How do I get started with Eclipse?

Java programs eclipse examples

When you create a Java project, this programming language allows you to organize your classes into packages. Packages help us to organize related classes under the same directory. At the operating system level, packages are nothing more than folders which contain classes and other files. However, creating them manually and managing them can be tedious. That is why in this article we will show you how to create a Java package in Eclipse.

This is probably the easiest way to create a Java package in Eclipse. Simply hover your mouse over the new Java package icon in the Toolbar. You can identify it as it has a little brown box icon. You can see where it is in Image #4.

As mentioned above, the eclipse will be seen primarily in North America and northeastern Russia; however, some areas of South America may see the eclipse during moonset, and some areas of eastern Asia and Australia may see the eclipse during moonrise.Advertising.

The eclipse in other regions of North America – most of the Southeast, from the High Plains to the West Coast and in most of New England and Canada – may be obscured by clouds. But not to be entirely discouraged.

Overall, NASA expects the eclipse to peak at 4:03 a.m. (Miami time) on Friday. The eclipse will begin at 1:03 a.m. (Miami), but the darkening of the moon will not be noticeable until 2:19 a.m., when the moon falls below the Earth’s umbra.

How to create a project in eclipse

We already know what Java is and we have configured our work environment, downloading both the JDK and the Eclipse IDE. Now we can get down to work with a first example, making the typical “Hello World”.

We open our Eclipse installation and the first thing it asks us is the location of our workspace in a window titled “Select workspace”. This is because Eclipse is not installed like the usual programs, but you copy the files to a folder on your computer and that’s it. This was explained in the previous article.

Our workspace is where we store all our projects. We can leave that path that Eclipse indicates by default. If you change it, just remember the physical folder you are setting up so you can indicate it the next times you open the IDE.

Once you open Eclipse, you will find a complex environment with several panels. Don’t be scared, although it seems that you don’t know what each thing is for, with a little experience you will be able to locate them and understand the usefulness of each panel.

This time the eclipse will darken some regions of the planet, where the best place to see it will be Antarctica, right in the Weddell Sea and throughout the event you will be able to see the Sun’s corona, also known as “The devil’s horns”.

This time Mexico will not be one of the places to see it, although it will darken regions mainly in Antarctica, some areas in the east of Argentina, the south of Chile, as well as some points of Australia, New Zealand, and Namibia. Other places to see it in the best way will be in Puerto Argentino, in the Falkland Islands and in Cape Town, South Africa.

In this type of solar eclipse, the Moon casts a shadow on the Earth, completely or partially blocking the light of the star in some areas, obscuring the terrain and can be classified in three different ways: total, partial and annular.

In the case of the total the observer sees the Moon entirely cover the disk of the Sun, for the partial the satellite only covers a part of the star and in the annular, the observer sees that the disk of the Moon does not cover the disk of the Sun, although their centers are well aligned.
