|-
| style="border:0.035cm solid #000000;padding:0cm;"| Slide 1'''Welcome'''
| style="border:0.035cm solid #000000;padding:0cm;"| Welcome to the spoken tutorial on '''Programming''' '''Features of Eclipse.'''

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Slide 2'''Learning Objectives'''

| style="border:0.035cm solid #000000;padding:0cm;"| In this tutorial, we will learn how to use

the user- friendly programming features of Eclipse effectively.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Slide 3'''Tools Used'''
| style="border:0.035cm solid #000000;padding:0cm;"| For this tutorial we are usingUbuntu 11.0, JDK 1.6, and Eclipse 3.7.0

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Slide 4'''Pre-requisites'''
| style="border:0.035cm solid #000000;padding:0cm;"| 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.

If not, for relevant tutorial please visit our website which is as shown.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Slide 5'''Programming Features Used in Eclipse IDE'''
| style="border:0.035cm solid #000000;padding:0cm;"| 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.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Switch to Eclipse IDE Interface(Auto completion)'''public class Features'''{ '''public static void main(string args<nowiki>[])</nowiki>''' '''{''' {}'''}'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| I have already created a class named '''Features''' and added the main method.

Now, we will first look at the use of the Auto completion feature in Eclipse.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Highlight '''main '''method

Type {

Hit '''Enter'''

'''<nowiki>*</nowiki>we could see that the highlighted part automatically gets invoked.'''
| style="border:0.035cm solid #000000;padding:0cm;"| Now, type an opening brace inside '''main''' method and press '''Enter'''.

We can see that it automatically sets the corresponding closing brace and also positions the cursor with indentation.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Type '''(''' inside the braces
| style="border:0.035cm solid #000000;padding:0.176cm;"| It also completes every feature that works in pairs.

For example parentheses.

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

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Type ''')'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| 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.

I’m now typing the closing parenthesis and we can see that only the cursor moves to the right and the extra parenthesis is not added.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Type '''“''' inside the parentheses
| style="border:0.035cm solid #000000;padding:0.176cm;"| It works in similar fashion with double quotes also.

Type a quote inside the parentheses and we see that it adds the closing quote. If we are accustomed to typing the closing quote, it takes care of it by not adding the extra quote.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"|
| style="border:0.035cm solid #000000;padding:0.176cm;"| 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.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| '''Remove everything in the main function and type'''

''System.out.println();''

''public class Features''{ public static void main(string args<nowiki>[]) </nowiki>'''{''' System.out.print("hello");} '''}  '''
| style="border:0.035cm solid #000000;padding:0cm;"| Remove all that we just typed.

The next programming feature we will look at is '''suggestion'''.We will type the output statement to print a word “hello”.So type the keyword '''System '''and then a''' dot'''.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Point to the '''drop down list.<nowiki>** </nowiki>We can see the drop down list in the eclipse after the System.'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| The Eclipse displays a drop-down list.

The list contain some suggestions like '''err, in,out,console '''for completing the program.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| '''Select out '''and hit '''Enter.'''

Type '''dot'''
| style="border:0.035cm solid #000000;padding:0cm;"| Select '''out''' and press '''Enter'''.Again, type '''dot.'''

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Point to the''' drop down list.'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| Now Eclipse will provide suggestions like '''append,close,print, println() and so on.'''

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Select '''println()''' and press '''Enter'''.
| style="border:0.035cm solid #000000;padding:0.176cm;"| Select '''println()''' and press '''Enter'''.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Eclipse IDE

| style="border:0.035cm solid #000000;padding:0cm;"| Let us move on to the '''Syntax highlighting''' feature of Eclipse.While writing the program, certain keywords will get highlighted automatically.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Highlight '''class name'''

Highlight '''method'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| 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.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Eclipse IDEpublic class HelloWorld {public static void main(String args<nowiki>[]) </nowiki>{ X System.out.println("Hello World")}}'''Remove the ; '''

| style="border:0.035cm solid #000000;padding:0cm;"| 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.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Point to the '''red cross.'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| A red cross symbol appears in the beginning of the output statement.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| '''Hover the mouse over the red cross symbol.'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| When we hover the mouse over the Cross symbol, we see the error details.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Point to the errors and solution.
| style="border:0.035cm solid #000000;padding:0.176cm;"| The solution to resolve the error is also shown.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Run it.

Point to the''' Error Dialog Box'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| If we proceed to the '''run''' without fixing errors, it warns us.

The error details are displayed in the '''Error Dialog Box.'''

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Click '''Proceed'''

Add semicolon at the end of print statement.
| style="border:0.035cm solid #000000;padding:0.176cm;"| Let us proceed for now.

In the problems portlet, all the errors with fixes are shown.

Let us resolve the error by adding semi-colon

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Keep the Eclipse IDE Window open.
| style="border:0.035cm solid #000000;padding:0cm;"| The next programmer friendly feature of eclipse is the shortcut-keys.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"|
| style="border:0.035cm solid #000000;padding:0.176cm;"| The common shortcut-keys in any program are Ctrl+S for saving and Ctrl+O for opening.

Eclipse has shortcut keys for many such commonly used functions.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Eclipse IDE

Press '''Ctrl'''+'''F11'''

Point to the output screen
| style="border:0.035cm solid #000000;padding:0cm;"| '''Control''' '''F11'''. is the shortcut for running the code. Let us try it now.

We see the output.

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"| Click '''Run''' and point to '''Debug'''
| style="border:0.035cm solid #000000;padding:0.176cm;"| The shortcut keys for other options can be found by looking at the menu.

Notice that on the right end of the option, the shortcut is given.

So the shortcut key for '''Debug''' is '''F11'''

|-
| style="border:0.035cm solid #000000;padding:0.176cm;"|
| style="border:0.035cm solid #000000;padding:0.176cm;"| This is just a small but most commonly used list of the programming features of Eclipse. We shall look at more, in subsequent tutorials.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| Slide 6'''Summary'''
| style="border:0.035cm solid #000000;padding:0cm;"| 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.

|-
| style="border:0.035cm solid #000000;padding:0cm;"| '''Slide 7'''

'''Assignment '''
| style="border:0.035cm solid #000000;padding:0cm;"| 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.
