1. Introduction to Java

• Create and use objects to write programs in the Java Programming Language,
• Write comments into the programs,
• Declare and use variables of primitive and reference data types,
• Create and use strings and arrays,
• Use operators to form expressions,
• Write loop, conditional and branching statements.

2. Object Orientation

• Declare classes and create instances of these classes,
• Write and use interfaces,
• Overload and Override methods,
• Reuse the code in a class through inheritance,
• Use polymorphism to deal with objects in different forms,
• Organize objects in packages.

3. Containers

• Use Collections to group Java objects,
• Use List, Set, and Map interfaces,
• Choose different implementations according to your needs,
• Use iterators to access individual objects in a collection.

4. Error Handling

• Handle errors with exceptions,
• Catch and throw exceptions,
• Create and use your own exceptions.

5. Input/Output

• Get data from information sources (file on disk, standard input, etc.) using streams,
• Send data to information sinks (file on disk, standard output) using streams,
• Use readers and writers for character based I/O,
• Filter input and output streams for enhanced functionality,
• Read/Write Objects from/to streams.
