The primary reason behind development of Java was to bring mobility and protection function into a computer terminology. Beside these two major functions, there were many other functions that performed an part in moulding out the ultimate form of this excellent terminology. Those functions are :
Java is simple to learn and its structure is quite simple, clean and clear and understandable.The complicated and uncertain ideas of C++ are either left out in Java or they have been re-implemented in a better way.
Eg : Suggestions and Owner Over-loading are not there in java but were a significant part of C++.
2) object Oriented:
In java everything is object which has some data and behavior. Java can be easily prolonged as it is based on object Design.
Java creates an effort to remove mistake vulnerable requirements by focusing mainly on gather time mistake verifying and playback verifying. But the primary areas which Java enhanced were Storage Control and mishandled Exclusions by presenting automated Garbage collection and Exemption Managing.
4) System Independent:
Unlike other development ‘languages’ such as C, C++ etc which are collected into platform specific devices. Java is assured to be write-once, run-anywhere terminology.
On selection Java system is collected into bytecode. This bytecode is platform individual and can be run on any device, plus this bytecode structure also provide protection. Any device with Java Runtime Atmosphere can run Java Applications.
Java is properly secured because:
No precise pointer
Applications run inside exclusive device sand pit.
Classloader- contributes protection by splitting the program for the sessions of a nearby data file system from those that are brought in from system sources.
Bytecode Verifier- assessments the system code pieces for unlawful system code that can breach accesss right to things.
Security Manager- decides what sources a class can accessibility such as studying and writing to a nearby hard drive.
Robust essentially implies powerful. Java uses powerful memory management. There are lack of pointers that prevents protection problem. There is automated garbage selection in java. There is exception handling and type verifying procedure in java. All these points creates java effective.
There is no execution reliant functions e.g. size of basic types is set.
We may bring the java bytecode to any platform.
Java is quicker than conventional presentation since byte system code is “close” to local system code still somewhat more slowly than a collected terminology (e.g., C++)
We can create allocated programs in java. RMI and EJB are used for developing allocated programs. We may access data files by contacting the methods from any device on the internet.
A thread is like another system, performing simultaneously. We can create Java programs that deal with many projects at once by interpreting several discussions. The benefit of multi-threading is that it stocks the same memory. Threads are necessary for multi-media, Web programs etc.
New Features of JAVA 8:
Below mentioned are some of the main improvements done as a part of Java 8 launch. Just go through them quickly, we will discover them in details later.
Improved Efficiency by giving Optionally available Sessions feature, Lamda Expression, Sources etc.
Ease of Use:
Improved Polyglot development. A Polyglot is a program written in a form which is legitimate in several development ‘languages’ and it works the same functions in several development ‘languages’. So Java now facilitates such type of development technique.
Improved Security and performance.
Java 8 is an excellent launch of the world’s #1 development system. It has a huge update to the Java development model and a synchronized progress of the JVM, Java language, and collections. Java 8 contains features for efficiency, ease of use, enhanced polyglot development, security and enhanced performance. Welcome to the latest version of the biggest, open, standards-based, community-driven system.
