Slide 5

Introduction to Eclipse

Eclipse is an Integrated Development Environment


It is a tool on which one can write, debug and run java programs easily.

Press Alt + F2

Type eclipse

Now let us open Eclipse.


Press Alt F2 and in the dialog box, type eclipse and hit enter.

Hover the mouse over Eclipse Workspace Launcher


We have a Workspace Launcher dialog box.


A workspace is a location where all the project realated data and the eclipse related files are stored.


There is already a location which is the default location.


Using the browse feature, a different directory can also be selected.


For now let us proceed with the default directory.

Click on OK. Click OK to proceed.
Hover the mouse over the Welcome Page. and We have the Welcome to Eclipse page.
Click on Workbench Click Workbench which is at the top-right corner of the page.
And here we have Eclipse IDE. Now let us add a project.
File -> New -> Project go to File


New and select Project

In the list of projects, select Java Project
Click Next Also note that, for most of our tutorials, we will be using java project. Click Next
Type EclipseDemo in the name field In the project name, type EclipseDemo
Notice an option that says use default location
if this option is selected, all the EclipseDemo project data is stored in the default workspace.
If it is unselected, using the browse feature, a different location can also be selected.

For now we’ll use the default location.

Click Finish click Finish located at the bottom right corner of the Wizard.
Select the checkbox and click Yes We get the Open Associated Perspective dialog box.


A perspective refers to the way items are arranged in Eclipse.


The dialog box is suggesting a perspective that is suited for Java development.


Select remember my decision and click Yes.

Here we haveeclipse IDE in the project. Now let us add a class to the project.
Right click on the project,

New -> Class

Right click on the project, new select class
Type DemoClass in name field In the class name, give DemoClass
Notice that in modifiers, we have two options,

public and default

For now, leave it as public.
The other options will be discussed in subsequent tutorials.
Select public static void main And in the list of stubs select the option that sayspublic static void main
The other options will be discussed in subsequent tutorials.
click Finish click Finish located at the bottom right corner of the wizard.
Here we have the class file.
Notice that there are a lot of partitions. These are called portlets.
click on Package Explorer portlet We have the Package Explorer portlet that behaves like a File Browser
click on Editor portlet We have the Editor portlet in which we write the code.
click on Outline portlet And the Outline portlet it gives a hierarchy of the project.
resize the portlets Each portlet can also be resized
minimize the portlets They can also be minimized by using the minimize button
restore the portlets They can be restored by using the restore button.
minimize other portlets Now let us minimize other portlets and focus on the Editor.
As we can see, there is already some code, Eclipse has generated for us.
The code generated here depends on the options we select, while creating the class.
Now let us add a print statement here.
System.out.println(“Hello Eclipse”); Type System.out.println(“Hello Eclipse”).
Add a semicolon at the end of the statement.
Save the file by clicking File and select Save
Alternatively, you can use the shortcut Control S also
To run this program, right click on the editor, go to run as and select java applicationapplication
We see that if somethng is printed, the Output console shows the output.
If our code had problems, the problem would have been shown on the Problems portlet
Here is how you write and run a Java program in Eclipse
Exit the Eclipse window and show Slide window
