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 ValuesCovered in: Building Blocks, Operators, Core APIsUse 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 FlowCovered in: Making DecisionsCreate 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 ApproachCovered in: Building Blocks, Making Decisions, Methods, Class DesignDeclare 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.
