Use Spring Boot framework for creating Rest APIs
Implement CRUD operations for managing cart items
Secure APIs using authentication and authorization mechanisms
Handle error responses and exceptions gracefully
Test APIs using tools like Postman or JUnit
Java 1.8 introduced improvements in memory management with features like Metaspace and G1 garbage collector.
Metaspace replaces the permanent generation (PermGen) for class metadata storage.
G1 garbage collector is designed for better performance and predictability by dividing the heap into regions.
These improvements help in reducing memory leaks and optimizing garbage collection.
Example: Use of Metaspace allows for...
Reverse words in a string using Java program.
Split the string into an array of words using split() method
Iterate through the array in reverse order and append each word to a new string
Return the reversed string
Find duplicates in an array of strings and sort them.
Iterate through the array and use a HashMap to keep track of duplicate strings.
After finding duplicates, sort the array using a sorting algorithm like quicksort or mergesort.
Return the sorted array with duplicates removed.

Use pyspark to read the source and target tables
Identify the changes in the source data compared to the target data
Update the existing records in the target table with the new values
Insert new records for the new data in the source table

Keep the number of elements in the two heaps balanced or differ by at most 1.
If the total number of elements is odd, the median is the root of the max heap. If even, it is the average of the roots of the two he...
