casting, Narrowing Type Casting.

Threats related to Java programming language are increasing day by day. It also reminds about the old whack-a-mole arcade game. With the vulnerable version of Java, your computer becomes prone to malware or other threats.

JavaBeans is an object-oriented programming interface from Sun Microsystems that lets you build re-useable applications or program building blocks called components that can be deployed in a network on any major operating system platform.

This free course is totally independent. There are likewise no pre-necessities for this and all levels are welcome. The course additionally has intuitive activities and their answers remotely connected to it which will give you quick criticism so you can get the hang of everything too quick!
