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 using Ubuntu 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 Syntax highlighting
00:46 * Error dialog box and
00:48 * Shortcut keys.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 hit Enter.
01:17 We can see that it automatically sets the corresponding closing brace and also positions the cursor with an 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 quote and notice that the cursor moves to the right with the extra quote 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 contains 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 parentheses, in quotes, type Hello.
03:57 The next feature we will be looking at is the Syntax highlighting feature.
04:02 Note that the keywords public class, public static void are all in a different color.
04:09 Also note that the word Hello is in blue color indicating that this is a string.
04:16 This 'syntax highlighting' feature helps us to differentiate between key words and different parts of the code.
04:27 Eclipse also helps the programmer to find out errors.
04:31 In a program, an 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 an 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 problems with possible solutions are listed.
05:43 So Let us resolve the error by adding a semicolon. 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 a shortcut 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 Syntax highlighting
07:06 Error dialog box and 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 the functions.
07:25 To know more about the Spoken Tutorial project,

07:30 It summarizes the project.
07:33 If you do not have good bandwidth, you can download and watch it.
07:37 The Spoken Tutorial Team:
07:39 Conducts workshops using spoken tutorials.
07:42 Gives certificates for those who pass an online test.
