• Write code that declares, constructs, and initialises arrays of any base type using any of the permitted forms both for declaration and for initialisation.
• Declare classes, inner classes, methods, instance variables, static variables, and automatic (method local) variables making appropriate use of all permitted modifiers (such as public, final, static, abstract, and so forth).
• State the significance of each of these modifiers both singly and in combination, and state the effect of package relationships on declared items qualified by these modifiers.
• For a given class determine if a default constructor will be created and if so state the prototype of that constructor.
• State the legal return types for any method given the declarations of all related methods in this or parent classes.

• Write code using if and switch statements and identify legal argument types for these statements.
• Write code using all forms of loops including labeled and unlabeled use of break and continue and state the values taken by loop control variables during and after loop execution.
• Write code that makes proper use of exceptions and exception handling clauses (try, catch, finally) and declares methods and overriding methods that throw exceptions.

[from eindia] With a broad array of features ranging from online shopping to matrimonial match-making to free e-mail, eIndia provides a practical and unique experience for millions of non-resident Indians around the world as well as the growing number of non-Indians, uncovering everything India has to offer and bring it to the world.

• State the behavior that is guaranteed by the garbage collection system and write code that explicitly makes objects eligible for collection.

• Identify correctly constructed source files, package declarations, import statements, class declarations (of all forms including inner classes), interface declarations and implementations (for java.lang.Runnable or other interface described in the test), method declarations (including the main method that is used to start execution of a class), variable declarations and identifiers.
• State the correspondence between index values in the argument array passed to a main method and command line arguments. Identify all Java programming language keywords and correctly constructed identifiers.
• State the effect of using a variable or array element of any kind when no explicit assignment has been made to it.
• State the range of all primitive data types and declare literal values for String and all primitive types using all permitted formats, bases, and representations.
• Write code to implement listener classes and methods, and in listener methods, extract information from the event to determine the affected component, mouse position, nature, and time of the event.
• State the event classname for any specified event listener interface in the java.awt.event package.

• Determine the result of applying any operator, including assignment operators and instance of, to operands of any type, class, scope, or accessibility, or any combination of these.
• Determine the result of applying the boolean equals(Object) method to objects of any combination of the classes java.lang.String, java.lang.Boolean, and java.lang.Object.
• In an expression involving the operators &, |, &&, ||, and variables of known values state which operands are evaluated and the value of the expression.
• Determine the effect upon objects and primitive values of passing variables into methods and performing assignments or other modifying operations in that method.

• State the benefits of encapsulation in object oriented design and write code that implements tightly encapsulated classes and the relationships "is a" and "has a".
• Write code to invoke overridden or overloaded methods and parental or overloaded constructors; and describe the effect of invoking these methods.
• Write code to construct instances of any concrete class including normal top level classes, inner classes, static inner classes, and anonymous inner classes

• Recognise conditions that might prevent a thread from executing.
• Write code using synchronised, wait, notify, and notifyAll to protect against concurrent access problems and to communicate between threads. Define the interaction between threads and between threads and object locks when executing synchronised wait notify or notifyAll.

• Write code using component, container, and layout manager classes of the java.awt package to present a GUI with specified appearance and resize behavior, and distinguish the responsibilities of layout managers from those of containers.

• Describe the significance of the immutability of String objects.

• Make appropriate selection of collection classes/interfaces to suit specified behaviour requirements.

• Write code that uses objects of the file class to navigate a file system.
• Write code that uses objects of the classes InputStreamReader and OutputStreamWriter to translate between Unicode and either platform default or ISO 8859-1 character encodings.
• Destinguish between conditions under which platform default encoding conversion should be used and conditions under which a specific conversion should be used.
• Select valid constructor arguments for FilterInputStream and FilterOutputStream subclasses from a list of classes in the java.io.package.
• Write appropriate code to read, write and update files using FileInputStream, FileOutputStream, and RandomAccessFile objects.
