| 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 |
| 07:25 | To know more about the Spoken Tutorial project, |
