Slide 1Welcome | Welcome to the spoken tutorial on Programming Features of Eclipse.
|
Slide 2Learning Objectives
|
In this tutorial, we will learn how to use
the user- friendly programming features of Eclipse effectively.
|
Slide 3Tools Used | For this tutorial we are usingUbuntu 11.0, JDK 1.6, and Eclipse 3.7.0 |
Slide 4Pre-requisites | To follow this tutorial,
Eclipse must be installed in your system, and You must have a basic knowledge of writing a simple java program in Eclipse.
|
Slide 5Programming Features Used in Eclipse IDE | Eclipse IDE supports many user friendly features such as
Auto completion, Syntax highlighting, Error dialog box, and Shortcut keys. We will look into each of these features in detail.
|
Switch to Eclipse IDE Interface(Auto completion)public class Features{ public static void main(string args[]) { {}} | I have already created a class named Features and added the main method.
|
Highlight main method
Hit Enter
|
Now, type an opening brace inside main method and press Enter.
|
Type ( inside the braces | It also completes every feature that works in pairs.
For example parentheses.
|
Type ) | Also note that if we are accustomed to type the closing parenthesis also, then it takes care of it by not adding the extra closing parenthesis.
|
Type “ inside the parentheses | It works in similar fashion with double quotes also.
|
Auto-completion is a very versatile feature and helps a lot in maintaining the structure of the code and also prevents typing errors like missing closing braces, missing closing parentheses and missing closing quotes. | |
Remove everything in the main function and type
System.out.println();
|
Remove all that we just typed.
|
Point to the drop down list.** We can see the drop down list in the eclipse after the System. | The Eclipse displays a drop-down list.
|
Select out and hit Enter.
|
Select out and press Enter.Again, type dot. |
Point to the drop down list. | Now Eclipse will provide suggestions like append,close,print, println() and so on. |
Select println() and press Enter. | Select println() and press Enter. |
Eclipse IDE
|
Let us move on to the Syntax highlighting feature of Eclipse.While writing the program, certain keywords will get highlighted automatically. |
Highlight class name
|
You can see the class name keyword highlighted in pink colour.
The method name keyword is highlighted in blue colour. This Syntax highlighting feature helps us to differentiate between various keywords. |
Eclipse IDEpublic class HelloWorld {public static void main(String args[]) { X System.out.println("Hello World")}}Remove the ;
|
Eclipse also helps the programmer to find out the errors.In a program, an Error is denoted by a red cross symbol. Now, in this program let us remove the semicolon from the output statement. |
Point to the red cross. | A red cross symbol appears in the beginning of the output statement. |
Hover the mouse over the red cross symbol. | When we hover the mouse over the Cross symbol, we see the error details. |
Point to the errors and solution. | The solution to resolve the error is also shown. |
Run it.
Point to the Error Dialog Box |
If we proceed to the run without fixing errors, it warns us.
|
Click Proceed
|
Let us proceed for now.
|
Keep the Eclipse IDE Window open. | The next programmer friendly feature of eclipse is the shortcut-keys. |
The common shortcut-keys in any program are Ctrl+S for saving and Ctrl+O for opening.
| |
Eclipse IDE
|
Control F11. is the shortcut for running the code. Let us try it now.
We see the output. |
Click Run and point to Debug | The shortcut keys for other options can be found by looking at the menu.
|
This is just a small but most commonly used list of the programming features of Eclipse. We shall look at more, in subsequent tutorials. | |
Slide 6Summary | We have come to the end of this tutorial. In this tutorial, we learnt how to use programming features of Eclipse such as
Auto completion, Syntax highlighting, Error dialog box, and Shortcut keys, effectively. |
Slide 7
Assignment |
Now, do an Assignment on what we learnt. Write a simple Java program with a class that prints “Hello” as the output on your screen.
Apply all the programming features of Eclipse. Also observe the corresponding changes which we discussed. |
