| -Java Codes |
| 2 | +Key Concepts in Core Java: |
| 3 | +Object-Oriented Programming (OOP): |
| 4 | + |
| 5 | +Classes and Objects: Core building blocks of Java programs. |
| 6 | +Inheritance: Mechanism to reuse code and create relationships between classes. |
| 7 | +Polymorphism: Ability to process objects differently based on their data type or class. |
| 8 | +Abstraction: Hiding implementation details and showing only essential features. |
| 9 | +Encapsulation: Keeping fields within a class private and providing access through public methods. |
| 10 | +Basic Syntax and Constructs: |
| 11 | + |
| 12 | +Data Types: Primitive types (int, char, boolean) and reference types (objects). |
| 13 | +Control Statements: If-else, switch, loops (for, while), etc. |
| 14 | +Exception Handling: Try-catch blocks, throw, throws, and custom exceptions for error handling. |
| 15 | +Collections Framework: |
| 16 | + |
| 17 | +Lists, Sets, Maps: Data structures like ArrayList, HashSet, and HashMap to store and manipulate groups of objects efficiently. |
| 18 | +Iterators: To traverse collections. |
| 19 | +Multithreading: |
| 20 | + |
| 21 | +Thread Class and Runnable Interface: Creating and managing multiple threads to execute tasks concurrently. |
| 22 | +Synchronization: Ensuring thread safety when multiple threads interact with shared resources. |
| 23 | +Java Input/Output (I/O): |
| 24 | + |
| 25 | +Streams: For reading from and writing to files, consoles, and other I/O sources. |
| 26 | +Serialization: Converting an object’s state into a byte stream to store or transmit. |
| 27 | +Memory Management: |
| 28 | + |
| 29 | +Garbage Collection: Automatic memory management that reclaims memory from objects no longer in use. |
| 30 | +Heap and Stack: Memory areas used for dynamic memory allocation and method execution. |
| 31 | +JVM (Java Virtual Machine): |
| 32 | + |
| 33 | +Platform Independence: Bytecode compiled by the Java compiler runs on any machine that has a JVM. |
| 34 | +ClassLoader: Loads classes dynamically at runtime. |
| 35 | +JIT Compiler: Optimizes bytecode into machine code for faster execution. |
