Collections and java 8 features and use case in detail

Question

Accepted Answer

Java 8 features like streams and lambdas make collections more efficient and concise.

Java 8 introduced streams which allow for functional-style operations on collections.
Lambdas can be used to define custom operations on collections.
The 'filter' method can be used to select elements from a collection based on a condition.
The 'map' method can be used to transform elements in a collection.
The 'reduce' method can be used to combine elements in a collection into a single value.
The 'forEach' method can be used to perform an operation on each element in a collection.
Example use cases include filtering a list of employees by salary, mapping a list of strings to uppercase, and reducing a list of numbers to their sum.
