Occur at runtime (e.g., NullPointerException , ArithmeticException ). They typically indicate programming logic errors. The Keywords: try, catch, finally, throw, throws try: Encloses risky code that might throw an exception.
Methods in the same class sharing the same name but differing in signature (argument count or types).
do-while : Post-test loop (guaranteed to execute at least once). for : Standard counter-driven loop.
Multi-threading enables concurrent execution of two or more pieces of a program to maximize CPU utilization. Creating Threads
| Feature | Overloading | Overriding | | :--- | :--- | :--- | | | Within same class or inheritance. | Between parent and child. | | Method Resolution | Compile time (based on reference). | Runtime (based on object). | | Return Type | Can be different. | Must be same or covariant. | | Access Modifier | No restriction. | Cannot reduce visibility. |
: Invoked by the GC engine just before destroying an object to perform resource cleanup. Summary Cheat Sheet for Interview Prep
Eliminates redundant code structural patterns.
In conclusion, "Core Java Complete Notes by Durga Sir" is an excellent resource for anyone looking to learn core Java. With its comprehensive coverage, easy-to-understand explanations, and well-structured format, these notes are an invaluable asset for beginners and experienced programmers alike. Whether you're looking to build a strong foundation in Java or prepare for interviews, these notes are a must-have.
Backed by a resizable array. Best for frequent retrieval operations due to random access ( time complexity).
