Element |
Performance Criteria |
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
|
1. Create Java source file |
1.1 Create a file with a text editor 1.2 Create a sub-class of the class java.applet.Applet 1.3 Ensure that applet sub-class implements at least one of the following methods: init and paint 1.4 Define classes that contain instance variables, methods and local variables 1.5 Ensure that the init method initialises instance variables and constructs any graphical interface used in the applet sub-class 1.6 Implement the paint and update methods to manage output that is drawn in the applet window 1.7 Incorporate event handling methods 1.8 Implement code that allows a user to enter values and assigns these values to variables 1.9 Use available graphical user interface (GUI) components to allow user interaction with the applet 1.10 Specify and load images and sounds 1.11 Include comments to describe the behaviour of the applet |
|
2. Compile source file |
2.1 Use a Java compiler to compile the file 2.2 Correct errors detected by the compiler 2.3 Confirm basic correctness of file to ensure that all variables have been initialised 2.4 Ensure compiler creates a class file and the class is interpreted correctly |
|
3. Run applet |
3.1 Create and name a hypertext markup language (HTML) file and add APPLET tag 3.2 Write the applet class file to match the HTML document that contains APPLET tag 3.3 Confirm that the applet loads and executes correctly 3.4 Identify and correct run-time errors 3.5 Identify and correct logic errors 3.6 Ensure that the appearance of the applet window renders it accessible and intuitive for the user, and that its design complies with organisational standards 3.7 Ensure that user interaction is implemented efficiently and effectively |

Context of and specific resources for assessment |
Assessment must ensure access to:
|
|
Method of assessment |
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
|
|
Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
