Java Basics
2 topics
Language Fundamentals
- Identify Java platform components including JDK, JRE, JVM, and the compile-and-run development cycle.
- Describe Java primitive data types (byte, short, int, long, float, double, char, boolean) and their characteristics.
- Implement variable declaration, initialization, type casting, and scope rules for Java local and instance variables.
- Analyze Java code snippets to predict output based on variable scope, type promotion, and operator precedence rules.
- Identify the key components and features of Language Fundamentals and describe their primary functions within Oracle Java Foundations.
- Deploy Language Fundamentals with integration to monitoring, logging, and alerting services for operational visibility.
- Analyze Language Fundamentals configurations to identify security vulnerabilities, bottlenecks, and optimization opportunities.
Operators and Strings
- Identify Java operators including arithmetic, relational, logical, assignment, and ternary operators with precedence.
- Implement String manipulation using String methods (length, charAt, substring, indexOf, equals, compareTo, trim).
- Explain the difference between String, StringBuilder, and StringBuffer and when to use each for text processing.
- Analyze expressions with mixed operators and type conversions to determine the correct evaluation result.
- Configure Operators and Strings with appropriate settings and parameters for a production deployment scenario in Oracle Java Foundations.
- Assess Operators and Strings implementations against best practices to identify gaps and recommend improvements.
- Name the prerequisites, dependencies, and supporting services required for implementing Operators and Strings.
2
Control Flow
2 topics
Decision and Loop Statements
- Identify Java control flow statements: if-else, switch, for, while, do-while, and enhanced for loop syntax.
- Implement nested loops with break and continue statements for controlling iteration flow in data processing scenarios.
- Configure switch statements and switch expressions with case labels, default, and arrow syntax for multi-way branching.
- Analyze control flow code to identify infinite loops, unreachable statements, and logic errors in branching conditions.
- Evaluate Decision and Loop Statements alternatives and tradeoffs to recommend the optimal approach for given constraints.
- Recognize common terminology, acronyms, and best practices associated with Decision and Loop Statements.
Methods
- Describe Java method components: return type, name, parameters, method signature, and overloading rules.
- Implement method creation with parameter passing (pass-by-value), return values, and varargs for flexible argument lists.
- Explain static versus instance methods and their access to static and instance members of a class.
- Analyze method invocations to predict which overloaded method version is called based on argument types and widening.
- List the configuration options and parameters available for Methods and describe when each is appropriate.
- Apply Methods configuration patterns to meet specific business requirements including compliance needs.
3
Object-Oriented Programming
2 topics
Classes and Objects
- Describe Java class structure with fields, constructors, methods, and access modifiers (public, private, protected, default).
- Implement classes with constructors (default, parameterized), this keyword, and constructor chaining for object initialization.
- Configure encapsulation with private fields, getter/setter methods, and immutable class design patterns.
- Analyze class designs to identify encapsulation violations, constructor issues, and access modifier misuse.
- Implement Classes and Objects following best practices for security, performance, and reliability.
- Diagnose Classes and Objects issues by analyzing metrics, logs, and configuration to determine root causes.
Inheritance and Polymorphism
- Describe inheritance concepts: extends keyword, super keyword, method overriding, and the IS-A relationship.
- Implement polymorphism with method overriding, abstract classes, and interfaces for flexible and extensible designs.
- Explain Java interface features including default methods, static methods, and functional interfaces.
- Analyze inheritance hierarchies to predict method resolution, identify casting issues, and evaluate design quality.
- Analyze Inheritance and Polymorphism configurations to identify security vulnerabilities, bottlenecks, and optimization opportunities.
- Identify the key components and features of Inheritance and Polymorphism and describe their primary functions within Oracle Java Foundations.
4
Arrays and Collections Basics
2 topics
Arrays
- Describe Java array declaration, initialization, and access with single-dimensional and multi-dimensional arrays.
- Implement array operations including iteration, sorting with Arrays.sort, copying, and searching for data processing.
- Configure ArrayList basics with add, remove, get, size operations for dynamic collection management.
- Analyze array and ArrayList code to predict output, identify ArrayIndexOutOfBoundsException risks, and evaluate approaches.
- Name the prerequisites, dependencies, and supporting services required for implementing Arrays.
- Configure Arrays with appropriate settings and parameters for a production deployment scenario in Oracle Java Foundations.
Exception Basics
- Identify Java exception types: checked (Exception), unchecked (RuntimeException), and Error hierarchy.
- Implement try-catch-finally blocks with multiple catch clauses for handling different exception types.
- Explain exception propagation with throws declaration and the distinction between checked and unchecked exceptions.
- Analyze code with exceptions to predict execution flow, identify unhandled exceptions, and recommend handling strategies.
- Explain how to troubleshoot common issues with Exception Basics including error messages and diagnostic procedures.
- Evaluate Exception Basics alternatives and tradeoffs to recommend the optimal approach for given constraints.
5
Packages and Modules
2 topics
Packages
- Describe Java package structure with import statements, fully qualified names, and the java.lang auto-import rule.
- Implement package organization with proper directory structure, access control across packages, and import conventions.
- Explain the Java module system basics with module-info.java, requires, and exports directives for modular applications.
- Analyze package and import structures to identify naming conflicts, access issues, and module dependency problems.
