Time Narration
00:02 Welcome to the tutorial on Programming Features of Eclipse.
00:07 In this tutorial, we will learn about
00:10 the user- friendly programming features of Eclipse
00:15 For this tutorial we are usingUbuntu 11.0, JDK 1.6, and Eclipse 3.7.0
00:23 To follow this tutorial, you must have
00:26 Eclipse installed on your system, and
00:28 You must know how to write a simple java program in Eclipse.


00:32 If not, for relevant tutorial please visit our website as shown.
00:40 Eclipse IDE supports many user friendly features such as
00:44 Auto completion,
00:45 Syntax highlighting,
00:46 Error dialog box, and
00:48 Shortcut keys.
00:49 We will look into each of these features in detail.



00:59 I have created a class named Features and added the main method.


01:05 we will first look at ' Auto completion feature in Eclipse.


01:10 Inside the main method type an opening brace and hitEnter.


01:17 We can see that it automatically sets the corresponding closing braces and also positions the cursor with indentation.
01:25 It also completes every feature that works in pairs.
01:29 For example parentheses, type open parentheses


01:35 We can see that we only have to type the open parenthesis and eclipse automatically adds the closing parenthesis.
01:42 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.


01:52 I’m now typing the closing parenthesis and note that only the cursor moves to the right and the extra parenthesis is not added.
02:02 It works in similar fashion with double quotes also.


02:06 Type opening quotes and it automatically closes the quotes.
02:12 If we are accustomed to type the closing quotes also, it takes care of it by not adding the extra quote.
02:19 I know typing the quotes and notice that the cursor moves to the right with the extra quotes is not added
02:27 Auto-completion is a very versatile feature and helps a lot in maintaining the structure of the code
02:32 and also prevents typing errors like missing closing braces, missing closing parentheses and missing closing quotes.
02:44 The next programming feature we will look at is suggestion.
02:48 Remove all that we just typed.
02:54 We will type the output statement to print the word “hello”. System dot'.


03:07 Notice that Eclipse displays a drop-down list.


03:11 The list contain suggestions like err, in,out,console all sought of possible completion



03:19 Scroll down to out and press Enter.Again, type a dot.
03:28 Now Eclipse will provide suggestions from the out module.
03:33 Scroll down to println() and press Enter.Now inside the paranthesis in quotes typeHello
03:57 next features we will looking at is the Syntax highlighting feature .
04:02 Note that the keyword public class, public static void are all in different color
04:09 Also note that the word Hello is in blue color indicating that this is the string.
04:16 This Syntax highlighting feature helps us to differentiate between keywords and different parts of the code
04:27 Eclipse also helps the programmer to find out errors.
04:31 In a program, Error is denoted by a red cross symbol on the left margin.
04:36 In this program we can see there is an error and mouse hover on the error
04:46 We can see that the error says; semi-colon missing and the solution to resolve the error is also shown.
04:57 If we proceed to the run without fixing the error right click select run as java application


05:12 We have a Error Dialog Box. indicating that there is an error asking should we proceed or not
05:17 For now let us proceed. We notice that there is output indicating that there is an error and
05:35 when we go to problem console all the problem with possible solution are listed


05:43 So Let us resolve the error by adding a semi-colon. Ctrl, S to save
05:53 The next programmer friendly feature of eclipse is the shortcut-keys.
06:01 The common shortcut-keys in any program are Ctrl+S for saving and Ctrl+O for opening.
06:07 Eclipse has shortcut keys for many such commonly used functions.
06:12 Control F11. is the shortcut for running the code.
06:16 Let us try it now.Hold Ctrl and press F11 and we see that the code is run and the output Hello has been printed


06:27 The shortcut keys for other options can be found by looking at the menu. Click Run


06:33 And Notice that on the right end of the option, there is the shortcut is given.


06:40 So the shortcut key for Debug is F11
06:45 This is just a small but most commonly used list of the programming features of Eclipse. We shall look at more features, in subsequent tutorials.
06:56 this brings us to the end of this tutorial. In this tutorial, we have learnt how to use programming features of Eclipse such as
07:04 Auto completion,
07:05 Syntax highlighting,
07:06 Error dialog box, and
07:07 Shortcut keys.
07:10 As an Assignment for this tutorial .
07:12 Write a simple program with a class that prints “Hello”
07:17 In the process Apply all the programming features of Eclipse.
07:22 observe its functions
