Similar to the InputStream class, the abstract OutputStream class is a superclass of all classes representing an output stream of bytes. A few examples of these subclasses are:

Java 

The File Copy program accepts two command-line parameters and copies the contents of the file specified by the first parameter to the filename specified in the second parameter.

The read method we used in the previous post is in fact defined in the InputStream class. The FileInputStream class that extends from the InputStream class inherits this method.

Java provides a rich set of classes for I/O. A high-level class diagram for the I/O class library is shown here:

Java 

One of the important set of classes comprised in Java API is the java.io package. This is one of the core packages of the Java language and was a part of JDK 1.0. These classes facilitate the input/output functionality in our programs.

In previous posts, we have learnt how to find the length of the arrays and how to clone an array. Now here we learn how to find out the class of an array.

To make a copy of an array, we call the clone method on the array object. This is illustrated in this implementation:

When we declare an array in Java, it is treated as an object of an internal class that defines useful attributes and methods.

So far we have seen the declaration and use of rectangular arrays. Java allows us to create non-rectangular arrays.

Multidimensional arrays, as the name suggests, contain more than one dimension. You can create two-dimensional, three-dimensional, and n-dimensional arrays in Java (where n is any natural number).

In my previous post, we have already learned how to declare an array, allocate the space for its elements, and how to modify and access its elements. Now we learn how to initialize a java array.

We create arrays when we want to operate on a collection of variables of the same data type or pass them all around together.

In 2014, Oracle Corporation released Java 8 on 18 March, which was another milestone release for the Java ecosystem.

Java SE 7 was released on 7 July 2011. Java SE 7 is the major release to the Java SE platform, which came a long time after its previous release

J2SE 5.0 was released on 30th September 2004. Developed under JSR 176, Tiger added a number of significant language features, including the for-each loop, generics, autoboxing, and var-args.

Previously we have seen JDK 1.0 and its features. We also examine the JDK 1.1 release and some its major API’s and classes.

The introduction of the JVM in the architecture also helped developers in creating robust and secure Java applications.

Mapper class is responsible for providing implementations for mapping jobs in MapReduce.

HDFS is one of the two main components of the Hadoop framework; the other is the computational paradigm known as MapReduce.

Look around at the technology we have today, and it's easy to come to the conclusion that it's all about data. Organizations are flooded with data.

The internet may be a major force these days, restructuring our economic, social political & cultural Systems.

Programming instruments are likewise programming as projects or applications that product designers (otherwise called developers, coders, programmers or programming engineers)
