-
Assume the following:
- Missing package and import statements: If the sample code does not include package or import statements, and the question does not explicitly refer to these missing statements, then assume that all sample code is in the same package, or import statements exist to support them.
-
No file or directory path names for classes: If a question does not state the file names or directory locations of classes, then assume one of the following, whichever will enable the code to compile and run:
- All classes are in one file
-
Each class is contained in a separate file, and all files are in one directory
- Unintended line breaks: The sample code might have unintended line breaks. If you see a line of code that looks like it has wrapped, and this creates a situation where the wrapping is significant (for example, a quoted String literal has wrapped), assume that the wrapping is an extension of the same line, and the line does not contain a hard carriage return that would cause a compilation failure.
- Code fragments: A code fragment is a small section of source code that is presented without its context. Assume that all necessary supporting code exists and that the supporting environment fully supports the correct compilation and execution of the code shown and its omitted environment.
- Descriptive comments: Take descriptive comments, such as "setter and getters go here," at face value. Assume that the correct code exists, compiles, and runs successfully to create the described effect.
Apart from the above syllabus, it is beneficial to have practical training and hands-on experience in Java. The questions asked in the exam will test your ability to apply your knowledge in real-world situations.
