In Java, == compares memory addresses while .equals() compares values of objects.
Use == to compare primitive data types and object references.
Use .equals() to compare the actual values of objects.
Improper usage can lead to unexpected results, such as comparing memory addresses instead of values.
The Java garbage collector automatically manages memory by reclaiming unused objects.
Java garbage collector runs in the background, periodically identifying and removing objects that are no longer needed.
Different types of garbage collection algorithms in Java include Serial, Parallel, CMS, G1, and ZGC.
Serial garbage collector uses a single thread for garbage collection, while Parallel garbage collector uses multiple t...

Example: List<String> names = Arrays.as...
Immutability in Java means that once an object is created, its state cannot be changed.

Advantages of immutable objects include thread safety, caching, and easier debugging.
Immutable objects are inherently thread-safe because their state cannot be modified, reducing the risk of concurrency issue...
final, finally, and finalize have different meanings in Java.
final is a keyword used to restrict the user from changing the value of a variable, making it a constant.
finally is a block of code that is always executed, whether an exception is thrown or not.
finalize is a method used for cleanup operations before an object is garbage collected.
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
Create a private static instance of the class.
Make the constructor private to prevent instantiation from outside the class.
Provide a public static method to access the instance, creating it if necessary.
Use synchronized keyword or double-checked locking to ensure thread safety.
Java annotations are metadata that provide data about a program but do not affect the program itself. They are used in frameworks like Spring to simplify configuration and reduce boilerplate code.
Java annotations are used to provide metadata about a program, such as method signatures, class definitions, etc.
In frameworks like Spring, annotations are used to simplify configuration and reduce the need for XML configurati...
Java Streams can handle parallel processing using parallel streams. Pitfalls include increased complexity and potential for race conditions.
Java Streams can be processed in parallel by calling the parallel() method on a stream.
Potential pitfalls of using parallel streams include increased complexity, potential for race conditions, and performance overhead due to thread management.
To mitigate these pitfalls, ensure that...
ArrayList is preferred for frequent retrieval operations due to fast random access, while LinkedList is suitable for frequent insertions/deletions.
Use ArrayList when frequent retrieval operations are required, such as searching for elements in a large collection.
Choose LinkedList when frequent insertions/deletions are needed, like maintaining a queue or stack.
Consider memory overhead and performance trade-offs when dec...
ReentrantLock should be used instead of synchronized when more flexibility and control over locking mechanisms is needed.

ReentrantLock supports fair locking mechanisms, ensuring that threads are granted access in the order they requested it.
Explicit unlocking in ReentrantLock reduce...
In Java, == checks for reference equality while equals() checks for value equality. Misuse of == can lead to logical errors.
Override equals() when you want to compare the values of objects instead of their references
Override hashCode() method alongside equals() to ensure proper functioning in collections like HashMap
Implement Comparable interface if you want to define a natural ordering for objects
Garbage collection in Java automatically reclaims memory occupied by unused objects using different algorithms and memory regions.
Force garbage collection in Java using System.gc() or Runtime.gc() methods.
Not recommended to force garbage collection as it can cause performance issues by disrupting the JVM's natural memory management.
Forcing garbage collection can lead to unnecessary CPU usage and potential application s...
Lambda expressions in Java 8 improve readability and maintainability by enabling concise and functional-style programming.
Lambda expressions allow writing more compact code by reducing boilerplate code.
They enable passing behavior as arguments to methods, making code more modular and flexible.
