Generics

8 Topics
1

Generics Basics

Analyze Java Generics basics, compile-time type safety advantages, parameterized types, and raw types compatibility issues.

Focuses on type safety validation, runtime ClassCastException prevention, raw types vs parameterized types, and backward compatibility.
2

Generic Classes

Analyze generic class declarations, parameterized instantiations, and static context type constraints.

Focuses on class declarations, parameter scopes, instantiating generic variables, and static variable constraints.
3

Generic Methods

Analyze generic method declarations, static generic signatures, and compiler type inference.

Focuses on type parameter placements, static generic methods, and compile-time type inference.
4

Bounded Type Parameters

Analyze bounded type parameters, single upper bounds, and multiple intersection bounds.

Focuses on upper bounds, multiple bounds syntax rules (class first, then interfaces), and compiler validation.
5

Wildcards

Analyze wildcard parameters, upper/lower bounds, and the PECS design principle.

Focuses on PECS (Producer Extends, Consumer Super) usage, wildcards capture errors, and unbounded wildcard limits.
6

Type Erasure

Analyze Type Erasure compiler processes, bridge method generations, and runtime parameter limitations.

Focuses on runtime type parameters removal, synthetic bridge methods, and compile-time casts.
7

Generic Interfaces

Analyze generic interface declarations, implementation patterns, and standard utility API contracts.

Focuses on generic interfaces (Comparable, Comparator), subclass implementation choices, and raw implementations.
8

Generics Best Practices

Analyze generics design patterns, eliminating warnings, heap pollution prevention, and SafeVarargs usage.

Focuses on unchecked warning elimination, SafeVarargs requirements, heap pollution risks, and clean API designs.
