| Working with Java data types | - Use primitives and wrapper classes, including, operators, parentheses, type promotion and casting - Handle text using String and StringBuilder classes - Use local variable type inference, including as lambda parameters |
| Controlling Program Flow | - Create and use loops, if/else, and switch statements |
| Java Object-Oriented Approach | - Declare and instantiate Java objects including nested class objects, and explain objects' lifecycles (including creation, dereferencing by reassignment, and garbage collection) - Define and use fields and methods, including instance, static and overloaded methods - Initialize objects and their members using instance and static initialiser statements and constructors - Understand variable scopes, apply encapsulation and make objects immutable - Create and use subclasses and superclasses, including abstract classes - Utilize polymorphism and casting to call methods, differentiate object type versus reference type - Create and use interfaces, identify functional interfaces, and utilize private, static, and default methods - Create and use enumerations |
| Exception Handling | - Handle exceptions using try/catch/finally clauses, try-with-resource, and multi-catch statements - Create and use custom exceptions |
| Working with Arrays and Collections | - Use generics, including wildcards - Use a Java array and List, Set, Map and Deque collections, including convenience methods - Sort collections and arrays using Comparator and Comparable interfaces |
