Elements and Performance Criteria
ELEMENT | 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 the 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 HTML file and add an <APPLET> tag 3.2. Write the applet class file to match the HTML document that contains the <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 |

Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the following is essential: Assessment must confirm the ability to compile and run an applet that executes in Java-enabled browsers and allows users to customise the applet's operation. Evidence will include accepting user input and generating response based on the input. (e.g. in a web-browser 'shopping cart' situation, select multiple items and calculate the total cost of these items). To demonstrate competency in this unit the person will require access to: Java development environment Java compiler and interpreter Java enabled web browser |
Context of and specific resources for assessment | Performance of a broad range of skilled web-based applications, including requirements to evaluate and analyse current methods. The breadth, depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical and/or management requirements, evaluation and coordination would be characteristic. Assessment must ensure: The demonstration of competency may also require self-directed application of knowledge and skills, with substantial depth in some areas where judgement is required in planning and selecting appropriate equipment, services and techniques for self and others. Applications involve participation in development of strategic initiatives as well as personal responsibility and autonomy in performing complex technical operations or organising others. It may include participation in teams including teams concerned with planning and evaluation functions. Group or team coordination may also be involved. |
Method of assessment | The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1. Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency. Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process. The interdependence of units for assessment purposes may vary with the particular project or scenario. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICAB5161B Build a document using extensible mark-up language An individual demonstrating this competency would be able to: Demonstrate understanding of a broad knowledge base incorporating theoretical concepts, with substantial depth in some areas Analyse and plan approaches to technical problems or management requirements Transfer and apply theoretical concepts and/or technical or creative skills to a range of situations Evaluate information, using it to forecast for planning or research purposes Take responsibility for own outputs in relation to broad quantity and quality parameters Take some responsibility for the achievement of group outcomes Maintain knowledge of industry products and services Additionally, an individual demonstrating this competency would be able to: Demonstrate knowledge of Java programming, including theoretical concepts Apply solutions to Java applet problems Identify and apply skill and knowledge to Java solutions Identify and evaluate information from a variety of sources |
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. | |
