Inheritance is a mechanism in Java where a new class inherits properties and behaviors from an existing class.
Allows a class to inherit fields and methods from another class
Promotes code reusability and reduces redundancy
Creates a parent-child relationship between classes
Derived class can access non-private members of the base class
Example: class B extends class A
An array in Java is a data structure that stores a fixed-size collection of elements of the same data type.
Arrays are declared using square brackets [] after the data type.
Elements in an array are accessed by their index, starting from 0.
Example: String[] names = new String[5];
Contagious storage of same data refers to multiple references pointing to the same data in memory.
Contagious storage can lead to unexpected behavior if one reference modifies the data.
Java uses pass-by-value, so when passing objects, a new reference is created pointing to the same data.
Example: If two variables point to the same object and one variable modifies the object, the change is reflected in both variables.

Using component instead of service may cause confusion and errors in the code.
Components and services are two different concepts in Java development.
Components are used for UI elements while services are used for business logic.
Using component instead of service may lead to errors in the code and confusion for other developers.
For example, if a component is used instead of a service for business logic, it may not have ...
The @Autowired annotation is used to automatically wire beans by matching the data type of the bean with the data type of the property.

Circuit breaker is a design pattern used to prevent cascading failures in distributed systems. Hystrix is a popular implementation.
Circuit breaker monitors the availability of a service and trips if the service fails repeatedly.
It helps to prevent cascading failures by failing fast and providing fallback options.
Hystrix is a popular implementation of circuit breaker pattern in Java.
It provides features like request cac
Ternary operators are conditional operators that evaluate a boolean expression and return one of two values based on the result.
Ternary operators are written in the form of 'condition ? value1 : value2'
If the condition is true, the operator returns value1, otherwise it returns value2
Ternary operators can be used as a shorthand for if-else statements
Example: int x = (a > b) ? a : b; // assigns the larger value of a and
