Java Steps to create a program with Eclipse

[Frank]

Eclipse is a professional IDE, which at first may seem complex development of our first programs.

All Eclipse program requires the creation of a "project", for this we must select from the menu of options:

Or from the toolbar of the Eclipse:

Now, the dialogue where we define our project name appears:

In the text field "Project Name" we enter as name: Project1 and leave all other options dialogue with the defaults. Click the "Finish" button.

Now in the window "Package" the project we've just created appears:

As a second step we will see that every Java program requires at least one class. To create a class we select from the menu of options:

Or from the toolbar of the Eclipse:

In the dialog that appears we must define the class name (in our first example we will call the class as Class1, then see that it is important to define a name that represents the goal of it), the other data of the dialogue we left with the default values:

After pressing the "Finish" button we have the file where we can code our first program:

Later we will see the files created in a project, now devote ourselves to encode our first program. In the editing window already we have the skeleton of a Java class that the Eclipse environment we created automatically.

public class Class1 {

}

All Java program should define the main function. This function must encode in the class, "Class1".

We proceed to type the following:

public class Class1 {

    public static void main(String[] parameter) {

        System.out.println("Hello World");

    }

}

That is we have encoded in the Eclipse IDE our first program:

As a last step we have to compile and run the program, this can be done from the menu of options:

Or from the toolbar of the Eclipse:

Unless there are coding errors, we'll see the result of running in a window of Eclipse called "Console" that appears at the bottom:

A pretty nice low level tutorial for beginners. Are you considering doing any more?
