100% OFF- Oracle Certification : OCP SE 21 Developper 1z0-830 part1

THE OCP EXAM TOPICS COVERED IN THIS PRACTICE TEST INCLUDE THE FOLLOWING:

Handling Date, Time, Text, Numeric and Boolean Values

Covered in: Building Blocks, Operators, Core APIs

• Use primitives and wrapper classes to evaluate arithmetic and boolean expressions.
• Apply the Math API, operator precedence, type promotion, and casting rules.
• Manipulate text using String, StringBuilder, and text blocks.
• Handle date, time, duration, period, instant, and time-zone objects using the Date-Time API, including daylight saving time.

Controlling Program Flow

Covered in: Making Decisions

• Create program control flow constructs using if/else, switch statements and expressions.
• Implement loops (for, while, do-while) and use break and continue statements to control flow.

Utilizing Java Object-Oriented Approach

Covered in: Building Blocks, Making Decisions, Methods, Class Design

• Declare and instantiate Java objects, including nested class objects, and explain object lifecycle: creation, reference reassignment, and garbage collection.
• Understand variable scopes, apply encapsulation, and create immutable objects.
• Use local variable type inference.
• Create classes and records; define and use instance and static fields, methods, constructors, and initializers.
• Implement inheritance, including abstract and sealed types, and override methods (including Object class methods).
• Use polymorphism and distinguish between object type and reference type.
• Perform reference type casting.
• Apply pattern matching with the instanceof operator and enhanced switch expressions.
• Implement method overloading, including var-args.

Working with Arrays and Collections

Covered in: Core APIs

• Create and use Java arrays.
• Work with List, Set, Map, and Deque collections.
• Add, remove, update, retrieve, and sort elements in collections.
