Terminal operations in streams produce a result or a side effect, while intermediate operations transform or filter the data.
Terminal operations are the final operations in a stream pipeline, such as forEach, collect, or reduce.

Terminal operations trigger the processing of the stream and produce a result or a side effect...
try vs try-with-resources
The 'try' statement is used to define a block of code to be tested for exceptions.
The 'try-with-resources' statement is used to automatically close resources that implement the AutoCloseable interface.
Try-with-resources is more concise and less error-prone compared to try-catch-finally.
Try-with-resources can handle multiple resources in a single statement.
Iterator is a universal interface for iterating over a collection, while ListIterator is a specialized interface for iterating over lists.
Iterator can only move forward, while ListIterator can move in both directions.
ListIterator has additional methods like previous(), hasPrevious(), and add().
ListIterator is only available for List implementations, while Iterator can be used with any collection.
Projections in Spring Data JPA allow customizing the shape of the data returned from a query.
Projections are used to retrieve specific fields or a subset of fields from an entity.
They help in reducing the amount of data transferred over the network.
Projections can be defined using interfaces or classes.
They can be used with both JPQL and native SQL queries.
Projections can be used to fetch related entities as well.
The two types of compiler in Angular are JIT (Just-in-Time) compiler and AOT (Ahead-of-Time) compiler.
JIT compiler compiles the code at runtime in the browser.
AOT compiler compiles the code before the application is deployed to the browser.
JIT compilation is slower but allows for faster development and debugging.
AOT compilation is faster but requires additional build step before deployment.
Data binding in Angular allows automatic synchronization of data between the model and the view.
Interpolation: {{ }} - binds data from the component to the view
Property binding: [] - binds data from the component to an element property
Event binding: () - binds an event from the view to a method in the component
Two-way binding: [()] - combines property and event binding to achieve two-way data flow
Promises are used for asynchronous programming in JavaScript, while Observables are used for reactive programming.
Promises represent a single value that may be available now or in the future.
Observables represent a stream of values that can be emitted over time.
Promises are eager, meaning they start executing as soon as they are created.
Observables are lazy, meaning they only start executing when subscribed to.

Constructor is a special method used to initialize an object, while ngOnInit is a lifecycle hook in Angular.
Constructor is used to create and initialize an object of a class.
ngOnInit is a lifecycle hook in Angular that is called after the component is initialized.
Constructor is defined using the constructor keyword, while ngOnInit is a method defined in the component class.
Constructor is called only once during the cre...
Inline templates are used for small, simple templates, while external templates are used for larger, complex templates.
Inline templates are defined within the component's TypeScript file using the template property.
External templates are defined in separate HTML files and linked to the component using the templateUrl property.
Inline templates are useful for small components or when the template is simple and doesn't re...

Object oriented programming is a programming paradigm based on the concept of objects, which can contain data and code.
Objects are instances of classes, which define the structure and behavior of the objects.
Encapsulation, inheritance, and polymorphism are key principles of object oriented programming.
Example: In a banking system, a 'BankAccount' class can define attributes like account number and balance, and methods
Functional interfaces are interfaces with only one abstract method, used in Java for lambda expressions.

Examples of functional interfaces in Java include Runnable, Callable, and Comparator.
