Hi Friends

By the grace of ALLAH I am fine and I hope that you will be same.This is my first post in this community. Today i thought that i will share about knowledge of diference between packages and interface.

Packages and Interface

Packages and Interfaces each acts as a container. The content material in applications and interfaces may be utilized by the training via way of means of uploading and enforcing it correspondingly.



source

The simple distinction among applications and interfaces is that a package deal includes a set of training and interfaces whereas, an interface includes strategies and fields. Let’s take a look at a few different variations with the assist of contrast chart.

Definition of Packages

Packages are series or organizatios of the style of training and interfaces. The training in applications are associated with every different in a few scope or via way of means of inheritance. You also can create your package deal and use it to your program.

Creating a package deal.

For developing a package deal simply observe the subsequent steps.

Open a report after which claim the call of the package deal on the pinnacle of the report, like [ package package_name; ] the package deal call is the call you need to present to the package deal.
Next, you outline a magnificence which you need to position withinside the package deal, and take into account which you claim it public.
Save the report as a .java report after which bring together the report, then” .magnificence” is attain for that report.
To create a package deal for this report the command used is “javac -d . file_name.java. You can see that the package deal is created containing a ” .magnificence” report withinside the contemporary listing. To region it in discern listing use “javac -d . . file_name.java” command.
You also can create a subpackage via way of means of putting forward subpackage call as [ package package_name1. package_name2; ] on the pinnacle of the report.
package deal Mypackage;
public magnificence myclassapproach displayMypackage of sophistication myclass of package deal Mypackage");
}

Definition of Interface

Interface is a sort of a magnificence, however, differs in a feel that the strategies declared withinside the interface are summary meaning the strategies are simplest declared however now no longer described. The fields withinside the interface are constantly public, static, final. The fields ought to be initialized on the time of announcement.



source

The strategies declared via way of means of the interface are described via way of means of the magnificence which implements that interface in line with its requirement. As the strategies withinside the interface do now no longer carry out any function, so there may be no need of making any item of the interface. Hence, no item may be created for the interface.

The interface also can inherit the opposite interface however, the magnificence inheriting such an interface ought to additionally put in force all of the strategies of the inherited interface. As the fields are initialized on the time in their announcement withinside the interface, so there may be no want of constructor withinside the interface hence, the interface doesn’t incorporate any constructor. Let’s see the instance of making and the use of an interface.

interface Area glide pi= 3.14;
go with the flow find_area(go with the flow a, go with the flow b)
magnificence Circle implements Areaglide find_area(go with the flow a, go with the flow b)
Class Shapes{
public static void main(string args[ ]){
Area A=new Area ( );
Circle C= new circle ( );
A=C;
go with the flow F= Area. find_area(10,10);
system.out.println("Area of the circle is :" +F);
}
In above code, we had created an interface Area, and the magnificence Circle has carried out the interface Area. The field “pi” has been initialized withinside the interface on the time of its announcement. The magnificence Circle has described the summary technique of the magnificence location in line with its requirement.

Both applications and interface are the containers. Package reduces the scale of the code as we simply import the magnificence for use in place of once more outline it. Whereas the interface reduces the confusions came about at the same time as more than one inheritances due to the fact withinside the case of more than one inheritances the inheriting magnificence has now no longer to determine that definition of which technique it ought to inherit alternatively it defines its own.
