IGNOU Registrar information

A registrar is an official designation in university, college and school who maintain student's record. 

Typically, a registrar processes registration requests, enforces the rules, schedules classes and maintains class lists, enforces the rules for entering or leaving classes, and keeps a permanent record of grades and marks of every student. In institutions with selective admission requirements, a student only begins to be in connection with the registrar's official actions after admission.

New features in java language in Java-9 or JDK-9 release

The major change in Java SE 9 is its module system. Other than this there are several small language changes as well in Java SE 9.

As we already know on 21st Sept 2017 JDK 9 or Java 9 has been release in market. Today we will see what all new programming features introduced in Java SE-9.

• You can now declare a private method in a Interface class. This allows non-abstract methods of an interface to share code between them. 

For Example: 

public interface AccountOp{

public static final String NAME="wellDo";

//default method of interface

public default void foot(){}

//private method within interface

private void displayAge();

}

• Underscore character no more legal for identifier name. Your source code will not compile if you use underscore character ["_"] in an identifier name[variables, methods, classes, packages and interfaces]. e.g. String ras_name; interface Local_Home; public void gender_Test(); are the illegal in Java 9/JDK 9.

• Allow effectively final variables to be used as resources in the try-with-resources statement. If you already have a resource as a final or effectively final variable, you can use that variable in a try-with-resources statement without declaring a new variable. An "effectively final" variable is one whose value is never changed after it is initialized.

For example, you declared these two resources:

        // A final resource

        final Resource resource1 = new Resource("resource1");

        // An effectively final resource

        Resource resource2 = new Resource("resource2");

In Java SE 7 or 8, you would declare new variables, like this:

        try (Resource r1 = resource1;

             Resource r2 = resource2) {

            ...

        }

In Java SE 9, you don’t need to declare r1 and r2:

// New and improved try-with-resources statement in Java SE 9

        try (resource1;

             resource2) {

            ...

        }

• @SafeVarargs annotation is allowed on private instance methods.

The @SafeVarargs annotation can be applied only to methods that cannot be overridden. These include static methods, final instance methods, and, new in Java SE 9, private instance methods.

• You can use diamond syntax in conjunction with anonymous inner classes.

Types that can be written in a Java program, such as int or String, are called denotable types. The compiler-internal types that cannot be written in a Java program are called non-denotable types.
Non-denotable types can occur as the result of the inference used by the diamond operator. Because the inferred type using diamond with an anonymous class constructor could be outside of the set of types supported by the signature attribute in class files, using the diamond with anonymous classes was not allowed in Java SE 7.
In Java SE 9, as long as the inferred type is denotable, you can use the diamond operator when you create an anonymous inner class.

For more detail information please refer the Java official doc.

Key Changes in Java 9

On 21st September 2017 Oracle released new version of Java/JDK version 9.

in this tutorial we will see what all are the key changes in Java 9 and how it will improve the performance of an application and who this things are going to help a programmer to write good programs.

Java Platform Module System

Introduces a new kind of Java programming component, the module, which is a named, self-describing collection of code and data. This module system have following features:

1. Introduces the modular JAR file, which is a JAR file with a module-info.class file in its root directory.
2. Introduces a new optional phase, link time, which is in-between compile time and run time, during which a set of modules can be assembled and optimized into a custom runtime image.
3. Adds options to the tools javac, and java where you can specify module paths, which locate definitions of modules.
4. Introduces the JMOD format, which is a packaging format similar to JAR except it can include native code and configuration files.
5. The JDK itself has been divided into a set of modules. 

For more detail information you can download Java 9 release notes from here.

New Version-String Scheme

Provides a simplified version-string format that helps to clearly distinguish major, minor, security, and patch update releases.

The new version-string format is as follows: 

$MAJOR.$MINOR.$SECURITY.$PATCH

For more detail see version-string format or browse the link from reference.
